CHAPTER 4

SAFETY The above Safety Alert Symbol means ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! It stresses an attitude of ‘‘Heads Up for Safety’’ and can be found throughout this Operator’s Manual and on the machine itself.

MANDATORY SAFETY SHUTDOWN PROCEDURE BEFORE unclogging, cleaning, adjusting, lubricating or servicing the unit:

BEFORE YOU ATTEMPT TO OPERATE THIS EQUIPMENT, READ AND STUDY THE FOLLOWING SAFETY INFORMATION. IN ADDITION, MAKE SURE THAT EVERY INDIVIDUAL WHO OPERATES OR WORKS WITH THIS EQUIPMENT, WHETHER FAMILY MEMBER OR EMPLOYEE, IS FAMILIAR WITH THESE SAFETY PRECAUTIONS. Our Company ALWAYS takes the operator and his/her safety into consideration when designing its machinery and guards exposed moving parts for his/her protection.

However, some areas can NOT be guarded or shielded in order to assure proper operation. In addition, this Operator’s Manual and Decals on the machine, warn of further danger and should be read and observed closely.

Disengage the tractor PTO.

2.

Shut off the tractor engine, place transmission in park and/or lock brake pedals to prevent any tractor movement.

3.

Remove the starter switch key and take it with you when leaving the tractor seat.

4.

Wait for all movement to stop and remove the Telescoping PTO Drive and ALL power connections from the tractor.

5.

Turn the Control Box Keyswitch Lock to ”OFF”, remove the Key and take it with you.

ONLY when you have taken these precautions can you be sure it is safe to proceed. Failure to follow the above procedure, could lead to death or serious bodily injury.

DANGER

ADDITIONAL SAFETY REMINDERS

‘‘DANGER’’ indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.

Forage Harvesters are designed and intended to ONLY be used with a mounted GEHL Company Attachment.

The GEHL Company will NOT be responsible for operator safety if Harvester is used without a properly mounted GEHL Attachment.

WARNING

Some photographs, used in this manual, may show Doors, Guards and Shields open or removed for illustration purposes ONLY. BE SURE that all Doors, Guards and Shields are in their proper operating positions BEFORE starting the tractor engine to operate the unit.

‘‘WARNING’’ indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

To ensure continued safe operation, replace damaged or worn-out parts with genuine Gehl service parts, BEFORE attempting to operate this equipment.

CAUTION

BE SURE to review and comply with ALL Safety recommendations set forth in the tractor operator’s manuals.

‘‘CAUTION’’ indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. May also alert against unsafe practices.

SAFETY (Continued) ALWAYS wear safety glasses with side shields while operating the Knife Sharpener. In addition, ALWAYS wear safety glasses with side shields whenever striking metal against metal. It is further recommended that a softer (non-chipable) material be used to cushion the blow. Failure to heed could lead to serious injury to the eye(s) or other parts of the body.

injury, follow the specific directive given in the Service chapter of this manual.

REMEMBER, it is the owner’s responsibility for communicating information on the safe use and proper maintenance of this machine.

A Harvester that has a factory–installed Metal Stop system will automatically sense the presence of ferrous metal in the Feed Roll area. A metal detection activates a Declutch Mechanism which stops the Feed Roll Drive, preventing metal from entering the Cutting Cylinder.

When metal is detected, the Feed Rolls and Attachment will stop and the Horn will sound inside the Control Box. To turn off the Horn, safely locate and remove the metal and reset the detection system, perform the following steps in the sequence given:

Good safety practice dictates that you NEVER tow an implement (without brakes) unless the towing vehicle weighs at least one-and-one half (1-1/2) times the weight of the towed implement and its load. For any public highway travel and to be in compliance with this rule, BE SURE that your tractor is heavy enough to counterbalance the weight of the Harvester and loaded wagon. Do NOT tow a loaded wagon behind the Harvester on a highway unless the wagon has operational brakes.

Signaling Device Shut–off, Metal Location & Removal, and System Resetting Procedure

NEVER use your hands to search for hydraulic fluid leaks, use a piece of paper or cardboard. Escaping fluid under pressure can be invisible and can penetrate the skin and cause a serious injury. If any fluid is injected into your skin, see a doctor at once. Injected fluid MUST be surgically removed by a doctor familiar with this type of injury or gangrene may result.

ALWAYS follow state and local regulations regarding use of a safety chain and auxiliary lighting when towing farm equipment on public highways. Restrict highway towing speeds to 20 mph (32 kmh) maximum. BE SURE to check with local law enforcement agencies for your own particular regulations. Unless otherwise prohibited, use a Slow–moving Vehicle Emblem.

Only a safety chain (NOT an elastic or nylon/plastic tow strap) should be used to retain the connection between the towing and towed machines, in the event of separation of the primary attaching system.

Move the Feed Roll Switch to “Neutral”

2.

Back the Harvester up (15 to 20 feet) so that there is NO crop under the Attachment.

3.

Reverse the crop out of the Feed Roll area and return the Feed Roll Switch to “Neutral”.

4.

Disengage the tractor PTO, shut the tractor engine ”Off”and remove the Starter Key.

5.

Turn the Control Box Keyswitch to ”Off”, remove the Key and take it with you.

6.

Wait for ALL parts to stop moving.

7.

Leave the tractor seat to remove the metal from the crop.

To safely locate the metal and remove it from the crop, once it has been detected, it is recommended that the Harvester be backed away from the windrow or crop row a sufficient distance so that the portion of the crop, containing the metal can be located and picked–out or that the small amount of crop can be set on the side for disposal later.

Our Company does NOT sell replacement tires. In addition, tire mounting, service or inflation can be dangerous. Whenever possible, trained personnel should be called to service and/or mount tires, following the tire manufacturer’s instruction. If you do NOT have such instructions, contact your tire dealer or our Company. In any event, to avoid possible fatal or serious

HYDRAULIC KNIFE SHARPENER (Fig. 8 & see Fig. 2)

Overrunning Clutch isolates the tractor PTO from the Harvester Drive Line and therefore eliminates torque loading and strain on the tractor PTO brake.

The Harvester is equipped with a factory-installed Hydraulic Knife Sharpener for sharpening the Cylinder Knives and the Cutterbar. The Sharpener is powered by the same tractor hydraulic circuit used to operate the Attachment Lift Cylinder. A Selector Valve is provided to conveniently switch between the Lift Cylinder and Knife Sharpener.

SHIFTER TRANSMISSION CONTROL The Shifter Transmission (and Electric Clutch) is used to stop the Feed Rolls and the Attachment, to run them forward (to bring the crop into the Cutting Cylinder), or to run the Feed Rolls backwards (to reverse plugging material out of the Feed Roll area). Shifting the Transmission is accomplished by activating Switches on the tractor-mounted Control Box. Refer to the Operation chapter in this manual for specific details.

CAUTION BEFORE leaving the tractor, ALWAYS turn the Control Box Keyswitch to OFF and remove the Key and take it with you for your own safety and to avoid unnecessary drain on your tractor battery.

SAFETY CHAIN & TRANSPORT LIGHTING (Fig.10)

CAUTION

As required or when desired, the Harvester should be equipped with a safety chain for operation on public highways. Refer to the Optional Features & Accessories chapter for ordering information. The safety chain should be attached to the tractor and Harvester as shown.

ALWAYS follow state and local regulation regarding use of a safety chain and transport lighting when towing farm equipment on public highways. ONLY a safety chain (NOT an elastic or nylon/plastic tow strap) should be used to retain the connection between the towing and towed machines, in the event of separation of the primary attaching system.

BE SURE to check with local law enforcement agencies for your own particular regulations.

Unless otherwise prohibited, use a Slow-moving Vehicle Emblem.

CHAPTER 6 OPERATION NOTE: This chapter is divided into two separate sections. The first section pertains to all Harvester models. The second section only pertains to a Harvester with Metal Detector system.

ALL HARVESTER MODELS GENERAL INFORMATION

WARNING WARNING

When any part of the Harvester other than the Feed Rolls or Attachment becomes plugged, stop Harvester operation IMMEDIATELY by moving the Feed Roll & Attachment Selector Switch to NEUTRAL. Then, disengage the tractor PTO and wait for ALL movement to STOP. Then, exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (as described on page 8). BEFORE leaving the tractor seat to remedy the plugging problem, turn the Control Box Power Keyswitch to OFF, remove the Key and take it with you.

BEFORE starting the tractor engine and running the Harvester, review and comply with ALL applicable recommendations set forth in the SAFETY chapter.

Emergency Shutdown In an emergency or in case a foreign object enters or becomes lodged in the Feed Roll area, STOP Harvester operation IMMEDIATELY by disengaging the tractor PTO.

Entering the Crop

Start–up

NOTE: The PTO should be brought–up to the rated 1000 RPM before entering the crop and then maintained at that speed while harvesting.

WARNING

To maintain the rated RPM, choose the correct tractor gear position to adjust ground speed rather than the tractor throttle. If the tractor engine does bog–down, the Speed Monitor, which detects a slow–down of material in the Spinner Tunnel, will stop the Feed Rolls and allow the engine to regain its speed.

BE SURE ALL Guards and Shields are properly secured in place BEFORE starting the tractor engine and operating the Harvester.

ALWAYS engage the tractor PTO at idle speed when starting–up the Harvester. The first time the Harvester is being operated, shift the Feed Roll Transmission through its three positions to make sure that all mechanisms are operating properly. In addition, operate the Lift System and the Deflector and Cap control systems to verify proper operation.

Sharp Cutting Cylinder Knives and proper Cutterbar adjustment will provide for more efficient Harvester operation and will reduce horsepower waste.

Leaving the Crop Maintain the rated RPM for a short time after leaving the crop. This will allow the Harvester Blower, Cutting Cylinder and Deflector to be emptied. After the forage stops coming out of the Deflector, the PTO can be disengaged or the tractor throttled down.

