Checking the Parking Brake

3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.

tractor forward, you do not need to adjust the parking
brake. Adjust the parking brake if the wheels turn and
do not lock; refer to Adjusting the Parking Brake on
page 24.

3. Remove the cotter pin that secures the brake adjusting
nut and slightly loosen the nut (Fig. 21).
4. Insert a 0.015 in. (0.38 mm) feeler gauge between the
brake disc and brake puck (Fig. 21).
5. Tighten the nut until you feel a slight resistance on the
feeler gauge when you slide it in and out.
6. Install a new cotter pin and attach the brake arm spring.
7. Check the parking brake operation again; refer to
Checking the Parking Brake on page 24.

cannot achieve the .015 in. (0.38 mm) clearance and free
wheel rotation, contact an Authorized Service Dealer
immediately.
