Avoid personal injury or death. Remove MFWD drive shaft if towing tractor with front wheels on a carrier. Loss of electrical power or transmission-hydraulic system pressure engages the MFWD and pull tractor off the carrier, even with switch in the DISENGAGED position.

IMPORTANT: Avoid transmission and drivetrain component damage:

  • NEVER attempt to start tractor while towing.
  • If possible, operate engine above 1250 rpm to provide lubrication, power steering and power brakes. Have an operator steer and brake tractor.
  • Do not tow a tractor faster than 8 km/h (5 mph). Do not exceed 3 km/h (2 mph) for the first ten minutes in below freezing temperatures.
  • Check transmission-hydraulic oil level. Add 1 L (1 qt) for each 90 mm (3-1/2 in) Front wheels are raised off the ground. DO NOT raise wheels more than 305 mm (12 in). Drain excess oil after transporting.

  1. If equipped with MFWD, remove drive shaft if towing tractor with front wheels on a carrier:

    1. Remove three cap screws (A) and slide drive shaft shield (B) away from drop housing. Repeat on opposite end.

    2. Remove spring pin (C) using a punch and hammer.

    3. Support drive shaft and slide coupler (D) toward drop housing.

    4. Remove drive shaft, shields and couplers.