NOTE:

To protect the Drive Line components of both the Harvester and the tractor, avoid engaging the tractor PTO at faster than idle speed.

Fig. 11: Control Box* with Metal Stop Decal * Control Box for non-Metal Stop Harvester does NOT have extra Decal in lower right-hand corner of Box.

NOTE: Except for the brief time that the ”HOLD FOR REVERSE” Handle is activated, gearing in the Transmission is always in the Forward condition. It has NO neutral. The Neutral condition is created solely by opening the Electric Clutch.

OPERATING FEED ROLLS & ATTACHMENT (Fig. 11) Move the ”AUTO–OFF–MANUAL” Mode Switch to ”AUTO” and leave it there. With the Power Keyswitch ON, the Feed Rolls and Attachment are controlled by the FEED ROLLS & ATTACHMENT ”SELECTOR” Switch. Toggling the Switch to ”FWD” (forward) will immediately cause the Electric Clutch to close and, if the PTO is engaged, the Feed Rolls and Attachment will run to feed crop into the Knives. Toggling into ”NEUTRAL” will open the Clutch and stop all Feed Roll and Attachment motion. To back material out of the Harvester, move the Toggle Switch to ”REV” (reverse) and, in addition, rotate and hold the spring–loaded ”HOLD FOR REVERSE” Handle to the right (counterclockwise); release the Handle to automatically open the Clutch and stop reversing.

Printed in U.S.A.

The ”MANUAL” and ”OFF” positions of the Mode Switch are used only when there is a problem with the Automatic circuit. In this mode, the Clutch closes and runs the Feed Rolls and Attachment Forward, when the Switch is toggled to ”MANUAL” and the Clutch opens when the Switch is toggled to ”OFF” to stop Feed Rolls and Attachment. While operating in MANUAL condition, there is NO Reverse capability NOR will the Speed Monitor, Metal Stop system or Load Sensors operate.

906623/CP1097

Chapter 6 – Operation

NOTE:

If disconnecting the Metal Stop system and the Speed Monitor does NOT allow the Auto-Maxr system to operate and it can NOT be repaired immediately, proceed as follows. Operate Harvester with the “AutoManual” Switch in “Manual” and shut-off the Feed Rolls and Attachment by moving the “Auto-Manual” Switch to “Off”. The “Manual” Switch position should only be used as a means to finish the day’s work before making repairs. DO NOT use “Manual” Switch all season long.

When operating in the ”MANUAL” mode, be extra cautious to avoid plugging the Feed Rolls or the Attachment because the reversing function is inoperative in this mode.

CONTROL BOX FOR LOAD SENSOR (AND METAL STOP) HARVESTER MODELS (Figs. 11 & 12)

UNPLUGGING (See Fig. 11)

Place the “Auto-Manual” Switch into the “Auto” position and LEAVE IT THERE. This will allow the Auto-Maxr system to protect the Harvester. No AutoMaxr Shut-Off systems will operate with the “AutoManual” Switch in “Manual”. The “Manual” Switch position allows the Feed Roll and attachment Drive Load Sensors to ratchet when they are overloaded. The Load Sensors may ratchet only a few seconds at a time, but the total accumulative ratcheting life is less than 7 minutes. The “Manual” Switch position should be used as little as possible to avoid damaging the Load Sensors.

The Load Sensors should never ratchet while the “Auto-Manual” Switch is in “Auto”.

WARNING When any part of the Harvester other than the Feed Rolls or Attachment becomes plugged, stop Harvester operation IMMEDIATELY by moving the Feed Roll & Attachment Selector Switch to NEUTRAL. Then, disengage the tractor PTO and wait for ALL movement to STOP. Then, exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (as described on page 8). BEFORE leaving the tractor seat to remedy the plugging problem, turn the Control Box Power Keyswitch to OFF, remove the Key and take it with you.

If the Metal Stop system malfunctions and can NOT be repaired immediately, disconnect the Wiring Harness Plug inside the Feed Roll Drive Frame, move the Stop Pawl Spring to the “bypass” position, and keep the “Auto-Manual” switch in “Auto”. Refer to the Metal Stop section in this chapter.

Blower If the Blower becomes plugged with chopped forage, proceed as follows to clear it:

1

1.

Exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (as described on page 8).

2.

Before cleaning–out the Blower, remove the Rear Shield and observe the Blower Shaft to determine if the Blower is still rotating; wait for the Cylinder to stop turning before proceeding.

NOTE:

Even if the Blower Outlet is plugged, the Fan could continue to rotate.

1 – Plug (Tape Ends of Plugs to Prevent Shorting-out Against Frame)

3.

If necessary, remove the Spinner Chute Cover to help gain access to the bottom portion of the Blower.

4.

After the forage has been cleaned–out of the Blower and the Fan turns freely, check the Blower Outlet to insure that it is NOT also plugged.

5.

If the Blower Outlet is plugged, use a rod to poke down from the top through the Deflector Cleanout Holes.

Fig. 12

NOTE: Using electrician’s tape, cover the ends of the Plug and Socket to keep dirt out of both parts.

If the Speed Monitor system malfunctions and cannot be repaired immediately, disconnect the Speed Monitor Plug at the side the Spinner Gearbox and keep the “Auto-Manual” Switch in “Auto”.

Chapter 6 – Operation

6.

After the Fan is free to rotate, replace the Spinner Chute and Cleanout Covers and reattach the Rear Shield.

1.

Exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (as described on page 8).

2.

After all Cutting Cylinder and Blower movement has STOPPED, remove the Cleanout Cover from the base of the Deflector.

3.

Remove any plugging material which may be wedged inside the Deflector or Deflector Extension through the Cleanout Cover(s).

4.

Check and, if necessary, unplug the Blower and Cylinder areas. Refer to the information under the Blower and/or Cylinder topics, earlier in this chapter, to unplug these areas.

Cylinder If the Cutting Cylinder becomes plugged with forage, proceed as follows: 1.

Exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (as described on page 8).

2.

Inspect the Cylinder by removing the Cover.

Check to see if the Knives are wedged with forage.

If they are hung–up, do the following: a.

Pry the Cylinder backward as far as possible so that the Cylinder can build–up momentum before it enters the crop.

b.

Reinstall and secure the Cylinder Cover and Guards.

c.

Start the tractor, run the engine at 3/4 to full throttle and engage the PTO to clear the plug; this may partially shear the Impact Pins.

d.

Again, exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (as described on page 8) and then check the Cylinder to make sure it is unplugged.

e.

Inspect the Main Drive Impact Pins (and replace them, if necessary) following the procedure as described under the ”OVERLOAD PROTECTION – Main Drive Line” topic, later in this chapter.

Feed Rolls By design, the Feed Rolls allow various mat thicknesses to pass between them. If however, the mat thickness tries to exceed 6” (152 mm) or if an obstruction gets between the Feed Rolls, the Load Sensor will detect this condition. This will cause the Electric Clutch to open and stop Feed Roll operation and the crop will NOT feed into the Cutting Cylinder.

When an overload condition does occur, reset the Clutch by setting the Feed Roll & Attachment Selector Switch to NEUTRAL (center position) and then, return it to FWD (forward) position. Do NOT idle the tractor when shifting the Feed Rolls. If the overload condition is NOT cleared by merely resetting the Electric Clutch, move the Feed Roll & Attachment Selector Switch to the REV (reverse position) and rotate the HOLD–FOR–REVERSE Switch to reverse the material back out about 6” (152 mm). Then, reset the Feed Roll & Attachment Selector Switch to the FWD (Forward position).

NOTE: Special care should be taken so as NOT to reverse the crop too far. Corn should NOT be allowed to back–out past the Front Feed Rolls or it will NOT feed back in when the forward mode is re– engaged. Hay should be watched so that the Attachment Auger does NOT ”auger” the material sideways and jam it into the Attachment Sidesheets; although it should NEVER need to be backed up that far.

WARNING After the Cylinder is freed and cleaned–out and the Impact Pins have been inspected (and replaced), reinstall all Guards and Covers BEFORE resuming Harvester operation.

3.

Insert the Control Box Key, turn the Power On, start and idle the tractor, engage the PTO, bring the tractor up to rated operating speed, shift to “Forward” and resume harvesting.

WARNING NEVER attempt to hand feed crop into the Feed Rolls as the crop will feed faster than you can react to let go.

Lower Feed Roll Drive (Fig. 14)

These figures represent an uninterrupted run and most customers should multiply them by 0.7 to account for time spent changing wagons, traveling headlands and any other non–harvesting activities.

The Lower Feed Roll Drive is protected by a Slip Clutch on the Input Shaft. The Clutch is factory adjusted and should require NO additional adjustment. If the Clutch is slipping, exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (as described on page 8) and then remove the cause of the overload before attempting to resume harvesting.

”Tractor Horsepower” is the PTO dynamometer rating.

From it was subtracted a suitable amount for pulling the tractor itself, the Forage Harvester and a half–loaded wagon across the ground at a speed appropriate for the listed capacity.

OVERLOAD PROTECTION Main Drive Line (Fig. 13) 3

The Main Drive, which is connected through an Overrunning Clutch assembly to the Input Shaft of the Bevel Gearbox, is protected from “sudden start” impact damage by a flanged connection and Impact Pins. The Flange is secured to the Overrunning Clutch with (2) Impact Pins (5/16 x 3–1/4 Grade 5 Cap Screws) with double–Nuts (2 5/16 Hexagon Nuts per Pin). These Pins are capable of transmitting approximately 675 hp and are designed to break only under a high impact caused by the engagement of the tractor PTO while the tractor is running at a high RPM. The Flange is equipped with a Grease Fitting in the Pilot Area to prevent the Shaft from seizing; the Fitting MUST be greased daily.

