Service Interval/Specification
Before each use, check brakes for proper operation.
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
blade control (PTO) and push the neutral/brake lock
forward to set the brake.
2. Rear wheels must lock when you try to push the
machine forward or backward. Adjustment is required if
the wheels turn and do not lock. Refer to Adjusting the
Brake on page 30.
3. Release the brake and move neutral/brake lock to
neutral. Move the machine lightly, approximately
1/2 in. (13 mm). Wheels should rotate freely.

Adjusting the Brake
If the parking brake does not hold securely, an adjustment
is required.
1. Check the brake before you adjust it; refer to Checking
the Brake, page 30.
2. Release the parking brake; refer to Releasing the
Parking Brake, page 17.
3. To adjust brake, rotate the wing nuts on the brake rods
(Fig. 37). Rotate clockwise to tighten the brake and
counterclockwise to loosen the brake.
4. Position wingnut so the brakes will engage when the
drive levers are squeezed enough to place neutral/brake
lock forward and set the brake.

Brake, page 30.
Important With the parking brake released, the rear
wheels must rotate freely when you push the mower. If
brake action and free wheel rotation cannot be achieved
contact your service dealer immediately.
