Checking the Parking Brake
1. Park the tractor on a level surface.
2. Disengage the blade control (PTO) and set the
parking brake.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Move the drive control wire to the Push position;
refer to Pushing the Tractor Manually.
5. If the rear wheels lock and skid when you push
the 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.
Adjusting the Parking Brake
1. Check the parking brake before you adjust it; refer to
Checking the Brake.
2. Remove the brake arm spring (Figure 31).
3. Remove the cotter pin that secures the brake
adjusting nut and slightly loosen the nut (Figure 31).
4. Insert a 0.015 inch (0.38 mm) feeler gauge between
the brake disc and brake puck (Figure 31).
5. Tighten the nut until you feel a slight resistance on
the feeler gauge when you slide it in and out.

mm) clearance and free wheel rotation, contact
an Authorized Service Dealer immediately.