Additional Impact Pins are provided in the Toolbox.

Fig. 16

INTRODUCTION (Fig. 16)

When a ferrous metal object passes through the Magnetic Field over the Lower Front Feed Roll, a low voltage signal is sent to the Amplifier Box which is mounted on top of the Feed Roll Housing. When the signal reaches the Amplifier Box, an electrical contact is opened which, in turn, interrupts power to the Pawl Solenoid. The Feed Rolls are stopped immediately by the Stop Pawl. At the same time, the Electric Clutch opens to stop power to the Attachment and Feed Rolls.

The Metal Detector model Harvester contains a Metal Stop system which is designed to prevent ferrous metal (containing iron) objects from entering the Forage Harvester Cutting Cylinder. It can be used with all mounted Attachments, except those which use a steel Cover over the Lower Front Feed Roll, such as the Snapper Attachment. A “bypass” procedure is provided for use with these Attachments.

Printed in U.S.A.

Chapter 6 – Operation

When the Metal Stop system is functioning properly, the following ferrous metal objects can be detected: —

hitchpins

—

scrap iron

—

bolts

—

wrenches

—

rake teeth

—

steel pipe

—

steel fence posts

—

plow points

—

sickle sections

—

chains

—

nails

—

wire

—

rocks containing iron

action of the feeding mechanism which causes most of the ferrous metal objects to descend to the bottom of the incoming crop material.

As with all GEHL equipment, the Metal Stop system is initially warranted against defects in material and workmanship. However, because of the above described conditions, the Metal Stop system can NOT and MUST NOT be expected to be 100% effective at detecting iron objects.

GENERAL INFORMATION (See Fig. 11) The Metal Stop system is operated from the tractor seat with the Harvester Control Box. A ferrous metal detection causes the Amber Signal Light on the Harvester to “flash” and the Control Box Buzzer to sound.

NOTE: Sounding of the Control Box Buzzer also signals maximum capacity or “low speed”.

The flashing Amber Light only signals for a metal detection. The Harvester can NOT be operated until after the Metal Stop system is reset.

Regardless of system adjustment, the following objects will NOT be detected: —

aluminum

—

stainless steel

—

wood

—

tile

—

cement

—

stones

To turn off the signaling devices, safely locate and remove the metal and, restore the detection system to be able to resume harvesting, perform the steps in the sequence given on the Control Box Decal or detailed in the Safety chapter.

SYSTEM START–UP (Figs. 17 & 18 & see Fig. 11)

NOTE:

The optimum performance of your Metal Stop system depends on it being kept in proper operating condition and properly maintained. Like any other electrical system, the Metal Stop system is subject to malfunction due to defects, occasional breakdowns, misuse and human error. As with any mechanical device, components can breakdown or wear. Therefore, it is highly recommended that the system be tested on a daily basis.

To initially start–up the Metal Stop system or reset it, after metal has been detected and removed, perform the ”Start–up or Reset Procedure” given, with the tractor PTO disengaged.

If the Amber Light on the Harvester does NOT go out and remain “off”, the Stop Pawl is probably stuck in the Ratchet Wheel., as shown in the illustration provided.

When the Pawl sticks, it causes the Circuit Breaker , in the amplifier Box to open.

The Metal Stop system is only sensitive to moving objects; keep this in mind when performing the test procedures. There is also an area, at the center and the ends of the Lower Feed Roll, where sensitivity is reduced. Sensitivity also decreases as the distance from the object to the Lower Front Feed Roll increases.

During normal operation, a high detection rate is achieved because of the forces of gravity and the stirring

Printed in U.S.A.

Wait about 10 to 15 seconds for the (heat activated) Breaker to cool. Then, idle the tractor, engage the PTO and reverse the Feed Rolls until the Rolls move. The Amber Light should go out and remain. “off”. Now, the Metal Stop system is ready to use. After the preceding steps are performed, idle the tractor and engage the PTO and start (resume) harvesting.

ACTION

REASON

1.

Move FEED ROLL Switch to ”Neutral”.

This stops the Buzzer.

2.

Stop forward travel and back-up the tractor.

This separates crop in the Feed Rolls from the crop on the ground.

3.

Reverse the Feed Rolls.

This remove the crop (Containing the metal) from the Feed Rolls.

4.

Shut-off the tractor PTO and engine.

This keeps the Harvester from running unnecessarily.

5.

Shut the Power Keyswitch OFF, remove the Key To prevent undesired or unexpected system activation. and take it with you.

6.

Wait for ALL parts to STOP moving.

To avoid being injured by moving parts.

7.

Remove the metal from the crop.

This should be done with the portion of the crop, containing the metal, on the ground.

The preceding action also occurs when the Mode Selection Switch is turned “OFF” as well as when Power is interrupted to the Metal Stop system.

2.

With NO one near the Harvester, reset the Metal Detector system and start–up the Harvester. Slowly move forward and harvest the windrow.

A ferrous metal detection is indicated by the Amber Light on the Harvester flashing and the Control Box Buzzer sounding. If the Amber Light is NOT flashing, the Control Box Buzzer is indicating a Load Sensor or Speed Monitor activation..

3.

The ferrous metal object will be detected a second time.

4.

Repeat the following standard procedure to remove the metal.

When a ferrous metal detection occurs, carry-out the procedure detailed in the “Detection Reaction Procedure” given.

WARNING BEFORE searching for detected metal, exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8). REMEMBER also that, when PTO is engaged, Cylinder and Blower continue to rotate when Feed Rolls and Attachment are stopped.

b.

Reverse the Feed Rolls

c.

Shut off the tractor PTO and engine

d.

Shut the Power Keyswitch ”Off”, remove the Key and take it with you

e.

Wait for ALL parts to stop moving

f.

Remove the metal from the crop

NEVER attempt to hand feed crop into the Feed Rolls as the crop will feed faster than you can react to let go.

Making a hand–made windrow and driving slowly into it should drastically reduce the amount of material that has to be searched. The small amount of material going into the Feed Rolls should also make the second detection more likely to occur.

Take the hay that was reversed–out of the Hay Attachment and spread it onto the ground in front of the Attachment.

Printed in U.S.A.

Stop forward travel and back–up the tractor

WARNING

The ferrous metal object will usually be within 1 foot of the end of the crop which was about to enter the Cutting Cylinder. If the metal object can NOT be discovered through an initial search, continue the search after exercising the proper precautions in the following manner: 1.

a.

However, it is possible that the metal object stayed on the ground when harvesting the hand–made windrow or during the search.

31

906623/CP1097

Chapter 6 – Operation

The Metal Detector system resets itself when the Feed Rolls are reversed to remove the detected ferrous metal.

The Metal Stop system sometimes may also detect metal while the Feed Rolls are being run in reverse. This type of metal detection will cause the Amber Light, on top of the Harvester Feed Roll Drive Frame, to continue flashing. Reset the system by shifting to reverse to make the Light go off.

It may be desirable or otherwise necessary to bypass the Metal Stop system for the reasons mentioned in the previous paragraph or, if a malfunction occurs that can NOT be remedied quickly. After the Metal Detector system is bypassed, the Harvester can be operated in the same manner as a unit without the Metal Detector system. Bypassing the system allows you to operate in either the “OFF-MANual” or “AUTOmatic” mode and, if desired, use a Snapper Attachment.

BYPASSING THE METAL DETECTOR SYSTEM (Figs. 19 & 20)

1 1

1 – Plug (Tape Ends of Plugs to Prevent Shorting-out Against Frame)

2

Fig. 20: Plug in Feed Roll Drive Frame

Procedure To bypass the Metal Detector system, refer to the illustrations provided and proceed as follows:

1 – Stop Pawl in “Bypassed” Position 2 – Pawl Spring

Fig. 19: Stop Pawl Spring in “Bypassed” Position

1.

Move the Pawl Spring from the ”Operating” position to the “bypassed” position, as shown. After the Spring is moved, make sure that the Stop Pawl is away from the Ratchet Wheel.

2.

Disconnect the Plug inside the Feed Roll Drive Frame, as shown. Using electrical tape, cover the ends of the Plugs to keep dirt out of the Plug sockets. Also, fasten disconnected Plugs where they can NOT rub on Upper Feed Roll Drive Shaft.

Reasons Why The Metal Detector system can NOT be used with the Harvester Control Box Mode Selector Switch in the “OFF-MANual” position. The “OFF-MANual” position” mode cancels ALL automatic Shut-off Devices of the Harvester’s electrical system, including the Metal Stop system. Furthermore, the system can NOT be used on an Attachment using a steel Cover over the Lower Front Feed Roll, such as the Snapper Attachment.

906623/CP1097

To restore the Metal Detector system, return the Spring and Plugs to their original operating positions and return the Control Box Switch to the “AUTOmatic” mode.

Operate the tractor and the hydraulic lift controls yourself. Make the Attachment and Harvester Lift system adjustments by yourself.

For your own safety, keep everyone away from the tractor and Harvester while making the following adjustments.

4.

Axles & Wheels

Lift Height (Fig. 22)

The Harvester Axles and Wheel Spindles have several mounting hole positions for adjusting the Wheels and Axles in or out and several hole positions are provided in the Spindle assemblies for adjusting the height of the Harvester with respect to the mounted Attachment and the ground conditions. Refer to the Tires, Wheels & Spindles topic (beginning on page 45) for appropriate positions related to the different Attachments.

4 3

The Downstop Adjustment can be used to limit how far down the Lift Arms will travel when a Row Crop Attachment is being used on the Harvester. Adjust the Downstop so that, with the Lift Cylinder retracted, the height to which the Attachment will be lowered is that level which will keep the skids off the ground and the rotary sickles out of the dirt and stones. To adjust the Downstop position: Extend lift cylinder and remove Downstop Pin.

2.

Lower the Attachment to the desired position.

