Parking Brake Adjustment
WARNING: Never attempt to adjust the brakes while the engine is running. Always disengage PTO, stop engine and remove key to prevent unintended starting.
If the tractor does not come to a complete stop when the brake pedal is completely depressed, or if the tractor’s rear wheels can roll with the parking brake applied, the brake is in need of adjustment. The brake disc can be found on the right side of the transmission in the rear of the tractor. Adjust if necessary as follows:
NOTE: Have a replacement cotter pin on hand before beginning this adjustment.
•Looking at the transmission from the right side of the tractor, locate the brake puck and brake disc. See Figure 11.

•Remove and discard the cotter pin which secures the crown nut to the assembly. See Figure 11.
•Loosen, but do NOT remove, the crown nut found on the right side of the brake assembly.
•Insert a feeler gauge (set at .011”) between the brake disc and the brake puck.
NOTE: If a feeler gauge is unavailable, a typical business card is approximately .011” thick.
•Retighten the crown nut loosened earlier, leaving a
.011” gap between the brake disc and the brake puck.
•Insert a new cotter pin to secure the crown nut in place. Do NOT reuse the old cotter pin.
Steering Adjustment
If the tractor turns tighter in one direction than the other, or if the ball joints are being replaced due to damage or wear, the steering drag links may need to be adjusted.
Adjust the drag links so that equal lengths are threaded into the ball joint on the left side and the ball joint on the right side:
•Loosen the jam nut found on the drag link at the rear of the ball joint. See Figure 12.

•Remove the hex nut on the top of ball joint. See Figure 12.
•Thread the ball joint toward the jam nut to shorten the drag link. Thread the ball joint away from the jam nut to lengthen the drag link.
•Replace hex nut and lock washer and retighten the jam nut after proper adjustment is achieved.
NOTE: Threading the ball joints too far onto the drag links will cause the front tires to
Front tire
•Place the steering wheel in position for straight ahead travel.
•In front of the axle, measure the distance horizontally from the inside of the left rim to the inside of the right rim. Note the distance.
•Behind the axle, measure the distance horizontally from the inside of the left rim to the inside of the right rim. Note the distance.
•The measurement taken in front of the axle should be between 1/16" and 5/16" less than the measurement taken behind the axle.
•Adjust if necessary.
