Brake
Always set the parking brake when you stop the
machine or leave it unattended. If the parking brake
does not hold securely, an adjustment is required.
Checking the Brake
1. Park the machine on a level surface, disengage
the power take off (PTO), set the parking brake,
and turn the ignition key to “OFF” to stop the
engine. Remove the key.
2. Rear wheels must lock and skid when you try to
push the tractor forward. Adjustment is required
if the wheels turn and do not lock; refer to
Adjusting the Brake, page 28.
3. Release the brake and move the drive control rod
to the “PUSH” position; refer to Pushing the
Machine by Hand, page 20. Wheels should
rotate freely.
4. If both conditions are met no adjustment is
required.
Adjusting the Brake
1. Check the brake before you adjust it; refer to
Checking the Brake, page 28.
2. Release the parking brake; refer to Releasing the
Parking Brake, page 12.
3. To adjust the brake remove the cotter pin and
loosen the brake adjusting nut slightly (Fig. 28).
4. Carefully insert a 0.020” (.51 mm) feeler gauge
between the outer brake pad and rotor disk
(Fig. 28).
5. Tighten the brake adjusting nut until slight
resistance is felt on the feeler gauge when sliding
it in and out. Install cotter pin.
6. Check the brake operation again; refer to
Checking the Brake, page 28.
IMPORTANT: With the parking brake
released, the rear wheels must rotate freely
when you push the mower. If the 0.020”
(.51 mm) clearance and free wheel rotation
cannot be achieved contact your service
dealer immediately.
