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.

BEFORE YOU ATTEMPT TO OPERATE THIS EQUIPMENT, READ AND STUDY THE FOLLOW­ ING 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. How­ ever, 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 offurther danger and should be read and observed closely.

The word DANGER, WARNING or CAUTION, used herein and on the machine itself, signals three degrees of hazard, as follows.

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

1.

Disengage the tractor PTO.

2.

Shut off the tractor engine, remove the starter key and take it with you.

3.

Wait for all movement to stop.

4.

Remove the Telescoping PTO Drive and ALL power connections from the tractor.

ONL Y 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.

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

ALWAYS wear safety glasses with side shields when strik­ ing 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.

ALWAYS follow state and local regulations regarding use of a safety chain and auxiliary lighting when towing farm equipment on public highways. BE SURE to check with local law enforcement agencies for your own particular regulations.

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

Good safety practice dictates that you NEVER tow an implement (without brakes), unless 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

SAFETY your tractor is heavy enough to counterbalance the weight of the Baler and a full-sized bale.

NEVER tow a Baler on a public highway ata speed greater than 20 mph (32 kmh). Unless otherwise prohibited, use a Slow-moving Vehicle Emblem.

BE SURE that the Telescoping PTO Drive rotates freely inside the Drive Shield Tubes at all times. Balers are provided with two different types of Telescoping Drives; one Drive has Metal Shield Tubes and the other has Plastic Shield Tubes. The Drive with Plastic Shield Tubes MUST be anchored to a hole in a part of the Baler Frame with the Tie-down Chain provided. The Drive with Metal Shield Tubes MUST NOT be anchored.

Bales made with the Round Baler are LARGE, CYLINDRI­ CAL and HEAVY. Serious personal injury or property damage could result if the Bales are NOT carefully and properly handled. NEVER eject or store Bales where they could possibly roll downhill.

Our Company does NOT sell replacement tires. In addition, tire mounting, service or inflation can be dangerous. When­ ever possible, trained personnel should be called to service and/or mount tires, following the tire manufacturer's in­ struction. If you do NOT have such instructions, contact your tire dealer or our Company. In any event, to avoid possible fatal or serious injury, follow the specific directive given in the Service chapter of this manual.

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. .

BE SURE to review and comply with ALL Safety recom­ mendations set forth in the tractor operator's manual.

PRESSURE GAUGE (See Fig. 5-6) The Baler is provided with a Pressure Gauge to indi­ cate bale forming pressure. Refer to the Operation chapter in this manual for detailed information regard­ ing the use of the Pressure Gauge.

A CAUTION NEVER allow bale forming pressure to exceed 3200 PSIG. Baling at higher pressures will cause unnecessary strain and premature wear on the Baler and tractor Drive components.

BE SURE that the Telescoping PTO Locking Devices are properly secured to both the trac­ tor PTO shaft and the Baler Input Drive Shaft BEFORE starting the tractor engine. Also, make sure the PTO Drive Shield Tubes are free to rotate.

NOTE:

When transporting the Baler, remove the Telescoping PTO Drive from the Baler and store it in or on the towing vehicle.

PRESSURE CONTROL VALVE (See Fig. 5-1) The Baler is provided with a Pressure Control (Relief) Valve to limit the hydraulic system pressure to 3400 PSIG. This Valve, located on the front of the Baler, will allow the Rear Door to open (and thereby relieve pressure), if too much material is fed into the baler.

A CAUTION If the pressure, as Indicated on the Pressure Gauge, exceeds 3400 PSIG, replacement of the Pressure Control Valve may be required.

SAFETY CHAIN & AUXILIARY LIGHTING (Fig. 5-8)

A CAUTION ALWAYS follow state and local regul ations regarding a safety chain and auxiliary lighting when towing farm equipment on a public high­ way! BE SURE to check with local law enfor­ cement agencies for your own particul ar 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 machine, in the event of separation of the primary attaching system.

As required or when desired, the Baler should be equipped with a safety chain and auxiliary lighting for transporting the unit on public highways. The chain should be routed as shown in the illustration . Refer to the Optional Features & Accessories Chapter for order­ ing information. If auxiliary lighting is required or desired, it must be purchased locally.

FIRE EXTINGUISHER

A WARNING If a fire should break out: Eject the bale from the Baler IMMEDIATELY, move the Baler up­ wind 30 feet or more (from the ejected bale), shut the tractor engine off and proceed to put the fire out with a fire extinguisher.

There is always the possibility of fire when handling dry forage materials. GEHL Company recommends that, to limit the damage to the Baler and/or tractor in case of a bale fire, at least a five gallon, pressurized water type, fire extinguisher should be mounted on the tractor or Baler.

NOTE: A five gallon extinguisher should be suffi­ cient to put out small fires that are burning the dry material that remains on the Baler, after the bale is ejected. This size extinguisher, however, is insufficient to put out even a small fire in the bale.

A CAUTION The pressurized water fire extinguisher DOES NOT replace the dry chemical fire extin­ guisher on the tractor (If so equipped). NEVER use a water type fire extinguisher on electrical or fuel fires.

A CAUTION To reduce the possibility of a fire, make it a point to keep crop material build-up to a min­ Imum, especially on the Roller ends, the Chain Drives (behind the left Side Doors) and In the Pickup Drive area.

FUNCTIONAL DESCRIPTIONS

General (Fig. 6-1) Crop material is picked off the ground by the Four­ Tinebar floating Pickup and fed directly in to the Baling Chamber. Chain-driven Rollers, located inside the Baling Chamber, roll and tumble the incoming crop into a round bale. Just before the bale reaches its final size, additional crop is fed into the Baling Chamber creating a bale with a medium density core and a hard outer shell. The hard outer shell helps to reduce set­ tling and provides better weather resistance. Once the proper baling pressure is reached (as indicated by the RED area on the Pressure Gauge) the bale can be

Transmission of Mechanical Power The minimum tractor power required to operate the Baler is 70 hp. The Baler Drawbar is vertically adjus­ table and MUST be properly connected to the tractor per details in the Preparing For Field Operations chap­ ter. Mechanical power is transmitted from the tractor PTO, through a Telescoping PTO Driveline, a Right­ angle Drive Gearbox, a Rubber Coupling, a Jackshaft, to the Main Drive Sprockets and Chain. The power is then transmitted by Chains and Sprockets to the (20) Rollers and the Pickup Assembly.