3.

Insert Downstop Pin into its highest hole possible.

Lift Arms will raise the Feeder Attachment. The Cam requires readjustment anytime the mounted Attachment raises too high and strikes the Harvester Feed Roll Housing.

3

To adjust the Cam, retract the Lift Cylinder and loosen the 3/4I Bolt which clamps the Cam between the Lift Assembly Plates. Loosen the Bolt only enough to allow the Cam to be rotated. Turn the Cam to position its high side toward the Lift Link for the maximum upward travel of the Attachment or, turn the Cam to position its low side toward the Lift Link for the minimum upward travel of the Attachment. After the desired position is tested and obtained, retighten the Nut on the 3/4I Bolt to lock the Cam in the position selected.

Lift Spring (Fig. 23)

Belt Idler (Fig. 24)

Fig. 23

The Harvester Lift Spring is provided to counterbalance the weight of the Attachment to either lighten its pressure on the ground or to better enable it to raise up and over stones, ruts or obstacles in the field. Spring tension can be readjusted to match the flotation requirements of various Attachments, as required.

1

2 3

5

To adjust Lift Spring tension, first completely retract the Lift Cylinder and lower the Attachment to the ground to determine the required Spring length setting. Then, using two wrenches, hold the Spring Nut with one wrench and turn the Spring Bolt with the other wrench to obtain the desired tension.

4

NOTE:

Raise the Attachment to reduce the spring load on the Spring Adjusting Bolt which will make it easier to turn the Bolt . Then, lower the Attachment again to gauge the float effect of the Spring.

1 – Drive Belt 2 – Idler 3 – Belt Guide 4 – Spring Strap 5 – Idler Arm

For a Hay Attachment, the Spring tension should be adjusted to counterbalance the Attachment. It should take approximately 50 lb (22.5 kg) of lift at the Hay Hold-down Bar to raise the Attachment.

Fig. 24

Belt tension is maintained by a Spring-loaded Belt Idler.

Tension on the Belt is factory set and requires NO further readjustment unless the Belt slips and becomes hot. In this case, the Belt tension MUST be increased by stretching the Spring further. The Spring can be stretched by positioning the Bolt, which passes through the Spring Strap and Idler Arm, in the second hole from the end of the Spring Strap. This will increase the Spring length by approximately 1I (25.5 mm).

If a Water Tank option is being used on the Hay Attachment, adjust the Lift Spring to provide maximum tension. Maximum tension can be adjusted whenever a Row Crop Attachment is mounted, provided the Row Crop Attachment still lowers all the way to the Downstop without assistance. However, many users leave the Spring set in the hay attachment position.

Chapter 7 – Adjustments

Belt Guide (Fig. 24)

3.

Check to see if the Blower Paddle Arms are bent; replace or straighten, as required.

The Belt Guide is used to prevent the Belt from coming off the Idler. Position the Guide so that there is a 3/16I (5 mm) gap between the Guide and the Belt when the Idler is resting on the Belt. To adjust the Guide position, loosen the 1/2I Idler Bolt, slide the Guide in its slots to the correct position and retighten the Bolt.

4.

Loosen the four 1/2I Hexagon Nuts on each Paddle only enough so that the Paddles can be tapped toward the Rim Sheet. Access to the Nuts can be gained through the Spinner Chute opening in the rear Sidesheet. Align the Paddles over their full 4-3/4I (121 mm) width so that the Tips are 1/32 to 1/16I (0.8 to 1.5 mm) away from the Rim Sheet.

Drive Belt (Fig. 24) The Drive Belt can be removed, for replacement, by raising the Idler above the Belt, pushing the slack Belt toward the Blower and, then lowering the Idler until the Spring is loose. Use an appropriate length of 1I (25 mm) diameter pipe, or equivalent, for additional leverage.

1

2

Fan Paddles (Fig. 25) Over long periods of Harvester use, the tips of the six Blower Fan Paddles will wear and therefore require readjustment. The position of the Fan Paddles should be checked (and, if necessary, readjusted) after every 100 hours of operation.

3

Each Paddle Tip should be approximately 1/32I to 1/16I (0.8 to 1.5 mm) away from the Blower Rim Sheet at the 6 o’clock (bottom) position. An excellent method for checking the setting is to place a nickel and a dime side by side on the Rim Sheet. When the Paddle is rotated across the coins, it should pick up the nickel and leave the dime. To adjust the Paddles, proceed as follows: 1.

1 – Spinner Tunnel Opening 2 – Paddle Arms 3 – Blower Fan Paddle

Fig. 25

NOTE: If after several adjustments of the Paddles, they cannot be moved any closer to the Rim Sheet, replace them according to the procedure outlined under the Blower Fan Paddle topic in the Service Chapter of this manual.

Make sure the Rim Sheet is clean (free of grass, gum, or dirt). Clean the Rim Sheet by running wet forage through the Harvester or by scraping it, if you do NOT have an accessory Water Tank.

5.

Check the screws and nuts which secure the Paddle Arm to the Blower Disc to see that they are properly secured.

6.

After all Paddles are adjusted and the attaching hardware is tightly secured, rotate the Fan again (by hand) to insure that it turns freely; if NOT, check and remove the obstruction.

7.

Replace the Rear Shields and Guards. Run the Harvester at idle speed and listen for noise from the Blower.

CAUTION BE SURE to exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8) BEFORE proceeding.

2.

Increase the tractor RPM to full throttle and again listen for noise from the Blower. If any noise problem is heard, exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8) and then proceed to identify and correct the problem.

Check the Rim Sheet for dents and holes; replace if necessary.

Chapter 7 – Adjustments

CUTTERBAR (Figs. 26, 27 & 28) The two routine maintenance procedures which have the most significant effect on the quality of cut and fuel efficiency are Knife sharpening and Cutterbar adjustment. Frequent sharpening of the Knife edge accompanied by the proper Cutterbar adjustment, will significantly increase the life of the Knives and the Cutterbar as well as reduce the amount of fuel required to chop the forage. In most cases, daily sharpening of the Knives and proper adjustment of the Cutterbar to the Knives will be sufficient. However, in areas where the soil is excessively sandy, more frequent Knife sharpening and Cutterbar adjustment may be necessary.

Fig. 27: Cutterbar Right Side Adjustment Component Replacement Detail

Setting the Cutterbar requires listening for the Knives to tick the Cutterbar but, it is possible for the Knives to hit the right side of the Cutterbar when you are adjusting the left side and vice-versa, thus giving a wrong indication of the closeness of a Knife to the Cutterbar.

If you follow the method given here, the Knife will always tick the Cutterbar on the side that is being adjusted.

NOTE:

Adjust the left side of the Cutterbar towards the Cutting Cylinder until a ticking is heard and then, back the left side away from the Cylinder only enough to stop the ticking sound.

Again, bring the right side of the Cutterbar to tick and then, back it off enough to stop the ticking.

Adjust the center of the Cutterbar to a slight ticking and retighten the Center Cutterbar Adjusting Lock Bolt. The Cutterbar is now setup all the way across and backlash toward the Knives has been removed.

When the cutting edge of the reversible Cutterbar NO longer stays sharp, the Cutterbar can be removed and changed (end-for-end) to place a new sharp edge toward the Knives. When one or both edges of the Cutterbar are NO longer sharp, one or the other can be renewed with the Knife Sharpener; refer to the Service chapter for details. After both edges are worn-down and can NO longer be renewed, the Cutterbar MUST be removed and replaced with a new Cutterbar.

A Screen recommendation table is also provided to aid in proper Screen selection.

After all the Knives have been sharpened and adjusted to obtain a round Cylinder, readjust the Cutterbar following details in this chapter. Refer to the Service chapter for directives on sharpening the Knives. BE SURE to remove the Knife Set-up Rod and reinstall the Spinner and Cylinder Covers and the Screen before resuming harvesting.

NOTE: To minimize the increased horsepower requirements, BE SURE to use the Sprocket which gives the longest acceptable Length-of-Cut in con junction with the Screen. It should also be understood that the use of a Recutter Screen increases horsepower requirements and reduces harvesting capacity.

LENGTH-OF-CUT (See Fig. 30) The Harvester Length-of-Cut is regulated by two factors: the number of Cylinder Knives and the Lengthof-Cut Sprocket which is mounted on the Shifter Transmission Output Shaft.

NOTE: To reduce the shelled corn loss from the Lower Feed Rolls, use a shorter Length-of-Cut Sprocket.

Refer to the Length-of-Cut chart provided for Sprocket and Knife combinations. Refer to the Service chapter for Knife removal and replacement details.

After the preceding adjustments are made, recheck the Solenoid operation to insure that the Stop Pawl moves freely.

To operate with maximum capacity sensing capability, the load sensing Contact Points for each Sensor (one on the Feed Roll Drive and one on the Attachment Drive) MUST be maintained with a 0.036 to 0.060I (0.9 to 1.5 mm) gap between the Sensor Contact Point and the adjacent plate Sprocket. A lesser gap causes the Contact Point to make contact with the Sprocket due to Sprocket wobble or under lighter loads. A greater gap causes the Load Sensing device to ratchet without releasing the Electric Clutch.

METAL STOP SOLENOID & STOP PAWL (Fig. 37) When the Solenoid is retracted (Normal Operating Position), the Stop Pawl is to be held 1/8″ (3 mm) away from the highest point on the Ratchet Wheel as shown.

To adjust this distance, first loosen the (3) Bolts in the Solenoid Mount and slide the Mount towards or away from the Ratchet Wheel. After the 1/8″ (3 mm) clearance is obtained, tightly secure the (3) Bolts.

