Servicing the Brakes
Service Interval/Specification
Before each use, check the brakes for proper operation.
Always set the parking brakes when you stop the machine
or leave it unattended. If the parking brakes do not hold
securely, adjust them.
Checking the Brakes
1. Park the machine on a level surface, disengage the
blade control (PTO) lever, and push the neutral/parking
brake locks forward to set the brakes.
2. The rear wheels should lock when you try to push the
machine forward or backward. Adjust the brakes if the
wheels turn and do not lock. Refer to Adjusting the
Brakes, page 32.
3. Release the brakes and move the neutral/brake locks to
the Neutral position. Move the machine slightly,
approximately 1/2 in. (13 mm). The wheels should
rotate freely.
4. If both conditions are met, no adjustment is required.
Adjusting the Brakes
If the parking brakes do not hold securely, adjust them.
1. Check the brakes before you adjust them; refer to
Checking the Brakes, page 32.
2. Release the parking brakes; refer to Releasing the
Parking Brakes, page 19.
3. To adjust the brakes, rotate the wing nuts on the brake
rods (Fig. 37). Rotate the wing nuts clockwise to tighten
the brakes; rotate them counterclockwise to loosen
them.