Density Control (Fig. 6-2)

Twine Tie Systems

Bale density is monitored by a Hydraulic Pressure Gauge which is located on the right front of the Baler.

As the bale increases in size, it exerts more and more pressure on the Rear Door. The Rear Door is held closed by hydraulic pressure, supplied by the tractor to the Rear Door Cylinders. Since the Pressure Gauge is tapped directly into Rear Door hydraulic system, the Gauge indicates the amount of pressure required to keep the Door closed. Therefore, the Pressure Gauge is used as a guide to regulate bale density and, also, to indicate when to wrap and eject the bale.

The Manual-Electric and Auto-Electric Twine Tie Sys­ tems share many of the same components with the main exception being the Control Box, Switches and inter­ related wiring.

NOTE:

On units equipped with an Auto-Electric Twine Tie system, a Pressure Switch is also tapped into the Rear Door hydraulic system and is therefore regulated by the amount of pressure exerted on the Rear Door Cylinders. Refer to the Twine Tie Systems Functional Description later in this chapter.

B---:----­

In the manual system, control of the Electric Actuator (which, in turn, moves the Twine Tubes from side to side) is performed by the operator by toggling a Switch on the remote mounted Control Box. This feature is also available on the Auto-Electric system but, only while in MANUAL operating mode. In the Auto­ Electric Tie system (when operating in the "AUTO" mode) the entire wrapping and twine cutting operation is controlled automatically.

Also included only in the Auto-Electric system is a Pressure Switch which activates the bale wrapping sequence when hydraulic pressure on the Rear Door Cylinders reaches a predetermined value (the Pressure Switch also activates an Alarm which signals the operator that the wrapping cycle has begun). In the Manual-Electric system, the operator must watch the Pressure Gauge and when it is at the required pressure, the operator must manually start the wrapping cycle.

(Refer to the Density Control topic earlier in this chap­ ter for additional information regarding the Pressure Gauge.)

Manual-Electric Control The Manual-Electric Twine Tie System Control Box is provided with a single Switch which functions as fol­ lows: Extend/Retract Switch on Control Box

A. B. C. D.

Starting pressure (1000 to 2400 PSIG or more) Bale forming pressure (1000 PSIG minimum) Final pressure in dry brittle materials (3000 PSIG maximum) Final pressure in normal damp materials (3200 PSIG maximum)

NOTE:

GREEN Area = 1000 to 2000 PSIG RED Area = 2600 to 3200 PSIG

This Switch is a three-position, momentary contact, toggle-type Switch which returns to the "off" position when released. This Switch is provided to allow the operator to extend and retract the Electric Actuator, as necessary, for wrapping the bale with twine.

Move the Toggle to the right (and hold it there) to extend the Actuator Rod which, in turn, will move the Twine Tubes to the left; move the Toggle to the left (and hold it there) to retract the Actuator Rod which, in turn, will move the Twine Tubes to the right.

Auto-Electric Control (Fig. 6-3) Fig. 6-2: Pressure Gauge

Transmission of Hydraulic Power Hydraulic fluid pressure MUST BE provided by the tractor hydraulics system. The tractor's auxiliary con­ trol valve and remote control circuit are used to ac­ tivate the Rear Door Cylinders (for raising and closing the Rear Door) and for holding the Rear Door closed during baling.

22

The Auto-Electric Twine Tie System Control Box is provided with various components which function as follows: Auto/Off/Manual Switch AUTO position - provides automatic operation of the wrapping System when the RECYCLE Button is pressed.

OFF position - disconnects electrical power to the Control Box (turns the Auto-Electric Twine Tie Sys­ tem "Off") MANUAL position - provides for manual operation of the Actuator (enables the EXTEND/RETRACT Switch) End-wrap Control Turn the Knob on this Control clockwise to increase the number of twine wraps on the bale ends or counterclockwise to decrease the number of twine wraps on the bale ends.

Center-wrap Control Turn the Knob on this Control counterclockwise to increase the number of twine wraps across the bale or clockwise to decrease the number of twine wraps across the bale.

Extend/Retract Switch This Switch is enabled ONLY when the AUTO/OFF/MANUAL Switch is in the MANUAL position and is a momentary contact, toggle-type Switch which returns to the "off" position when released. This Switch is provided to allow the operator to manually extend and retract the Electric Actuator, when desired, and thereby override automatic control of the Actuator.

If the manual override is used and/or the automatic cycle is interrupted, the Actuator will return automat­ ically to the fully extended position (and continue to cycle) when the RECYCLE Button is pushed.

Recycle (Pushbutton) Switch This Switch is a momentary contact, pushbutton-type Switch which "starts" the wrapping cycle when pressed and returns to a "deactivated" position when released.

If it is desired to wrap the bale BEFORE the Bale Size Sensor Switch activates the automatic cycle, push and release the RECYCLE Switch Button; this will activate the System and automatically execute one wrapping cycle.

Horn The Horn is provided to inform the operator that the bale has reached a predetermined size (determined by the setting of the Bale Pressure Sensor Switch) and that the wrapping cycle is about to begin. The Horn con­ tinues to sound until the Twine Tubes are in position and ready to feed twine into the bale chamber.

AL WAYS determine and correct the cause of the Breaker trip when resetting is required.

BALING TIPS The following information provides guidelines for using the Baler to get the most out of your crop and investment.

Preparing The Material For Baling The material, to be baled, can be prepared in a number of different ways, depending on the operator's preference and available equipment. Except for windrow size, a general rule to follow is to prepare the material the same way as you would for rectangular baling.

23

The most desirable bales result when the material is properly cut and conditioned and then formed into even, full, Pickup-width windrows.

