OPERATION DPF REGENERATION DPF (Diesel particulate filter) is equipped for collecting PM (paticulate matter) contained in exhaust gas.

When the engine electronic control unit (ECU) detects a specified amount of PM, "DPF regeneration" is required.

NOTE: DPF regeneration has two types which are "Automatic regeneration" and "Manual regeneration". If "Automatic regeneration" isn't conducted and soot amount increases (over 100%), "Manual regeneration" will be required. <Soot amount from 80 to 100%: Automatic regeneration> Normally, DPF regeneration works automatically.

When soot amount exceeds 80%, DPF regeneration starts automatically. During regeneration, exhaust gas becomes hot. Then "Exhaust gas high-temperature lamp" turns on, and regeneration takes about 20 to 30 minutes to finish.

NOTE: If Automatic regeneration isn't conducted and soot amount becomes from 100 % to 140%, Manual regeneration will be required. Automatic regeneration will not be conducted.

Stop operating immediately and conduct Manual regeneration. <Soot amount from 100 to 120%: Manual regeneration 1st stage> When soot amount exceeds 100% under special condition, "Regeneration Request Lamp" blinks and buzzer sounds. Then you have to start DPF regeneration manually. Apply the parking brake, set the throttle to idle and push the DPF regeneration switch.

43

TG6407, 6507, 6557, 6687 <Soot amount from 120 to 140%: Manual regeneration 2nd stage> If you didn't activate DPF regeneration at 1st stage and soot amount exceeded 120%, the engine rotation speed will be restricted to 1 500 rpm, and the output decreased to 50%. At this point immediate DPF regeneration is required. You must stop operating and conduct Manual regeneraion. Apply parking brake, set the throttle to idle and push the DPF regeneration switch. <Soot amount from 140 to 160%: Service tool regeneration> When soot amount exceeds 140%, this means "Overload 1st stage". If you continue operating for 2 hours, engine rotation speed will be restricted to 1 200 rpm.

You have to contact your dealer and regeneration must be conducted by using a service tool. <Soot amount over 160%: DPF replacement> When soot amount exceeds 160%, this means "Overload 2nd stage". If you continue operating for 1 hour, Engine rotation speed will be restricted to 1 200 rpm.

You have to contact your dealer and the DPF must be replaced.

WARNING: Do not leave the machine during DPF regeneration.

During DPF regeneration, exhaust gas will be hot. Therefore, make sure that there is nobody/no combustible material around tail pipe during "DPF regeneration".

During DPF regeneration, exhaust pipe will become hot. Therefore, be careful not to touch it.

TG6407, 6507, 6557, 6687 BREAK-IN PERIOD

STARTING

Operation of tractor within the first 50 hours can be a major factor in determining the performance and life of the engine and tractor:

Pre-Start Inspection Prior to daily operation of tractor, a few basic procedures should be followed to ensure tractor is in operating order to insure life and dependability:

• The engine may be operated at full speed but excessive load should be avoided. If engine begins to “lug”, operate in a lower gear to maintain higher engine speed.

• Make sure all safety shields are in place and secured properly.

• Make sure operator is instructed on correct and safe operation of tractor and related attachments or implements.

• Check coolant level and check engine, transmission and other oil levels frequently during break-in period. Watch for evidence of leakage of above fluids.

Replenish levels as required and repair any leaks that may have formed.

• Check coolant, engine oil and transmission oil levels and replenish as necessary.

• Check fan belt tension and adjust as required.

• Tighten any nuts, bolts, or screws that may have loosened and tighten as necessary. This is especially true of wheel retaining bolts. All fasteners on this tractor are metric.

• Make sure radiator, air intake screens and radiator screen are clear of debris to provide maximum engine cooling efficiency.

• Check operation of clutch, brake and throttle controls. All controls must be operated freely and adjusted correctly.

• Be observant of clutch and brake pedal free-play and readjust as required. Lining materials used on clutch and brake discs “bed in” in the first few hours of operation and may need early and frequent readjustment.

• Conduct a general inspection of tires, tire pressure and wheel bolt torque. Observe for external signs of leakage and correct before operating tractor. Check steering for excessive looseness.

