Rear Single Drive Wheel Tread Settings—Steel Wheels

IMPORTANT: Tractors equipped with tires narrower than 520 and have a starter 72 kg (159 lb.) and two 205 kg (452 lb.) inner wheel weights must not set rear treads narrower than 1676 mm (66 in.). Doing so will result in damage to tractor.

NOTE: Refer to charts for rear tires shown earlier in this section to determine rim position for 16-position wheels.

IMPORTANT: Refer to “Minimum Tread Setting With Air Trailer Brakes And Inner Wheel Weights” section for further restrictions on tractors equipped with optional air trailer brakes.