The Scraper, for the Rear Lower Smooth Feed Roll, can be adjusted or removed (if necessary) from outside the Harvester. The Scraper should be maintained in contact with the entire width of the Feed Roll. If readjustment is required, loosen the 1/2I Hexagon Nuts on each end of the Scraper and tap the Scraper ends down. If material is caught between the Scraper Tip and the Feed Roll, remove the Scraper by loosening the Nuts to permit the mounting bolts to drop-down in the slots in the Scraper and Cutterbar Support.

The (3) Rings, between the Solenoid and the Stop Pawl, MUST NOT be twisted. The Ring in the Solenoid Eyebolt and the one in the Stop Pawl are to be horizontal (positioned sideways). The center Ring is to be vertical (perpendicular to the other two). Rotate the Eyebolt, inside the Solenoid Boot to untwist the Rings.

Chapter 7 – Adjustments

Pull the Scraper out the right side and clean it. If the Scraper is badly worn or bent, replace it. Reinstall the Scraper by reversing the above procedure. Raise the 1/2I Bolts and Nuts, at each end of the Scraper, in the slots and tighten the Nuts so they are snug. Then, tap the ends of the Scraper down and secure it by tightening the Nuts.

power is NOT wasted due to hairpinning of the crop at the edges of the holes.

NOTE: When the Scraper is reset, BE SURE to set the Stem Deflectors down against the Cutterbar and 1/32I (0.8 mm) forward of the cutting edge of the Cutterbar on its lower end. Carefully rotate the Cutting Cylinder (by hand) to make sure the Knives do NOT strike the top of the Stem Deflectors. MAKE SURE that the Stem Guide Bolts are tight. Loose Bolts will allow the crop to push the Guides into the Knives and severely damage the Cutting Cylinder.

To adjust the mounted Screen, proceed as follows:

Periodically check the area between the Scraper and Smooth Feed Roll to make sure that it is clean. This area can be cleaned from the outside of the Harvester by pushing a rod through the hole in the Sidesheet, between the Scraper and Feed Roll. It is build-up in this area that causes higher loads which wear the Sprockets and increase horsepower consumption.

SQUARE HOLE SCREENS (Fig. 38) Square Hole Screens are available in hole sizes from 3/4 to 4I (19 to 100 mm). Refer to the Setup & Assembly chapter for installation details.

1.

Remove the Spinner Cover and Cylinder Cover.

2.

Loosen the Cam Bolts just enough so that the Cam Nuts can be rotated.

3.

Turn the Spinner Disc (by hand) and, starting with the forward, then the middle and then, the rear Cams, turn each Cam Nut counterclockwise on the right side and clockwise on the left side until the Screen stops the Cutting Cylinder. Then, backoff the Nuts slightly. Repeat this process for all of the Cam Nuts.

4.

After all of the Cam Nuts are adjusted, repeat the adjustment because the last adjusted Cams will affect the position of the Screen with respect to the first adjusted Cams. Adjust the Screen as close as possible to the Knives; a slight ticking is permissible.

5.

Retighten the Cam Bolts.

6.

Replace the Cylinder and Spinner Covers and tightly secure them.

7.

Reinstall the Telescoping Drive and start the Harvester. Some ticking will probably occur; this is permissible and even desirable since operating the Harvester will eventually eliminate it.

High spots on a Screen can be beaten-down with a heavy bar, if they are NOT too close to the Screen Flanges. The Screen can only be moved about 1/4I (6 mm) inward from its initial position, with the Knives set out to a 9I (228 mm) radius. If the Screen can NOT be moved into the Knives far enough, the Knives will have to be reset and sharpened.

NOTE: Screens are also reversible so that, when the edges of the Screen holes become rounded, the Screen can be removed, rotated and replaced with the sharp edges facing the Knives.

STEM DEFLECTORS (See Fig. 28)

Fig. 38

Right and Left Stem Deflectors are located above the Cutterbar at each end. These Deflectors prevent forage stems from moving around the ends of the Knives. The bottom Deflector edges should be set down against the Cutterbar and the curved rear edges should be positioned about 1/32 to 1/16I (0.8 to 1.6 mm) from the Knives.

After the Screen is installed or after the Knives are sharpened, the Screen MUST be properly adjusted so that harvesting capacity is NOT decreased or so that

To adjust the Deflectors, loosen the two 3/8I Hexagon Head Cap Screws which are threaded into the Deflectors. Move the Deflector by tapping the 3/8I Screws.

CHAPTER 8 LUBRICATION GENERAL INFORMATION

CAUTION

1 2

NEVER attempt to lubricate this unit when any part of the machine is in motion. ALWAYS BE SURE to exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8) BEFORE proceeding to lubricate this equipment.

It is important to apply sufficient oil and grease to prevent excessive part wear and early failure.

1 – Reverse Delay Switch 2 – Front Reservoir Breather Plug

TRANSMISSION LUBRICATION (Figs. 43 & 44)

Fig. 44

NOTE: Do NOT remove the Reverse Delay Switch; this Switch MUST be precisely set for proper operation of the ’’reverse engagement’’ cycle.

The lubricant level in both the Bevel Gearbox and Shifter Transmission should be checked after every 200 hours of operation and replenished, when necessary.

The Bevel Gearbox requires 7 U.S. Pints (3.3 liters) of SAE #140 EP Gear Lube. The Shifter Transmission has two oil reservoirs. The front reservoir requires 7 U.S. Pints (3.3 liters) of SAE 10W40 motor oil and is filled through the Breather Plug hole in the front of the Reverse Delay Switch, as shown.

The rear Reservoir requires 1 U.S. Pint (0.5 liter) of SAE 10W40 motor oil and is filled by removing the Plate on which the rear Reservoir Breather is mounted.

Fig. 45

Both the Bevel Gearbox and the Shifter Transmission should be checked occasionally for oil drips and dust accumulation around the Seals. Oil drips or dust accumulation indicates that the Seals are leaking. Oil which is tan in color and foams excessively indicates that it has water present. Unless rust spots appear inside the Housings, the fluid does NOT require replacement.

Chapter 8 – Lubrication

NOTE:

OILING

Do NOT overfill either assembly; only fill them to the bottom of their Level Plug holes.

Apply motor oil on all of the points listed at the intervals specified.

SPINNER GEARBOX

Lubricate Every 10 Hours (or Daily)

The Spinner Gearbox requires 1 U.S. Quart (1 liter) of lithium–base grease. The Gearbox is packed at the factory and requires NO further attention unless service is performed on the Gearbox requiring removal and replacement of the grease.

The Rotating Telescoping PTO Drive Guard

Lubricate Every 50 Hours Load Sensor Contact Pivot Points

NOTE: 1 U.S. Quart (1 liter) of lithium–base grease will fill about 1/2 of the Gearbox volume.

Overfilling the Gearbox will cause grease to be forced out around the Shafts and Bearings.

Blower Belt Idler Pivot Points Rear Feed Roll Guides (both sides) Knife Sharpener Guide Bearings (10 places)

Lubricate Every 100 Hours (or Annually)

DRIVE CHAINS Lubricate all Drive Chains every 6 to 8 hours of operation using a good grade of foaming aerosol lubricant such as NAPA Chain and Cable Lubricant.

This type of lubricant increases the life of the Chain 3 to 4 times over those lubricated at 8 hour intervals with new or used motor oil. The recommended method is to spray the entire length of Chain on the center of the Rollers. It is more effective to oil Chains after use, while they are still warm.

Drawbar Pivot Pin All Hinged–Cover Hinges Feed Roll Spring Strap Pivots (both sides) Feed Roll Stabilizer Pivots (both sides) Deflector Control Worm Bearings

HYDRAULIC CIRCUITS

NOTE: To minimize wear on the Sprockets, the Chains should be replaced after they become worn 3% longer than their original length or otherwise when the Tightener (where provided) has reached the end of its adjustment.

The Harvester is equipped with two hydraulically powered control systems; the Attachment Lift Cylinder/ Knife Sharpener system and the Drawbar Control system. BE SURE to check and maintain the tractor hydraulic fluid level in accordance with the total circuit requirements of your particular Harvester. Only the Knife Sharpener Hydraulic system is primed at the factory.

AMMONIA SILAGE ADDITIVE NOTE: Gehl Company does NOT recommend running ammonia silage additives through any part of the Harvester because of their damaging effects on Bearings.

GREASING NOTE: Grease all fittings on a prescribed basis, at the intervals of operation listed, before and after storing the unit, and as otherwise listed. Use a good grade of lithium–base grease.

If an ammonia silage additive must be added to the silage in the field, certain precautions MUST be taken.

It should only be introduced at the Blower in the top portion of the Blower Outlet, in order to keep the ammonia away from the Bearings. The ammonia will cause the oil–carrying substance of the grease to dissolve in the Bearings causing them to fail. Special grease MUST be used which can withstand the ammonia vapor effects. Two greases which stand–up fairly well in the presence of ammonia are Aero Shell #7 (by Shell Oil Co.) and Chevron SRI (by Chevron Oil Co.).

But, even these two greases will have to be replenished twice a day in those Bearings which are exposed to ammonia vapor.

Printed in U.S.A.

Wipe dirt from the fittings before greasing to prevent dirt from being forced into the Bearing or pivot. Replace any missing fittings when noticed. Force grease into the fitting until it comes out at the Bearing Seal or the Shaft.

To minimize dirt build–up, avoid excessive greasing.

NOTE:

In addition to the fittings, repack the Wheel Bearings at least once a year. Apply a coat of grease, at least twice each season, to Front Feed Roll Guides (both sides) and the Deflector Worm and Gear. Periodically, lubricate the Telescoping Drive Shaft and Tube.

NOTE: After the first 10 hours of operation following Rim Sheet assembly or replacement, the Take-up Nuts torque should be checked and readjusted to 40 ft-lb (54 Nm), as necessary

CHAINS & SPROCKETS Sprocket wear is most often caused by an excessively worn Chain. A Chain which has worn 3% (1.03 times the original length) should be removed and replaced.