Cutting the Crop Cut the crop as long as possible. Excessively dry, short, slippery and/or thin crops, as are sometimes encountered in certain grasses and straw, can be suc­ cessfully baled, providing that the material is of suffi­ cient length to hold the bale together. However, when baling crops such as these, difficulties in building Gauge pressure above 2500 PSIG and in wrapping the bale with tw ine at the end of baling cycle, may be experienced, regardless of cut crop length. Refer to the Baling topic, later in this chapter, for more details.

BALING

NOTE:

To avoid damaging the Baler Drive Line, slow tractor RPM to 1400 or less BEFORE engaging PTO. Then, engage PTO slowly. In addition, NEVER disengage PTO quickly with a full bale in the Chamber.

The mass of a rotating bale can cause a complete Drive Line reversal. When using a tractor equipped with a PTO brake mechanism, BE SURE to slow-down the engine speed BEFORE disengaging the PTO.

Use the following procedure as a guide for proper baling techniques.

1.

Conditi oning the Crop Over-conditioning the crop is NOT advisable, par­ ticularly if the bales are going to be stored outside, because excessive shattering of the stems will invite moisture absorption, which can lead to spoilage.

Under-co'n ditioning can also cause spoilage, par­ ticularly when baling cane-type crops and other heavy­ stemmed materials.

After transporting the Baler to the field. adjust the Pickup height according to crop conditions and ground contour. Refer to the Pickup Height and Pickup Flotation topics in the Adjustments chapter of this manual. for details.

NOTE: The Pickup Assembly MUST be carried up off of the ground at all times. Operating with the Pickup too low to the ground, will result in excessive Tine wear or breakage and possible damage to the Pickup Strip­ pers and Headers, Cams and Cam Bearings.

2.

Move the Baler into position with respect to the windrow. Start the PTO, bring the tractor RPM up to the desired operating speed and begin baling.

Windrowing the Crop

3.

Bales of consistently uniform size and density can best be produced by starting with windrows of proper size.

Windrows should be reasonably even in height and width. Windrows with high center crowns result in more material in the center of the bale, producing a bale with loose ends and making it more difficult to wrap the bale with twine.

Bale the driest crops first (usually the outside of the field) traveling in the same direction that the rake or windrower traveled so that the crop is picked up in a head-first position.

4.

When baling hay in full, Pickup-width windrows. the average operating speed of the tractor should be approximately 4 to 6 mph. At this speed, the Pickup will gather the windrow into the Baler with the least amount of crop agitation.

5.

When baling narrow windrows (30" or less). start forming the bale by driving down the center for approximately the first quarter of the bale. For the next quarter of the bale. weave back and forth across the windrow. so the crop is distributed evenly across the entire width of the Bale Cham­ ber. Discontinue the weaving pattern for the last one half of the bale and concentrate on feeding the material. alternately, into the sides of the Pickup. The bales that are formed in this manner, are more uniform than bales that are formed by continuously weaving, during the entire baling cycle.

NOTE: Proper conditioning can best be ac­ complished using either a self-propelled windrower or pUll-type mower conditioner.

If full, Pickup-width windrows (48"-66") cannot be produced. the crop should be formed into windrows of 30" or less. Windrows between 30" and 48" wide should be avoided because. as the Baler operator cros­ ses the windrow from side to side to crowd material into the ends of the Pickup. the center is being con­ tinuously fed and as a result, the bale will be barrel­ shaped with lower density at the ends and higher density at the center.

NOTE:

If windrows are generally wider than the Pickup width (greater than 66''), installation of a Crow­ der Wheels Kit is recommended. Refer to the Optional Features &Accessories chapterfor additional informa­ tion.

24

Unplugging

A DAN G ER DO NOT attempt to unplug the Pickup area while the PTO Is engaged. In addition, NEVER attempt to manually clear debris or foreign matter from any other part of the Baler, while It is running. Failure to heed, could result In death or serious bodily Injuryl ALWAYS exer­ cise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8) BEFORE attempting to unplug the Pickup or manually clear debris from It! If plugging occurs between the Pickup and Baling

Chamber and/or the Pickup Drive Clutch is slipping, STOP forward travel IMMEDIATELY and disengage the PTO. Then, reduce engine RPM and re-engage the PTO. This will normally clear the Pickup. If NOT, repeat this sequence, as necessary, to clear the plug. If repeating this sequence, several times, does NOT clear the plug, open the gate and eject the bale, because the ratchet clutch will NOT drive pick-up backwards. If the plug still does NOT clear, exercise the MAN­ DATORY SAFETY SHUTDOWN PROCEDURE (page 8) BEFORE leaving the tractor to remove the plug by hand.

When resuming Baler operation, adjust the ground travel speed; a slower speed may be required in heavy crops. In some conditions, it may also be necessary to remove one or both of the Springs on the Hay Hold­ down, to improve feeding. If plugging continues, check all of the Pickup Strippers to make sure that they are parallel and evenly spaced. Also, check the angle of the Baler to make sure that the Twinebox is parallel to the ground. If desired or as required, readjust the Hitch Plate to change the Baler angle so that the Twinebox is parallel to the ground or angled slightly to the rear. (Refer to the Preparing for Field Operation chapter for more details.)

NOTE:

Do NOT allow any stones or other debris to enter the Baler or damage to internal parts may result.

If a foreign object is seen entering the Baler, IMMEDI­ A TEL Y disengage the PTO to stop the Baler, open the Rear Door approximately 8" (or just enough to allow the object to pass through) and then slowly re-engage the PTO. After the object falls out, close the Rear Door and resume baling.

Using The Pressure Gauge For Density Control (See Fig. 6-2) In order to produce dense, uniform, 72-inch diameter bales, a minimum of 1000 PSIG of pressure MUST be maintained on the Rear Door, throughout the entire baling cycle. A Pressure Gauge is provided on the Baler to monitor the amount of pressure being applied to the Rear Door. Watch the Gauge as you are baling and maintain the pressure at 1000 to 2400 PSIG, (in the GREEN area or above), during the entire baling cycle.

