Brake Maintenance

Servicing the Brake

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 Parking Brake
Service Interval: Before each use or daily
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. Release the brake. The brake bars should lift off the
tires and the hand lever should travel forward to the
end of the slot in the control panel. Adjust the brake
if needed.
4. Engage the brake lever until the brake bars first contact
the tire (Figure 65).
5. Measure the gap from the front of the hand lever to the
end of the slot in the control panel when the brake bar
contacts the tire. This measurement needs to be 3/4
inch (19 mm). Adjust the brake if needed (Figure 65).