Guide the end with the (3) holes between the Blower Side Sheets and the Outlet. Using a drift punch, align the holes in the Rim Sheet and Liner with the holes in the Outlet and tightly secure the three parts with (3 each) 5/16 x 1 Plow Bolts, Lock Washers and Nuts.

This Harvester is designed so that when the Chain Tightener reaches the limit of its adjustment, the Chain has reached a condition of maximum wear. To calculate the original Chain length, multiply the number of Links times 3/4” for a #60 Chain or, times 5/8” for a #50 Chain.

With the Rim Sheet assembly correctly aligned and using a rubber mallet, block of wood or lead hammer, tap along the Side Sheet edges of the Rim Sheet, starting at the Blower Outlet end, to properly seat the Blower Side Sheets into the Rim Sheet grooves.

11.

Reinstall the Takeup and, in an alternating manner, tighten two Nuts while striking against the Rim Sheet Beads to seat the Rim Sheet assembly.

Secure the Takeup Nuts with 40 ft–lb (54 Nm) of torque and tighten the Jam Nuts.

The type of system used in your tractor will be found in your tractor’s Operators Manual.

Open Center System Tractors

KNIFE (& CUTTERBAR) SHARPENING

NOTE: The Needle Valve is NOT used with this type of tractor and should be left wide open. If it has been closed-down for use on a Closed Center System tractor, open it (counterclockwise).

WARNING

To determine the tachometer setting at which the unit should always be operated, first, idle the tractor at low idle and engage the remote control lever, starting the Sharpener Motor. Increase the tractor RPM until the Motor cuts out. The Hydraulic Fuse has tripped at around 9 gpm. A tachometer reading of 100 RPM less than this cut-out value is the proper speed at which the Sharpener should be operated with this tractor.

Because the tractor engine will be running while the Knives or Cutterbar are being sharpened, BE SURE that the Telescoping PTO Drive Connection is removed from the tractor PTO shaft.

When you are ready to grind the Knives or Cutterbar, set the tractor throttle to this tachometer setting and engage the remote control lever.

NOTE:

To facilitate rotating the Cylinder Knives while sharpening them, BE SURE to suspend the Harvester Telescoping Drive with the Spring provided. In addition, make sure that the Electric Clutch is open.

Cold hydraulic oil can trip the fuse at your “normal” tachometer setting. BE SURE to run the Sharpener at lower than the rated speed, BEFORE starting to sharpen the Knives or Cutterbar, until the oil is warm. Once the oil is warmed-up, the Sharpener can be operated at the “normal” tachometer setting to grind.

General Information The Knife Sharpener is designed to operate with any tractor capable of delivering a continuous 8 gpm supply of oil at 1500 PSI (10500 Kpa). The hydraulic circuit is equipped with a Check Valve for the Knife Sharpener Motor which prevents running the Motor backwards.

Thus, hydraulic hose hook-up to the tractor has NO particular orientation except to establish which way the tractor Remote Control Lever has to be moved to run the Sharpener Motor. A Hydraulic Fuse is included in the pressure line. This Fuse allows NO more than 9 gpm to flow thru it. Quantities in excess of 9 gpm cause the Fuse to snap shut and stop the Motor, and thus prevent overspeeding the Grinding Stone. If the Fuse snaps shut, it can be reset. This is done by moving the tractor Remote Control Lever momentarily to the position opposite of the running position. Like an electric circuit, if everything is in order and the Motor will NOT turn, the Fuse is tripped-out and MUST be reset to restore Motor operation.

NOTE: DO NOT try to operate above this setting as it will cause frequent tripping-out of the Hydraulic Fuse.

Closed Center System Tractors The throttle will have no control over the gpm on these tractors.

1000 RPM on the tachometer will be a good spot to run while using the Needle Valve to control the oil flow.

To find the proper setting for your tractor, turn the Valve shut (full clockwise) and back it off 2 turns. Engage the remote control lever, to start the Sharpener Motor. Open the Needle Valve slowly until the Motor stops. The Hydraulic Fuse has tripped-out at 9 gpm. Close the Needle Valve 7/8 turn (clockwise) and gently lock it in place with the Jam Nut. Reset the Hydraulic Fuse. Now, the system is permanently set for operation with this Closed Center System tractor.

Since few tractors deliver the same quantity of oil (gpm) to the remote circuit and since the gpm determines the RPM of the Hydraulic Motor, the first use (and first use only) with any unproved tractor will require one of two settings to be determined. On Open Center System tractors, the throttle setting will determine the Sharpener Motor RPM while on Closed Center System tractors, the Needle Valve will determine the RPM and thus, require setting.

906623/CP1097

Most new tractors have a readily accessible flow control of their own and you may prefer to use it. Its setting would be accomplished in a manner similar to the one described above. A scribe mark on the dial of the control, below the ’’Trip-out’’ point, will make it easy to reset without trial and error if it is required to move the control for other operations. Remember, however, the Sharpener Needle Valve and the tractor control are 62

interdependent and, if the tractor system is used, then open the Needle Valve all the way.

On some tractors the remote control lever is either spring-loaded to neutral or will kick out under low hydraulic pressures. These levers will have to be tied, with wire or rope, to prevent undesired disengagement.

Preparation (Fig. 55) Open the Toolbox Lid and switch the Selector Valve to the Knife Sharpener circuit.

Unlatch the Sharpener Cover and tip it forward over the Feed Roll Housing. Remove the Spinner and Cylinder Covers. Clean crop and debris from the undersides of the Knives so the Lower Guide Rollers can operate smoothly. In addition, BE SURE that the top surface of the Sharpener Rails are also clean. Remove the Draw Rod from its storage position.

With the Carriage at the storage end of the Rails and using a gloved left hand, turn the Cylinder and draw the Carriage toward the Knife until the Knife is caught between the two sets of Roller Guides under the Stone.

One set of Rollers bears-down against the top side of the Knife while the other set of Rollers bears-up against the bottom side of the Knife. A curved ’’lead-on’’ Plate is also provided to help rotate the Knife into position between the Roller Guides. Lower the Stone until it just contacts the Knife. Move the Carriage all the way across the Knife to make sure that it travels freely. Then, return the Carriage to the ’’storage’’ side of the Rails.

Start the Sharpener with the tractor remote control lever and make the first pass with the Stone set according to the information in the preceding paragraph. Make one pass each way on each Knife. Use a 1/8 turn of the Stone Adjustment Knob for each new cut but only after all Knives have been ground with the same number of passes at the previous setting. Totally grinding one Knife at a time will produce cutting edges at various radii which will make a close Cutterbar setting to all of the Knives impossible.

shown. To renew the cutting edge, the Cutterbar is sharpened so that it parallels the crop sliding over it.

1 3

2

After making a complete circuit of all the Knives with one Stone setting, the Stone itself will have worn away.

This means that the last Knife of the circuit will NOT be ground-down quite as much as the first Knife in the circuit. A good technique for overcoming this problem is to start the second circuit on the last Knife to be ground on the first circuit, i.e. after finishing the last Knife, turn the Stone down 1/8 turn of the Knob and begin grinding on this same Knife to start the next circuit. This Knife now becomes the first Knife on the new circuit and you should then stop and start this time on what was the second to the last Knife on the first circuit. Thus the starting point will work its way around the Cylinder with each succeeding pass. A chalk mark identifying each starting Knife as it comes up will help you to keep yourself straight.

To set-up the Cutterbar for sharpening, proceed as follows:

NOTE:

1.

Place the Sharpener Carriage in ’’storage’’ position at the left side of the Cylinder.

2.

Raise the Stone approximately 3/4” (19 mm) higher than the setting used for Knife sharpening.

3.

Loosen the 1/2” Nut which secures the Elevator so that it is free to move up or down in the slot. Remove the 3/8 x 3-3/4 Carriage Bolt from the right side. Then, place the Cutterbar into the location shown while orienting it in the same position and direction as it was when removed from the Harvester. When properly oriented, the edge to be sharpened will be closest to the Sharpener Stone.

With the Cutterbar correctly oriented, place the innermost of the two left side horizontal Cutterbar holes onto the stub of the Cutterbar Elevator.

4.

While holding the right end of the Cutterbar approximately 2” (51 mm) above the Support as shown, pull the Sharpener Carriage to a position where the Stop Plate on the Carriage is to the right of the Elevator. Make sure one of the Cylinder Knives is in place between the Roller Guides.

5.

Lay the Cutterbar on the right side Support and reinstall the 3/8 x 3-3/4 Carriage Bolt and tighten the Nut until the Cutterbar is lifted clear of the Cylinder Knives on the left side.

Traverse the Carriage in a smooth movement across the entire length of the Knife to prevent burning and to insure a smooth, uniform grind.

Cutterbar Sharpening (Figs. 57, 58, 59 & 60 & see Fig. 49) A Cutterbar (Shear Bar) does NOT need sharpening just because it is worn but rather, because it becomes improperly worn. The Gehl Company manufactures its Cutterbar so that, if it is set up close to sharp Knives, it will wear ’’sharp’’ and ’’parallel’’ to the crop sliding across it. This is shown in the illustration provided.

As long as the tungsten carbide facing provides a nice sharp lip to the cutting edge of the worn corner, the Cutterbar is as good as ’’brand new’’ (even better than ’’brand new’’).

If the Cutterbar wears improperly, as shown, where NO sharp edge exists to act as a scissor blade for the Cylinder Knives, the Knife Sharpener can be used to renew the Cutterbar edge.

To understand the function of the Sharpener, realize that the Cutterbar is set at an angle to the incoming crop as

6.

Move the Carriage over to the right end of the Rails (raise the Stone some more if necessary) and make sure that one of the Cylinder Knives is in place between the Roller Guides.

7.