As the bale starts reaching its final size and density, the pressure will increase from its previous (more sta­ bilized) indication. When the Gauge Indicator reaches 2600 to 3200 PSIG, (the RED area), the bale is formed and ready for wrapping with twine.

NOTE: In some dry and/or brittle materials, it may NOT be possible to reach the final bale pressure (the RED area on the Pressure Gauge).

A CAUTION NEVER allow the baling pressure to exceed 3200 PSIG (above the RED area on the Pres­ sure Gauge). Baling at too high a pressure places excessive strain on the entire Baler and can cause Drive Chain failure.

Wrapping Bale With Twine (Fig. 6-4 & See Fig. 6-2) The bale can be wrapped with twine any time after the mass of material in the Bale Chamber starts rolling.

Usually, the bale should be wrapped only after the Pressure Gauge Indicator is in the RED area (2600 to 3200 PSIG). Refer to "Using The Pressure Gauge For Density Control" topic above, for details regarding baling pressures.

NOTE: The following procedure is the MANUAL sequence which is accomplished automatically by the Auto-Electric Tie system and activated automatically by a Pressure Switch. The entire process of wrapping the bale with twine is done from the tractor seat.

The position of the Needle on the Hydraulic Pressure Gauge can be used as a fairly accurate guide for deter­ mining when to stop baling and start wrapping the bale with twine. When the desired pressure is reached, stop Baler forward travel. Then, using the Toggle Switch on the Control Box, activate the Actuator to position the Twine Tubes so they are centered and vertical.

25

NOTE: By moving the Twine Tubes to the middle of the Baler, appropriate lengths of twine are brought out for starting to wrap a new bale.

Next, drive forward again to take in a small amount of material to help start feeding the twine into the Baler.

A DANGER NEVER attempt to manually feed twine or material into the Baler. Material feeds into the Baler faster than you can react to release It. Also, NEVER attempt to clear debris or any­ thing else from the Baler while it Is running.

Failure to heed can result in death or serious Injury. ALWAYS exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8) BEFORE attempting to manually clear debris from the Baler!

When the twine can be seen moving into the Twine Tubes, stop Baler forward travel. Allow the twine to make at least one full wrap in this location and then move the Twine Tubes to the left side.

NOTE:

Normally, the bale can be adequately tied with two wraps of twine on the left side, several wraps across the center of the bale and two wraps on the right side. If the material being baled is slippery, it will help to place two wraps of twine on the center of the bale before moving to the left side in order to prevent the twine from sliding off the end of the bale.

Ejecting The Bale (Without Accessory Bale Bumper)

A WARNING Bales made with the Round Baler are LARGE, CYLINDRICAL and HEAVY! Serious personal injury or property damage could result if the Bales are NOT carefully and properly handledl NEVER eject or store Bales where they could possibly roll downhill!

The following procedure should be followed, in the sequence given, for ejecting a bale from a Baler that is NOT equipped with an accessory Bale Bumper:

1.

Back-up Baler a minimum of 15 feet. This provides for pull-ahead clearance, after the bale is ejected, so the Rear Door will close without hitting the bale.

2.

The PTO MUST be left engaged while ejecting the bale. However, if desired, the PTO may be operated at a slower speed.

NOTE:

Moving the Twine Tube all the way to the left engages and locks-open the Twine Cutoff Jaws.

A DAN GER BE SURE everyone is clear of the Rear Door BEFORE attempting to open or close It.

1 - Electric Actuator 2· Dual Twine Tubes Swung All the Way to the Right 3 • Cutoff Mechanism 4· Twine Box

3.

Activate the tractor hydraulics control lever and fully extend the Door Cylinders to open the Rear Door.

4.

After the bale is discharged, by the rotating Rollers, pull the Baler ahead, about 10 feet, to provide clearance between the Rear Door and the ejected bale.

S.

Activate the tractor hydraulics control lever and retract the Door Cylinders to close the Rear Door.

After the Door has closed, continue to activate the control lever, to build up pressure, until the Pressure Gauge reading is in the GREEN area or above.

Fig. 6-4 Next, gradually (in steps) move the Twine Arm (from left to right) to place wraps in several positions across the bale. When the Twine Arm reaches the right side, pause to allow two wraps of twine to be placed on the right side of the bale. Then, fully retract the Actuator to trip the Cutoff Jaws and cut the twine.

26

Ej ecting Th e Bale (With Accessory Bale Bumper)

A WA RNING Bales made with the Round Baler are LARGE, CYLINDRICAL and HEAVY! Serious personal Injury or property damage could result If the Bales are NOT carefully and properly handled!

NEVER eject or store Bales where they could possibly roll downhill!

The following procedure should be followed, in the sequence given, for ejecting a bale from a Baler that is equipped with the accessory Bale Bumper:

NOTE:

With the accessory B3.le Bumper installed, the Baler does NOT have to be moved, to provide for pUI/-ahead clearance after the bale is ejected. The Bumper causes the ejected bale to rol/ away from the Baler, about 10 feet on level ground, which is far enough to allow the Rear Door to close, without strik­ ing the ejected bale.

1.

The PTO MUST be left engaged while ejecting the bale. However, if desired, the PTO may be operated at a slower speed.

A DANG ER

DIFFICULT BALING CONDITIONS It is sometimes difficult to form bales when the crop is exceptionally short, slick and/or dry. Oats, straw and corn stalks are some examples. Use the following methods to help overcome difficult bale forming problems:

Material Preparation - Cut the material as long as possible. The longer the material, the easier it is for the bale to form and stay together after it is ejected.

- Prepare heavy, tight, even windrows. Fluffy, uneven windrows can cause feeding problems, requiring reduced ground speed until the bale is rolling.

- Rake several smaller windrows into a full Pickup­ width size windrow.

Operating Characteristics - Increase the ground speed, to maintain a constant flow of feed into the Baling Chamber.

