Servicing the Brakes

Service Interval/Specification
Before each use, check brakes on both a level surface and
slope.
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 PTO.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Push the neutral/brake lock forward to set the brake.
4. 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 34.
5. Release the brake and move neutral/brake lock to the
neutral position. Move the machine lightly,
approximately 1/2 in. (13 mm). Wheels should rotate
freely.
6. If both conditions are met, no adjustment is required.
Adjusting the Brakes
The brake lever is on the upper control bar (Fig. 16). If the
parking brake does not hold securely, an adjustment is
required.