• Keep clean around fuel filler area and use correct grade fuel free from contamination.

• Check for adequate fuel supply. It is recommended fuel tank be filled following each day’s use to reduce condensation and provide full tank for next use.

• Initial oil and oil filter maintenance are required after first 50 hours use for engine. Subsequent change interval is every 200 hours for engine oil and every 400 hours for engine oil filter.

• Check operation of lights and warning flashers. If tractor is to be transported on public road, ensure slow-moving vehicle emblem is in place.

CAUTION: Proper maintenance practices cannot be over-emphasized. They are required for safe operation. Refer the page of “Lubrication and Maintenance” section for full details.

NOTE: Requirements may be varied on locally for used of warning flashers and slow moving vehicle emblem. Check local safety codes.

WARNING: Carefully read and understand the SAFETY section of this manual. Your life, and that of others, can be in danger during the starting of the tractor.

Always start and operate the engine in a well ventilated area.

If in an enclosed area, vent the exhaust to the outside.

DO NOT modify or tamper with the exhaust system.

TG6407, 6507, 6557, 6687 Restarting Warm Engine

• Test all controls (steering, braking, etc.) before operation.

When restarting an engine that is still warm from previous use, the same procedure is applied as with “Normal Starting” except step No. 9 may be omitted.

Use of glow plugs is not necessary when starting a warm engine.

NOTE: Installation of optional engine block heater is recommended in cold weather conditions.

Consult your dealer.

IMPORTANT: Never use any kind of starting fluid to start engine equipped with glow plugs.

Otherwise, such starting fluid will contact hot glow plug and it will result severe engine damage.

Cold Weather Starting Procedure for starting an engine in colder ambient temperatures is identical to “Normal Starting” procedure except for the following:

• Use of proper fuel for ambient temperature is recommended.

• At temperatures below 4 °C (39 °F) use of No. 1 (No. 1-D) diesel fuel is recommended due to possible “fuel gelling” characteristics of No. 2 (No. 2-D) fuel at cold ambient temperature.

• The central hydraulic reservoir, which provides supply of hydraulic fluid in addition to transmission and center housing lubrication, will require additional warm-up time due to colder (thicker) oil. Refer to “Warm-Up Period” at right.

In any case that a booster battery is required to start engine, ensure a booster battery is connected in parallel with the original battery. When using a booster battery and booster cables, always connect the both positive (+) terminals first. Then install booster cable on the booster battery negative (-) terminal. And connect it to ground of the tractor or negative (-) terminal of the original battery. Finally make sure the booster cable ends are away from tractor body or other battery to prevent short circuit or any sparks.

Warm Up Period After starting a cold engine, let engine idle at slow speed to make sure all engine components are lubricated.

In colder ambient temperatures, extended warm-up time will be required to also warm hydraulic fluid and lubricate driveline components.

TABLE 1: Suggested warm-up period Ambient Temp. ˚C °F 0 & up 32 & up 0 to -10 32 to 14 -10 to -20 14 to -4 -20 & less -4 & less

Warm-Up Time Time 5 to 10 min 10 to 20 min 20 to 30 min 30 min or more

IMPORTANT: Improper warm-up can result in severe engine damage, hydraulic pump seizure, driveline bearing / gear damage and / or sluggish steering / braking CAUTION: Make sure parking brake is securely applied and all controls are in neutral while warming up the tractor. Do not leave unit unattended.

OPERATION Operator Observations

Starting Circuit For The Engine

Constant attention should be paid to the following points during operation:

Tractor is equipped with a safety starting system to protect the operator. To permit tractor to be started (start motor to operate), ALL the following is required:

• Engine oil pressure lamp will come on in case of low engine speed. Stop engine immediately.

• Operator seated on the seat.

• Battery charge lamp will come on if battery is not being charged properly. Stop engine and investigate the cause.

• PTO switch in OFF position

• In case of overheated engine, the coolant temperature gauge reaches “H“ indication. Stop engine, allow to cool down and investigate cause.

• Forward / reverse lever in Neutral

• Range shift lever in Neutral (HST type)

• Depressing clutch pedal (Standard & Dual clutch type)

• Do not run out of fuel. Before fuel gauge reaches the indication of “E” (empty), refill diesel fuel otherwise, it may result with need to bleed air from fuel circuit.