- After the bale begins to rotate in the Bale Chamber, reduce PTO speed. This will reduce the bale tum­ bling action and therefore, cut down on material loss.

BE SURE everyone Is clear of the Rear Door BEFORE attempting to open or close It.

- Use more wraps of twine, than used in normal bale wrapping, but, do NOT wrap too close to the bale ends. Move the twine Guide Rod(s) in, toward the center hole(s), if the twine is slipping off the end(s) of the bale.

2.

THROAT GUIDE BAFFLE (Fig. 6-5)

Activate the tractor hydraulics control lever and fully extend the Door Cylinders to open the Rear Door.

3.

The bale is discharged, by the rotating Rollers, onto the Bale Bumper, which causes the bale to roll away from the Baler about 10 feet (3 meters) on level ground.

4.

After the bale has been ejected, activate the trac­ tor hydraulics control lever and retract the Door Cylinders, to close the Rear Door. After the Door has closed, continue to activate the control lever, to build up Rear Door pressure, until the Pressure Gauge reading is in the GREEN area or above.

For improved performance when baling dry short materials, like straw and grass hays, use the Throat Guide Baffle, supplied with the Baler. The Baffle is stored against the vertical channel in the center of the Baler right side.

When installed, the Baffle prevents crop material from falling back out of the Bale Chamber and onto the rear of the Pickup assembly. This helps to prevent plugging at the rear of the Pickup area. Adjust the Throat Guide Baffle for 1/16" clearance to the Roller outside diameter.

27

NOTE: ONL Y use the Throat Guide Baffle when baling very dry straw or short, dry and grassy hay. The Baffle prevents the bale from bulging out of the throat area and possibly plugging the area at the rear of the Pickup. The Throat Guide Baffle MUST be removed when baling normal materials, to prevent material build-up, which can cause driveline loading and pos­ sible fire.

BALE HANDLING & STORAGE

A WA RNI NG Bales made with the Round Baler are LARGE , CYLINDRICAL and HEAVY! Serious personal Injury or property damage could result If the Bales are NOT carefully and properly handled!

NEVER eject or store Bales where they could possibly roll downhill!

Because the bales made with the Baler are cylindrical and very heavy, special care MUST be exercised when ejecting and storing them, to keep them from starting to roll. When the bale is moved, make sure the original (flat) bottom of the bale remains at the bottom, to help prevent rolling.

When moving a bale to a storage area, observe the following recommendations, to minimize crop loss:

1.

Select a well-drained area, with complete ex­ posure to the sunlight, for storing the bale. Do NOT store the bale on plastic sheeting, or a similar material, because it will hold pockets of water.

2.

If possible, place the ends of the bale in a north

1 - Throat Guide Baffle In "Stored" Position

A WARNING ALWAYS use BOTH Rear Door Cylinder Locks when Installing, removing or checking the Throat Guide Baffle. Failure to heed, could result In death or serious Injury!

and south direction, so that the sun can dry-out the cylindrical surface of the bale, as it travels from east to west.

3.

Where space allows, set several bales in a row with their ends pushed tightly together, to form a long cylinder. Make sure that you do NOT form a water dam, by using to many bales in a row, without skipping a space. Also, make sure to maintain a clear path for the water to travel away from the bales.

4.

Maintain enough distance between rows so that one row does NOT overshadow the other and cut down its exposure to full sunlight.

A WARNING Improper Installation, adjustment or use of the Throat Guide Baffle may cause a fire which could result In machine damage and death or serious Injury.

Refer to the "Preparing for Field Operation" Chapter for procedures to properly install the Throat Guide Baffle.

28

OVERLOAD PROTECTION Rub ber Coupler The Drive Line is protected from high shock loads by a Rubber Coupler on the Output Shaft of the Gearbox.

The Coupler functions as a cushioning shock absorber.

In general, keep the PTO running at all times while baling. Since the Baler runs with NO pressure on the material until the bale becomes full-size, there is NO need to stop the Baler. Continuously running the PTO while baling, as opposed to stopping and starting, also helps to reduce parts wear and early failure.

NOTE: To avoid damaging the Baler Drive Line, slow tractor RPM to 1400 or less BEFORE engaging PTO. Then, engage PTO slowly. In addition, NEVER disengage the PTO quickly with a full bale in the Chamber. The mass of a rotating bale may cause a complete Drive Line reversal. When using a tractor equipped with a PTO brake mechanism, BE SURE to slow-down the engine speed BEFORE disengaging the PTO. Pickup Clutch (See Fig. 6-1) Overload protection to the Pickup Drive is provided by the ratchet-type Pickup Clutch. The Clutch is designed to slip when the Pickup becomes plugged.

29

CHAPTE R 7

ADJUSTM ENTS The Baler has been designed and factory adjusted to function properly under most field operating condi­ tions. However, due to the wide range of operating conditions encountered, some additional readjust­ ments may be required.

A CAUTION BEFORE proceeding to perform any adjust· ments on this unit, exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8).

PICKUP HEIGHT (Fig. 7-1) NOTE:

The Baler Pickup should ALWAYS be run as high above the ground as possible while still being able to pick up all of the crop.

A Pickup Lever mechanism is provided on the left side of the Baler for raising and lowering the Pickup to make operating height adjustments.

NOTE:

A small Chain is provided on the left side of the Baler to lock the Pickup Lever when it is in the fully raised "transport" position. BE SURE the Chain is slipped over the end of the Pickup Lever whenever the Baler is being transported to ensure that the Pickup will remain in the raised position.

1 - Lock Chain 2 - Pickup Height Adjustment Lever 3 - Pickup Lever Latch Rod

30

To raise or lower the Pickup, pull out on the Pickup Lever Latch Rod and then move the Pick up Lever over the hole in the Side Sheet, nearest to the desired posi­ tion. Release the Latch Rod while making sure the end of the Rod engages into the hole to lock the Pickup Lever at the desired setting. If the Baler is going to be transported, move the Pickup Lever to the top position and secure it with the Lock Chain.

