The foot throttle may also be used to temporarily increase the engine speed above the hand throttle setting. Low Range Neutral D.
Use these control levers to control the working depth and pull of implements attached to the three point hitch as follows: Differential Lock Pedal Located at the rear of the right floor board, the differential lock is used to gain additional traction when operating the tractor on wet or loose soil. When the pedal is depressed the rear wheels of the tractor are prevented from rotating independently of one another. See Figure 16.
Seat Adjustment Lever Mid PTO Lever The seat adjustment lever is located beneath the left side of the seat. This lever is used to adjust the seat forward or backward to the desired operating position. See Figure 19. The tractor’s Mid PTO is used power implements designed to be operated at 2000 RPM. The mid PTO lever is located in the panel below the right side of the seat. See Figure 21. • Turn the PTO switch to the manual position. • Pull the lever upward to engage the Mid PTO.
SECTION 2: OPERATION ROLLOVER PROTECTIVE STRUCTURE (ROPS) FUELING THE TRACTOR This tractor is equipped with a foldable Rollover Protection Structure (ROPS) and seat belts. When used together they are effective in reducing injuries to the operator in the event of an accidental tractor rollover. The safety provided by the ROPS is minimized if the seat belt is not properly adjusted AND buckled. WARNING: Always wear the seat belt when operating the tractor equipped with a ROPS.
• Tighten the fuel cap securely, and immediately wipe up any spilled fuel. • To minimize condensation, keep the fuel tank as full as possible without filling to capacity. It is a good practice to fill the fuel tank at the end of the day to reduce overnight condensation. • STARTING THE ENGINE WARNING: Always sit in the operator’s seat when starting the tractor, Never attempt to start the engine while standing beside the tractor. WARNING: Never use a starting fluid, such as ether, as a starting aid.
• STOPPING THE ENGINE Set the throttle lever in approximately the middle position (40hp). See Figure 25. • Throttle Lever to Mid Position • • • • On/Preheat Position PTO Switch In Neutral • Figure 25 • • Turn the ignition switch to the "ON/Preheat" position. Refer to Figure 25. NOTE: Some of the instrument panel lamps will light momentarily to indicate they are functioning. The oil pressure and battery charge lamps should remain on until the tractor is started.
• Fully depress the clutch pedal and proceed as follows: - Shift the Forward/Reverse Shift Lever to desired direction. See Figure 27. Depress Clutch Pedal Throttle Up Using Hand or Foot Throttle Disengage Parking Brake Forward Figure 29 Reverse • NOTE: If operating power driven equipment running off the PTO, the throttle must be increased to the 540 PTO mark unless otherwise specified in the equipment operator’s manual. Use the gear shift levers to select a safe travel speed.
• If leaving the tractor, turn the ignition key to the OFF position and remove the key. • If parking on an incline, chock the wheels to prevent accidental rolling of the tractor. • Prior to going downhill, reduce the engine speed and shift the transmission into a lower gear to take advantage of the braking action of the engine.
CHECK WHILE OPERATING Fuel Gauge While operating the tractor, regularly check the gauges and warning lights on the instrument panel to ensure the tractor is functioning properly. Regularly check the fuel gauge. Do not allow the fuel tank to empty completely. If the tractor runs out of fuel, air is allowed to enter the fuel system, which could cause the engine to run poorly after refueling.
USING THE DIFFERENTIAL LOCK USING THE FRONT WHEEL DRIVE Depressing the differential lock pedal engages a mechanism in the transmission that locks the differential. This prevents the rear wheels from rotating independently of each other and provides constant power to both rear wheels when additional traction is needed. Use the front wheel drive when the conditions require the additional traction provided by all four wheels driving the tractor.
Penetration w/Draft Control and Position Control Ground Surface Engage Disengage soft soil hard soil MID PTO LEVER Penetration w/Draft Control Only Figure 32 • Figure 34 After determining a desired working position using one, or both, controls, the stop bolts can be used to ensure the levers are returned to their selected positions. Loosen the wing screws and slide the stop(s) against one (or both levers) and re-tighten the wing screws.
• USING THE THREE POINT HITCH WARNING: Always disengage the PTO, stop the engine, and set the parking brake before dismounting the tractor to connect, disconnect, or adjust three point hitch mounted implements. Never stand between the rear wheels and the implement when attaching and adjusting the implement. Following the information provided in the implement owner’s manual, attach the left lift rod to the lower link using one of the three holes provided in the lift rod.
TRACTOR WEIGHTING USING REMOTE HYDRAULICS The tractor is equipped with a remote hydraulic system for powering hydraulically driven implements that are approved for usage on the tractor. When implements are installed on either the front or rear of a tractor, the tractor’s normal balance is altered. • As a rear mounted implement is raised to the transport position, the balance point of the tractor shifts rearward, which may result in a loss of steering control and tractor stability.
SECTION 3: ADJUSTMENTS ADJUSTING THE SEAT A For the comfort of the operator, a single lever adjustable seat is provided to set the fore to aft position of the seat. Adjust the seat to the most comfortable position that allows you to operate all controls and pedals. WARNING: Do not adjust the seat when the tractor is moving, as this could cause the operator to lose momentary control of the tractor and result in an accident.
• • Tighten the adjusting bolt as necessary to remove the play from the front axle, then retighten the jam nut. Clutch Rod Lower the front of the tractor to the ground. Turn Clevis to Adjust ADJUSTING THE FAN BELT TENSION Clevis Pin 0.79 -1.18 in. Free Play If the fan belt becomes loose, the engine may overheat and/or the battery may not charge. Check the belt tension and, if necessary, adjust as follows: • With approximately 22 lbs.
ADJUSTING THE MICRO SWITCH HEIGHT ADJUSTING REAR WHEEL TREAD WIDTH The PTO micro switch, located inside the right fender adjacent the position control lever, is initially set so that the PTO will disengage when the 3-point hitch lower links are raised to prescribed height. When operating the tractor in the field, it is sometimes necessary to change the rear wheel tread width to a narrower position to avoid plant rows, or to widen the tread to improve stability when operating on slopes.
• Raise and support the rear of the tractor. • Torque the nuts to 145-165 ft. lbs. (196-226 N•m). • Adjust the tread widths as shown by changing the mounting relationship of the wheel disc to the rim mounting brackets and/or the relationship of the dish of the wheel disc to the axle. See Figure 49. • Raise the rear of the tractor, remove the supports, and lower the tractor to the ground. Rim Mtg. Bracket Rear Axle Wheel Disc Rim Mtg. Bracket 45.
SECTION 4: MAINTENANCE The service life and reliability of any machine depends upon the care it is given. Proper lubrication and maintenance is a vital part of that care. Using the Lubrication and Maintenance Chart as a guide, monitor the hourmeter on the instrument panel to ensure the required maintenance procedures are performed. The maintenance schedule reflects the minimal requirements to maintain the equipment. More frequent inspections and maintenance is preferable.