With the Carriage positioned over the right end of the Cutterbar, lower the Stone to a distance of approximately 1/16” (1.5 mm) from the Cutterbar.

8.

With a 1/16” distance established on the right side, move the Carriage to the left end of the Cutterbar.

11.

Move the Carriage to the center of the Cutterbar and eliminate any downward bow to the Cutterbar (if present) by further tightening the 3/8 Nut on the Carriage Bolt until the center of the Cutterbar is at the same 1/16” distance from the Stone as the two ends were.

2

NOTE:

BE SURE that the Carriage is moved over only as far as the Stop Plate will allow. The Stop Plate prevents the Cutterbar from being ground too far to the left end which would result in removing a surface which is contacted by the Adjustment Cam. BE SURE that the Carriage Stop Plate is on the Cylinder Knife side of the Plate which is attached to the Cutterbar Elevator Mechanism or it will NOT be possible to draw the Stone Carriage across the Knives after the left side is set.

Start the Sharpener Motor and lower the Stone into contact with the Cutterbar until sparks appear.

Take the full stroke on each pass across the Cutterbar and crank the Stone down about 1/8 turn after each pass. Continue to make passes across the Cutterbar until NO roundness remains on the cutting edge and until the Tungsten Carbide-facing meets the cutting edge all the way across the entire length of the Cutterbar. It is NOT essential that the ground-down bevel be absolutely straight. However, if the Cutterbar setting was NOT made exactly correct, the bevel can always be adjusted by running the Stone across the least ground portion of the Cutterbar until the bevel is ’’true’’.

Chapter 9 – Service

Sharpener Adjustments 13.

14.

Do NOT grind any more than is necessary to restore the sharp edge and do NOT grind more than halfway down. This could cause the Cutterbar to become too weak to support the cutting load.

Stone Angle (Figs. 61 & 62 & see Fig. 56) The Knife Sharpener has a limited adjustment to provide the correct Knife Heel-to-Cutterbar clearance.

We recommend that, for the highest quality cut and the longest lasting Knife edges, the Stone be set to provide a clearance of 1/32″ and 1/16″ between the Heel of the Knives (trailing edge of the beveled surface) and the Cutterbar. This is the factory setting. So that you may check this clearance, a Template has been included with the Sharpener and stored in the Toolbox. The drawing provided shows how it is used and what to look for.

Sufficient grinding will remove all of the notch in the cutting edge on the right end of the Cutterbar.

This notch acts as a lead-in for the tilted Knives preventing the pointed leading edge of the Knife from driving into the top of the Cutterbar.

NOTE:

Always restore the notch on the right end of the Cutterbar (when it has been removed by the Sharpening Stone) before attempting to reinstall and adjust the Cutterbar. Use a benchmounted grinder to restore the notch.

Lay the Template across the cutting edges of any two ground Knives and parallel to the Cylinder Side Sheets.

Check the gap between the ground surface and the Template. Best performance will be obtained if the gap on a fully ground Knife measures from 1/32 to 1/16″.

The bevel on a new, unground Knife will measure about 1/16″. Grinding with the factory setting might produce two bevels until the original bevel has been removed.

Loosen the Locking Nuts on the Bolts which attach the front and rear Rails to their respective Posts. Then, using the Rail and appropriate sized allen wrench, rotate the Rail Attachment Carriage Bolt clockwise to obtain more clearance between the Rollers or counterclockwise to reduce the clearance between the Rail and Carriage Rollers. After the desired clearance is obtained, retighten the Locking Nuts.

Fig. 62

NOTE:

After the Roller Guide Block position is relocated, the Upper Roller Spring tension MUST be readjusted.

Guide Arm & Roller Adjustment (Fig. 62) The only requirement for adjustment of the Roller Guide Arm is that both of the Rollers MUST be touching the Knife when both are positioned below the Knife. To get both Rollers to touch, loosen the Front Guide Block Bolt and rotate the Roller Guide assembly. If both Rollers are NOT made to touch the Knife, a jump will be made in the surface of the sharpened Knife when one or the other of the Rollers leaves the Knife, at the end of the stroke, allowing the other Roller to become the guide.

Spring Plate, Spring & Upper Roller Adjustments (See Fig. 56) The Upper Roller tension for both Rollers MUST be reset whenever the Lower Roller Guide Block is repositioned. Begin by positioning the Sharpener Carriage at the point on the Rails where the Right Upper Roller is next to (but NOT on) the right end of one of the Knives. Loosen the Adjustment Bolt so that all Spring tension against it is released. Next, move the Spring assembly up or down in its slots to bring the bottom of the Roller flush with the bottom side of the Knife. After tightening the Bolts in the slot, tighten the Adjustment Bolt until the bottom of the Roller is approximately 1/16” (1.5 mm) below the top surface of the Knife.

Lastly, retighten the Locking Nut to fix the Roller position. Repeat this same procedure for the Left Roller on the left end of the same Knife.

Rail Alignment (Fig. 56) To check Rail alignment, first position the Sharpener Stone over the left corner of a Knife. Using the Motor Position Adjustment Knob, adjust the Stone position for a measured gap of 1/8” (3 mm) from the Knife and position it over the right corner of the Knife.

Sharpener Carriage Removal (See Fig. 59)

SPINNER (Fig. 65 & see Fig. 53)

It may be desirable to remove the Sharpener Carriage from the Rails to facilitate Stone replacement. To remove the Carriage, first temporarily remove and retain the Stop Plate which is secured with (2 each) Carriage Bolts and Lock Nuts. With the Stop Plate removed, the Sharpener Carriage can be guided-off the right end of the Rails.

The Spinner is linked by a direct Chain drive to a Sprocket on the end of the Cutting Cylinder Shaft. When the Drive Chain is uncoupled and removed, the Spinner should be free to rotate (by hand). To release the Spinner Drive Chain Idler tension, perform the following steps.

While holding-up on the Latch, force the Idler Sprocket Yoke down until a hole (in the Tube) appears below the Latch. Then, insert a 1/8” diameter pin (such as a nail) thru the hole in the Tube to retain the Yoke in that position. Then, the Drive Chain can be uncoupled and removed.

REMOTE GREASE LINES Several Remote Grease Lines are provided on the Harvester to facilitate lubrication of otherwise difficult to reach relubeable Bearings. If a Remote Grease Line is damaged or broken, it can be replaced by ordering a Tubing Kit (Gehl #065185).

Procedures for Grease Line replacement are covered in Instructions packaged with the Kit.

TELESCOPING PTO DRIVE

Disc & Paddles

NEVER attempt to mix the halves of a 1-3/8 Drive with the halves of a 1-3/4 Drive. Each of the halves of the two Drive assemblies are manufactured to different lengths which if mixed, could cause the Drive to separate while it is turning and thus prove to be very hazardous.

WARNING

To remove the Spinner Disc, Paddles and Hub, proceed as follows: 1.

Detach and remove the Spinner Cover.

2.

Remove the Spinner Disc assembly, by removing the two 5/16 x 1–1/4 Grade 8 Screws attaching the Disc assembly to the Spinner Hub. Then lift the Disc away from the Hub or remove the Cap Screw from the top end of the Vertical Shaft and lift the Hub and Disc assembly off the Vertical Shaft.

3.

NOTE: Besides the personal hazard of intermixing 1-3/8 and 1-3/4 Drive halves, the consequence of incompatible operation of the two improper halves could cause permanent damage to the Drives. To prevent mixing Drive halves, the Male and Female splines and the Rotating Guards on 1-3/4 Drives are manufactured opposite those on 1-3/8 Drives.

To remove each Paddle from the Disc, remove the (2) fasteners from each Paddle.

ELECTRIC CONTROLS (Figs. 67, 68 & 69) The Control Box is located on the tractor and is linked to the Feed Roll Drive and the Deflector and Cap Gearmotors through Wiring Harnesses with Plug Connectors. Refer to the Wiring Diagrams, provided at the end of this chapter, for circuit wiring and troubleshooting references.

BE SURE the Rim is clean and free of rust.

Lubricate both the tire beads and rim flanges with a soap solution. Do NOT use oil or grease. Do NOT weld, braze, or otherwise attempt to repair and use a damaged rim.

Voltage Checks To determine if the Electrical System is in proper operating condition, perform the following D.C. voltage checks:

Use a clip-on tire chuck with a remote hose and gauge which allows you to stand clear of the tire while inflating it.

CAUTION

NEVER inflate beyond 35 PSI (240 kPa) to seat the beads. If beads have NOT seated by the time the pressure reaches 35 PSI, deflate the assembly, reposition the tire on the rim, relubricate both parts and re-inflate it. Inflation pressure beyond 35 PSI with unseated beads may break the bead or rim with explosive force sufficient to cause fatal or serious injury.

BEFORE proceeding, remove the Telescoping PTO Drive Coupling from the tractor PTO shaft.

With the Control Box attached to the tractor battery, the tractor connected to the Harvester and the Telescoping Drive disconnected, start the tractor engine and take the following readings while operating the Control Box Switches in the ’’Reverse’’ mode.

After seating the beads, adjust the inflation pressure to the recommended operating pressure listed.

NOTE: The Circuit Breaker, in the Control Box, will trip-out when the Hold–for–Reverse Switch is held on for approximately 12 seconds.

Test #1 - Battery voltage MUST be 12 to 15-1/2 volts

Check the Forage Harvester Tire pressure after every 50 hours of operation. Tires should be inflated to appropriate pressure listed in the table. Wheel bolt torques should also be checked after every 50 hours of operation and tightened with 90 ft-lb (124.5 N-m) torque.

CHAPTER 10 PREPARING FOR FIELD OPERATION TRACTOR HITCH ALIGNMENT (Figs. 70 & 71)

The front to rear position of the tractor drawbar hitch hole centerline MUST be correct to insure the proper Universal Joint relationship. The tractor drawbar hole should be 16″ (405 mm) from the rear of the 1-3/8 diameter 1000 RPM tractor PTO Shaft, or 20″ (508 mm) from the rear of the 1-3/4 diameter 1000 RPM tractor PTO Shaft.