PICKUP FLOTATIO N (Figs. 7-2 & 7-3) NOTE: Proper flotation is determined with the Pick­ up in the "Iowered" position and with the Ora wba r Hitch Plate adjusted so that the Twinebox is parallel with the ground.

The Baler is provided with a tension adjustable, float­ ing Pickup. For normal operating conditions on rela­ tively smooth ground , the recomm e nded Pickup Flotation Spring tension is approximately 30 pounds (14 kilograms) of lift required at th e cross pipe on the Hay Hold-down.

For extremely rocky or rough groun d conditions, in­ crease Pickup Flotation Spring ten sion to allow the Pickup to float easier. To increase Spring tension, proceed as follows:

NOTE:

Measure the length of the Springs, BEFORE making any adjustments, so that the Pickup can later be restored to the initial setting. Also, make sure to adjust BOTH Springs equally.

CHAPTER 8 LUBRICATION GENERAL INFORMATION

A CAUTION NEVER attempt to lubricate the Baler when any part of It Is In motion. ALWAYS, BE SURE to exercise the MANDATORY SAFETY SHUT· DOWN PROCEDURE (page 8) BEFORE proceeding to lubricate the Baler.

In addition to the Roller Chains, apply oil or foaming aerosol lubricant to the Telescoping PTO Drive Shields.

NOTE:

At the end of the harvesting season, coat all of the Roller Chains (and any other unpainted, exposed metal) with oil before placing the Baler into storage.

SEALED BEARINGS Sealed Bearings are lubricated for life and relubrica­ tion is NOT required, NOR should it be attempted.

GEARBOX

GREASING

NOTE:

General

On a routine basis after every 100 hours of operation, check the fluid level in the Baler Gearbox.

The level should be maintained, with a sufficient amount of SAE 90 Gear Lube, so that it just starts to run out of the Inspection Plug opening at the back of the Gearbox. Add fluid, as necessary, through the Gearbox Inspection Plug opening.

The Gearbox should be checked occasionally for oil drips and dust accumulation around the Seals which would indicate that the Seals are leaking. Oil which is tan in color and foams excessively indicates that it has water present in it. However, unless rust spots are visible inside the Gearbox, the fluid does NOT require replacement.

NOTE:

ON an annual basis, drain, flush out and refill the Gearbox with new SAE 90 Gear Lube. Do NOT overfill the Gearbox; only fill to the bottom of the Inspection Plug opening.

ROLLER CHAINS & PTO DRIVE SHIELDS Lubricate all Roller Chains every 6 to 8 hours of opera­ tion 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 better to lubricate Chains when they are warm (after use, rather than before).

NOTE: For Balers equipped with the accessory Automatic Chain Oiler, fill Oil Reservoir Tank as often as required with a lightweight oil (SAE 10 or equivalent). Usually, a full Tank should provide ade­ quate lubrication for producing 100 or more bales.

34

NOTE: Use an SAE mUlti-purpose, Lithium base grease for all locations.

Clean, inspect and repack the Wheel Bearings at least once a year.

Grease Fittings NOTE:

Grease all Fittings at the intervals of opera­ tion listed. Also grease all Fittings before and after storing the Baler and as otherwise listed.

Wipe dirt from the Fitting, before greasing it, to prevent any dirt from being forced into the Bearings or pivots. Replace any missing or defective fittings, when noted. To minimize dirt build-up, avoid excessive greasing.

CHAPTER 9 SE RVICE GENER AL INFO RMATION

A CAUTION BEFORE starting to do ANY Service routines on this unit, exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8).

The Bearing can be removed from the Shaft by loosen­ ing the Set Screw and then tapping on a punch, which is placed in the drift pin hole, to loosen the Collar.

Install Bearings with self-locking Collars in the fol­ lowing manner:

1.

Place the Bearing and Collar on the Shaft with the cam surfaces next to each other. Tighten the bolts on the Bearing Retainers.

2.

Mate the cam, of the Lock Collar, with the cam, of the Bearing inner ring.

3.

Press the Lock Collar against the Bearing's wide inner ring cam and turn it, in the direction of Shaft rotation, until it tightly engages. Tighten the Collar further, by tapping on a punch inserted in the drift pin hole.

NOTE:

The following information is also referredto in the Troubleshooting chapterofthis manual. It should be understood that all services, detailed in this chap­ ter, are Owner-Operator responsibilities. Where indi­ cated, certain service routines should only be carried-out by (or under the direction of) an authorized GEHL Dealer or GEHL Company representative.

Sealed Ball Beari ng Replacement (Fig. 9-1)

NOTE: To avoid damaging the Lock Collar, do NOT overtighten it.

Sealed Ball Bearings are used on ·various Shafts on the Baler. This type of Bearing is generally retained with a Self-locking Eccentric Collar. The Lock Collar has a counterbored recess, which is eccentric with the Collar bore. This eccentric recess engages or mates with an eccentric end of the Bearing inner ring, when the Bear­ ing is assembled on the Shaft. The Bearing is engaged, on the inner ring cam, by the Collar. This assembly grips the Shaft tightly with a positive binding action that increases with use. The Collar Set Screw provides supplementary locking.

4.

Tighten the Set Screw in the Lock Collar.

Gib Key The Gib Key, a tapered key with a tang on the thick end, is a combination locking device and hub retainer.

The Gib Key will lock the hub in place and retain it from turning. The hub MUST have a matching tapered keyway for use with the Gib Key.

Removal (Fig. 9-2) 1.

Remove paint from the Shaft on both sides of the hub.

2.

Loosen the Set Screws.

3.

Drive hub away from Key head, using a large punch or drift. Make sure that Gib Key does NOT move with hub.

4.

- Pickup Drive Chain, #60 of 79 Links with (1) Spring Clip-type Connecting Link (Slip-fit) and (1) Offset Link.

7-1/2" to 7-3/4" (maximum), for a #80 Chain, it should be 10" to 10-5/16" (maximum) and for a #100HK Chain, it should be 12-1/2" to 12-7/8" (maximum). If the distance measured is greater than the "maximum", replace the Chain.