CAUTION: DO NOT attempt to service tractor with engine running or hot. Allow to cool.

WARNING: Safety starting system is installed for your protection. DO NOT bypass or modify the safety starting system.

If the neutral start switch system does not operate properly as explained above, contact your dealer immediately and have the system repaired.

NOTE: Refer to “Troubleshooting” when defect is indicated, to assist locating problem.

Periodically check that the starting circuit is working correctly. The procedure for check is as follows: 1. Check that there are no bystanders around the tractor in order to avoid the inadvertently start.

2. Depress clutch pedal (Standard & Dual clutch type) and brake pedals. Attempt to start the tractor with the gear shift levers and PTO switch OFF. The tractor should start.

3. Depress the clutch pedal (Standard & Dual clutch type) and brake pedals. Attempt to start the tractor with the gears engaged and the PTO switch ON. The tractor should NOT start.

4. Depress the clutch pedal (Standard & Dual clutch type) and brake pedals. Attempt to start the tractor with the gears in neutral and the PTO switch ON. The tractor should NOT start.

If starting system is not working correctly it must be repaired immediately by your dealer.

The starter motor will rotate when not sitting in the seat, but the engine will not start.

The engine will automatically stop about 3 seconds after the operator leaves the seat. Do not leave the seat while operating the tractor.

TG6407, 6507, 6557, 6687 CLUTCH FREE-PLAY ADJUSTMENT FIG. 6-47: Check clutch pedal free-play regularly and adjust as necessary. Correct clutch pedal free-play, A, is 25 to 35 mm (1 to 1 - 3 / 8”) when measured at the end of the pedal as shown.

NOTE: Through use, clutch free-play will be reduced.

A

IMPORTANT: Correct free-play must be maintained to; reduce wear on clutch and release bearing, and allow complete disengagement when pedal is depressed.

FIG. 6-47

FIG. 6-48: To adjust clutch pedal free-play, loosen lock nut (1) (right-hand thread), and lock nut (2) (left-hand thread). Adjust turnbuckle (3) on linkage until free-play is correct. Lengthening linkage will increase free-play, shortening linkage will reduce free-play.

２ ３

Secure by retightening lock nuts.

1

FIG. 6-48 BRAKE ADJUSTMENT FIG. 6-49: Unlatch pedals and check free-play of each brake pedal. Correct free-play, A, of each individual brake pedal is 30 to 35 mm (1 - 1 / 8 to 1 - 3 / 8”).

A

NOTE: Through use, free-play will increase and brake balance will be affected. Adjust and balance brakes before free-play is excessive.

FIG. 6-50: Loosen lock nut (1) (right-hand thread), and lock nut (2) (left-hand thread). Adjust turnbuckle (3) so free-play is correct for respective brake pedal.

Repeat procedure for other brake so free-play in pedals is equal. Secure lock nuts against turnbuckles.

FIG. 6-49

When adjustment is complete, latch pedals together and operate tractor at low speed. Depress pedals. If tractor has tendency to “pull” to 1 side, slight readjustment of 1 brake is required.

2

2 3

3

Make sure lock nuts are secured when brake adjustment is complete. Check operation of parking brakes after adjustment is made.

１

CAUTION: Brakes must be adjusted evenly to permit equal braking action at both rear wheels when brake pedals are latched together.

FIG. 6-50 134

LUBRICATION & PERIODIC MAINTENANCE WHEELS & TIRES Check wheels and tires periodically for correct inflation pressures, tight wheel bolts, and any physical damage that may be a detriment to tractor operation and operator safety. Correct condition prior to tractor operation.

TABLE 22: Tire inflation pressure

Model

Tire Inflation Pressures Maintaining correct tire pressure will help insure tire long life. If tires have deep scratches, cuts or punctures, the respective tire should be repaired or replaced by qualified personnel as soon as possible.

IMPORTANT: If necessary to replace any tire(s), ensure original tire size is used. This is particularly true on 4WD models to ensure correct amount of front axle overspeed (or “lead”) is maintained.
