Troy-Bilt Brake Adjustment and Lawn Mower Seat Guide

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:

•Looking at the transmission from the right side of the tractor, locate the compression spring and brake disc. See Figure 15.

•Loosen, but do NOT remove, the hex nut found on the right side of the brake assembly. See Figure 15.

•Using a feeler gauge, set the gap between the brake disc and the brake puck at .011".

•Re-tighten the hex nut loosened earlier.

Seat Adjustment

WARNING: Before operating this machine, make sure the seat is engaged in the seat stop, stand behind the machine and pull back on seat until fully engaged into stop.

Quick-Adjust Seat (if so equipped)

To adjust the position of the seat, move the seat adjustment lever to the left and slide the seat forward or rearward. Make sure seat is locked into position before operating the tractor.

Knob Adjustment Seat (if so equipped)

To adjust the position of the seat on models so equipped, loosen the two knobs on the bottom of the seat. Slide the seat forward or backward as desired. Retighten the two knobs.

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 16.

•Remove the hex lock-nut on the top of ball joint. See Figure 16.

•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 lock-nut 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 "toe-in" too far. Proper toe-in is between 1/16" and 5/16".

Front tire toe-in can be measured as follows:

•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.