NOTE:

Replace the Drive Chain when the Chain Tensioner for that particular Chain only has 112" (13 mm) of adjustment remaining. Do NOT shorten the Chain by removing a Link (or Links).

Chain Removal & Installation All six Drive Chains on the Baler are provided with Spring Clip-type Connecting Links to aid in Chain removal and installation.

NOTE: BEFORE attempting to remove the Spring Clip-type Connecting Link from a Drive Chain, to remove the Chain for service, release the tension on the Chain by loosening its Chain Tensioner. Also, BE SURE to adjust the Chain for proper tension, after installing a cleaned and re-oiled (or a new) Chain.

The Gearbox can be removed from the Baler for taking it to a GEHL Dealer for internal component service.

NOTE: Internal Gearbox component repairs and/or replacements should only be attempted by (or under the direction of) an authorized GEHL equipment dealer.

Sprocket wear is most often caused by an excessively worn Drive Chain. Factors such as operating condi­ tions (dirt and temperature), amount of power trans­ mitted, operating speed of the chain and lubrication (or lack of it) influence the life of the Chain.

To effectively lubricate the Chain joints, lubricant should be delivered to the spaces between the side bars.

It is also essential, that an adequate lubricant film be retained between the rollers, bushings and pins to maintain a flexible Chain. If a Chain becomes stiff, remove it and soak it in a solvent to loosen dirt and corrosion from the joints. Then, wash the Chain in clean solvent and soak it overnight in oil so the oil can penetrate between all joints.

A Chain which has worn 3% (1.03 times its original length), should be removed and replaced. To determine the amount of wear on a particular Chain, an easy check is to measure 10 Links of the Chain in a straight line, from the center of one pin to the center of the 10th following pin. For a #60 Chain, the distance should be

Removing Gearbox To remove the Gearbox from the Baler, proceed as follows:

1.

Release the Chain tension and then uncouple the Main Drive Chain. Refer to the Drive Chains topic in the Adjustments chapter and in this chap­ ter, for detailed instructions on Drive Chain removal.

2.

Remove the PTO from the Gearbox Shield.

3.

Loosen the 4" Clamp on the Jackshaft Shield.

4.

Remove the hardware securing the Twine Tie Guard to the Gearbox Shield. Then, remove (4) 5/16-18 x 3/4" Flanged Head Locking Cap Screws and the Gearbox Shield.

5.

Remove the (3) 5/8 x 2-1/2" Cap Screws and Lock Nuts securing the Splined Coupler (Gearbox side of the Rubber Coupler Assembly) to the Rubber Coupler Ring.

NOTE: Do NOT lose any of the Shims when remov­ ing the Gearbox mounting Bolts in step 6. The Shims are used to obtain proper alignment between the Gear­ box Output Shaft and Jackshaft. Refer to the Jackshaft Alignment topic later in this chapter for more details.

6.

Coupler not only provides a means of connecting the Gearbox Output Shaft to the Jack shaft, but it also provides cushioning from high shock loads due to en­ gaging and disengaging the PTO.

NOTE: The Jackshaft and Gearbox Output Shaft MUSTbe maintained in proper alignment at ALL times.

Anytime the Jackshaft or Gearbox has been removed, proper alignment MUSTbe re-established during reas­ sembly.

Jackshaft Alignment (Fig. 9-7) When installing the J ackshaft, maintain a distance of 4-1/8" (lOS mm) between the end of the Jackshaft and the Bearing Support Plate as shown in the illustration.

Check for parallel alignment (within 1/32" vertically and horizontally) between the Jackshaft and the Gear­ box Output Shaft (it may be necessary to Shim and/or to twist the Gearbox, in order to obtain parallel align­ ment). Once aligned and BEFORE tightening the (6) Coupler bolts, measure the total runout of the Jack­ shaft.

NOTE:

When measuring for total runout, the Main Drive Chain MUST be disconnected and the Gearbox Input Shaft MUST be rotated by hand in order to obtain accurate results.

Remove the (4) Grade 8 Cap Screws and Lock Washers located at the bottom of the Gearbox and then remove the Gearbox, all Shims and the (4) 3/8" thick Spacer Bars. Remove the Splined Coupler from the Gearbox Output Shaft (Coupler has a sliding fit on Shaft).

Installing Gearbox 7.

To install the Gearbox, reverse the steps for "Removing Gearbox" and take into account the following noted information.

NOTE: Refer to the "Main Drive Jackshaft & Rub­ ber Coupler" topic, next in this chapter, to obtain proper alignment between the Gearbox Output Shaft and the Main Drive Jackshaft. Also, BE SURE to properly adjust the Main Drive Chain tension following the details in the Adjustments chapter.

8.

Fill Gearbox to the proper level with SAE 90 Gear Lube. Refer to the Lubrication chapter for additional details.

NOTE: Often, the runout can be reduced by loosen­ ing (3) of the Coupler Bolts 1/2 turn and then tapping on the Jackshaft in the proper direction. BE SURE to retighten the (3) Coupler Bolts, after the Jackshaft is within the 0.027" (maximum) runout limit.

PICKUP ASSEMBLY The Pickup should be inspected on a routine basis every 100 hours of operation. The following areas should be inspected:

Pickup Clutch (See Fig. 9-5) Included in the ratchet-type Pickup Clutch are (16) spring-loaded Cams which provide a preset torque out­ put of approximately 442 ft-Ib (600 Nm). The Clutch is NOT adjustable. If the Clutch does slip while baling (because of a Pickup overload), reduce the PTO speed (and therefore the Pickup Drive Speed) and usually, the Baler will unplug itself and the Clutch will stop slipping.

NOTE: If the Clutch continues to slip or if it be­ comes jammed, it is recommended that the Baler be taken to an authorized GEHL dealer for removal, repair and/or replacement.

Pickup Tines (Fig. 9-8) Check for broken or bent Tines. Straighten bent Tines, if possible. Replace a broken Tine as follows:

1.