Position the tractor drawbar hitch hole centerline directly in-line with the tractor PTO Drive Shaft, and secure so as to eliminate any side to side movement of the tractor drawbar. If the tractor drawbar can NOT be positioned in-line, position it toward the left, as close as possible to the centerline of the PTO shaft. It is important to use the 1″ dia. Hitchpin furnished with the Harvester to help center the Harvester Hitch pole with the tractor drawbar and reduce the amount of side to side movement. Keeping the drawbar in-line and minimizing side to side movement is essential in eliminating drive-line vibration, especially when maneuvering corners.

DRIVE LINE ALIGNMENT (Fig. 72)

PREPARING HARVESTER

After the Harvester Hitch Clips and Telescoping Drive are connected to the tractor, the Front Bearing Support should be raised or lowered to place the Fixed-length (Main Drive) and Telescoping Drive Shafts in a straight line (when viewed from the side). The straight-line alignment extends joint life by reducing joint vibrations.

To raise or lower Front Bearing Support, temporarily remove the Side Shields on the Front Bearing Stand and remove the (2 each) 3/8 x 5-1/2 Cap Screws and Plain Washers which are securing the Front Bearing Support to the Bearing Support Stand. Next, reposition Bearing Support so that both Shafts are in a straight line. After correct alignment is obtained, line-up the holes in the Bearing Support with appropriate pairs of holes and slots in each side of the Support Stand.

The following points of preparation will have to be made on the Harvester with respect to the Attachment being mounted. Refer to the Adjustments chapter of this manual and, if necessary, the appropriate Attachment Operator’s Manual for specific adjustment details and requirements.

GEHL Company complies with all laws for safety when transporting slow–moving vehicles on public highways. The Harvester is equipped with a Bracket for mounting a Slow–moving Vehicle Emblem (SMV) on the Rear Left Guard. Red Reflector Strips are also provided on the rear corners or the Harvester.

CAUTION

NOTE: Slow–moving Vehicle Emblem MUST be purchased locally.

ALWAYS follow state and local regulation regarding use of a safety chain and transport lighting when towing farm equipment on public highways. ONLY a safety chain (NOT an elastic or nylon/plastic tow strap) should be used to retain the connection between the towing and towed machines, in the event of separation of the primary attaching system.

BE SURE to check with local law enforcement agencies for your own particular regulations.

Unless otherwise prohibited, use a Slow– moving Vehicle Emblem.

Because of the variations in the Safety Laws for different states and localities, it may be necessary to change the Emblem Bracket mounting location. Your GEHL dealer can assist you in relocating the Bracket, if necessary.

TOWING ON HIGHWAY(Fig. 78)

WARNING Good safety practice dictates that you NEVER tow an implement (without brakes) unless the towing vehicle weighs at least one-and-one half (1-1/2) times the weight of the towed implement and its load. For any public highway travel and to be in compliance with this rule, BE SURE that your tractor is heavy enough to counterbalance the weight of the Harvester and loaded wagon. Do NOT tow a loaded wagon behind the Harvester on a highway unless the wagon has operational brakes.

Chapter 14 – Set-up & Assembly

NOTE:

Check that the Deflector is NOT binding before proceeding. If necessary, readjust the Clamps and Spacers. At this time also, adjust the Tripod Brace and Arm (where applicable), to find the proper alignment for the Deflector (and Tripod) which best enables turning the Deflector with the least amount of resistance.

Mount the Angle Bracket to the side of the Deflector (or Horizontal Extension) using the hole provided. Secure the angle with a 5/16 x 3/4 CS, L and N. Place the head of the CS inside the Deflector.

Temporarily remove the rear 1/2 N, L and (1 of 2) P from the middle of the left side of the Deflector. then, install a Pulley onto the smaller end of an S–Hook and squeeze the S–Hook shut. Install the larger end of the S–Hook over the 1/2 CB and replace the P, L and N. The S–Hook should be between the two (2) P. Form another S–Hook and Pulley assembly and install this onto the Cap. BE SURE to secure the S–Hook to the Cap and Pulley by squeezing the ends shut.

For a horizontally extended Deflector application, temporarily remove the LN from the 5/16 x 1–1/2 THMS above the Deflector Brace on the left side. Then, place an S–Hook and Pulley assembly over the THMS and reinstall the LN; make sure the S–Hook pivots freely when the LN is tightened.

Insert the Cap Control Cable (Wire Rope) into the hole in the Cap Gearmotor Spool, from the outside of Flange, into the middle of the Spool (Fig. 91). Then, route the end of the Wire Rope up through the Pulleys and back to the S–Hook on the Angle Bracket as shown (Fig. 92).

Form a loop over the end of the S–Hook and install a Wire Rope Clamp to secure the loop to the S–Hook.

Cut–off any excess Cable, extending beyond the Cable Clamp.

NOTE: The Wire Rope should be cut to length so there are NO wraps around the Spool when the Cap is in the raised position. Any wrapping on the Spool, when the Cap is ”up”, will uncoil and the Cable will jump–off of the Spool.

Step 8: Implement Wiring Harness (See Figs. 87 & 88) The Main Implement Wiring Harness is the electrical connection between the tractor–mounted Control Box and the Harvester–mounted electrical components. The following information describes routing the Harness, making the appropriate Plug connections and Clamp locations for the Wiring Harness and Power Leads.

Refer to the Wiring Diagrams provided in the Service chapter for additional identifications and proceed as follows:

NOTE:

When routing the Main Wiring Harness or the Hydraulic Hoses inside the Hose Side Cover, the Drawbar should be swung–out to the maximum left position to assure that an ample amount of Harness and Hoses is available at the back end of the Drive Line.

Begin by routing the Main Wiring Harness inside the Hose Side Cover on the side of the Main Drive Line.

Pass the Connector directly underneath the sloped portion of the Front Bearing Stand. Allow enough Harness to extend to the tractor–mounted Connector, while keeping the Harness above the Telescoping PTO Drive.

The Wiring Harness should be routed on the right side of the Stand. Install two (2) 1–1/4 size Wire Clamps around the Harness and fasten it to the top inside surface of the Front Bearing Stand with (2 each) 5/16 x 1 CB–SN, 1 and N.

Chapter 14 – Set-up & Assembly

NOTE:

2.

Do NOT install any Hoses between the top of the Harness and the underneath slope of the Front Bearing Stand. The weight of the Hoses could damage the Wire Harness. In addition, do NOT clamp the Implement Wiring Harness to any portion of the tractor. This will surely damage the Harness if the tractor moves away from a parked Harvester with the Wiring Harness still attached.

ONLY use the electrical Connector to attach the Implement Harness to the Tractor Connector. The Connector has a ”Breakaway” feature to prevent damage. For additional details, refer to the Control Box & Wiring Harness Mounting step at the end of this chapter.

Make the proper Red (+) and White (–) ring Terminal Power Supply Harness connections to the tractor battery or starter. The Harvester controls will NOT always operate as desired, if the Control Box wires are attached anywhere else except at the batter or tractor starter connections. The battery MUST provide 12 volts D.C. The tractor MUST have a negative (–) ground. Route the Harness Plug to the Control Box.

Step 9: Control Box Mounting & Wiring (Figs. 94 & 95) Refer to Fig. 94 for a typical installation of a Control Box. Use your own judgement to select a conveniently reached mounting location on your particular tractor.

Proceed as follows: 1.

Select the desired Control Box mounting location in the tractor cab or on the fender. Using the Spade Mounting Bracket as a template, locate and drill the two 9/32” diameter holes. Then, secure the Bracket with (2 each) 1/4 x 1 CS, P, L and N. Place the second Spade Mounting Bracket into the Receptacle on the back of the Box and temporarily install the Box onto the other attached Bracket in order to locate the two additional 9/32” diameter holes. Then, remove the Box, drill the holes and attach the second Spade Mounting Bracket.

NOTE:

The two Spade Mounting Brackets can be bent, drilled, or otherwise modified to fit the tractor, a required.

CAUTION Make sure to avoid sharp metal corners or objects and pinch points along the path of the Harness which could cause insulation break down and a short–circuit.

9.

Unless the Harvester is being equipped with only a Horizontal Extension and NO Vertical Extensions, the Tripod Arm can always be positioned as shown and attached to the Vertical Tripod Pipe or Tripod Extension with the (4) Lock Screws in the appropriate position for correct alignment with the Deflector Bracket. For only those situations where the Harvester is just equipped with a Horizontal Extension, turn the Tripod Arm upside down to enable aligning it with the Deflector Bracket.

The CB1260 Harvester is provided with a factory– installed, 1–ft Vertical Extension. This allows the Capmotor and Deflector Control Motors to be factory installed and pre–wired. When a 1–ft and/or 2–ft Vertical Extension is being installed, the additional Vertical Extension(s) should be mounted above the factory–installed 1–ft Vertical Extension. This will keep the Cap Motor and its wiring close to the Blower.

A set of (8 each) 1/2 x 1–1/4 CS and LN is provided with each Extension for attaching that Extension.

NOTE:

The following information can only be carried–out after the Deflector is in position to be installed and secured onto the Blower Outlet.

With all nine Knives installed, the Length–of– Cut can typically be increased to 1/2”. As shown in Fig. 103, the original 28T Sprocket is replaced by a 20T Sprocket. Similarly and as shown in Fig. 104, the original 40T Sprocket is replaced by a 28T Sprocket.

Both Sprockets are secured to their respective Shafts with two SHSS each. The Input Chain to the Shifter Transmission and the Chain driving the Attachment Drive Torque Sensor will have to be shortened to fit the new Sprockets.