Loosen the (4) 5/16 x 3/4 Cap Screws securing the Stripper(s) nearest to the broken Tine and remove the Stripper(s).

2.

Remove and retain the 5/16 x 2 Flange Head Cap Screw and Lock Nut securing the Tine Holder to the Tine Bar.

A WARNING Inflating or servicing tires can be dangerous.

Whenever possible, trained personnel should be called to service and/or mount tires. In addition, do NOT place fingers on tire bead during Inflation; serious injury or amputation could result! In any event, to avoid possible fatal or serious Injury, follow the safety precautions below: • BE SURE the Rim Is clean and free of rust.

Lubricate both the tire beads and rim flan­ ges with a soap solution. Do NOT use 011 or grease.

• Use a Clip-on tire chuck with a remote hose and gauge which allows you to stand clear of the tire while inflating It. • 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, re-Iubricate both p~uts and re­ Inflate It. Inflation pressure bey\ond 35 PSI with unseated beads may break the bead or rim with explosive force sufficient to cause fatal or serious injury.

• After seating the beads, adjust the Infla­ tion pressure to the recommended operat­ Ing pressure listed.

• Do NOT weld, braze, or otherwise attempt to repair and use a damaged rim.

HYDRAULIC CONNECTIONS NOTE: The tractor MUST have a remote hydraulic output capable of operating the Rear Door, double-ac­ ting, HydrauliC Cylinders. If the Baler is equipped with an optional HydrauliC Twine Wrapping System, the tractor MUST have an additional remote hydraulic output, to operate the Twine Wrapping, double-acting, Hydraulic Cylinder.

Install the appropriate quick-disconnect fittings, to match your tractor connections, onto the Baler Hydraulic Hoses . The quick-disconnect fittings are to be purchased local~; they are NOT provided with the Baler. Use Loctite ,or equivalent pipe sealing com­ pound, on the fitting threads.

Connect the Hoses to the proper tractor hydraulic out­ lets, start the tractor and operate the remote control valve(s), to extend and retract the Cylinder(s) several times, to purge the air out of the system.

NOTE:

To help feed twine through the Twine Tubes, position them so they are in a vertical position.

AI/ow about 12-18" of twine to extend from the Tubes before starting to bale. After the first bale has been tied and the twine cut, the twine (extending from the Tubes) will be held by the Clamp Jaws. The Jaws should provide an 18" tail of twine for starting to wrap the next bale.

Third & Fourth Twine Ball Routing Pull the end of the twine from the center of the third ball, through the Rear and Center Guides on the Twinebox Cover, through the Upper Guide in the Twinebox side and out to the Twine Tensioner, if used.

From there, route the twine the same as for the first ball, except route the twine through the other Twine Tube.

TWI NE ROUTING (Figs. 10-5 & 10-6) To thread the Baler with twine, proceed as follows: Place up to four balls of twine in the Twinebox and tie the ends, if desired, for continuous feeding.

NOTE: ALWAYS tie the outside twine end of the first bal/ to the inside twine end of the next bal/, when placing twine bal/s in the Twinebox for continuous feeding.

First & Second Twine Ball Routing Pull the end of the twine from the center of the first ball through the Front Guide on the Twinebox Cover, through the Lower Guide in the Twinebox Side and out to the Twine Tensioner, if used. From there, route the twine through the bushing in the side of the Twine Tie Guard and over to the Glass Guide on top of the Twine Tubes.

THROAT GUIDE BAFFLE (Fig. 10-9) For improved performance when baling dry, short materials, like straws and grass hays, install the Throat Guide Baffle, supplied with the RB 1710 Baler. The Baffle is stored on the right side of the Baler behind the Pressure Gauge.

1 - Twine Guides

Fig. 10-5

When installed, the Baffle prevents bale material from falling back out of the Bale Chamber, onto the rear of the Pickup Assembly. This will help prevent plugging at the rear of the Pickup area.

Adjust the Throat Guide Baffle for 1/16 inch clearance to the Roller outside diameter, as shown.

46

A CAUTION ONLY use the Throat Guide Baffle when baling very dry straw or short, dry grass hays. The Throat Guide Baffle MUST be removed when baling damp to normally moist materials to prevent material build-up which can cause drive line loading and possible fire. Also, BE SURE to use BOTH Rear Door Cylinder Locks when Installing, removing or checking the Baffle. Improper Installation, adjustment or lise of the Throat Guide Baffle may cause a fire! Failure to heed, can result In personal Injury or machine damage.

To install the Throat Guide Baffle, proceed as follows: 1.

Raise the Rear Door and engage BOTH Cylinder Locks. BE SURE that the Door is properly sup­ ported and that BOTH Cylinder Locks are in engaged.

2.

Position the Baffle so that there is 1/16" clearance between the edge of the Baffle Angle and the weld seam on the outside diameter of the 20th Roller (the 20th Roller is located just above the Baling Chamber Throat).

3.

Once the proper positioning is obtained, secure the Baffle with the (4) 3/8 x 3/4 Tapping Screws provided. Holes are provided in the Baling Cham­ ber Side Sheets for mounting the Throat Guide Baffle.

4.

Test run the Baler, very slowly, to check for any rubbing. Repeat Steps 1 thru 3, above, if there is any indication of rubbing.

5.

Raise the Rear Door, disengage the Cylinder Locks and lower the Rear Door.

DUAL-POSITION WHEEL AXLES (Fig. 10-8) The RB1710 Baler is provided with dual-position Wheel Axles for making tread width adjustments.

When the Baler is equipped with standard size tires (IlL x 14, 6-ply Implement Tires), the Axles should be installed with the 3/4-10 x 6-1/2" Bolts going through the inner mounting holes in the Axle Shafts.

When the Baler is equipped with wide, flotation tires (31 x 13.5 xIS, 6-ply Implement Tires) or when a wider tread width is desired (for hillside baling, as an example), the Axles may be installed with the 3/4-10 x 6-1/2" Bolts going through the outer mounting holes in the Axle Shafts.
