Adjusting the Parking Brake

Service Interval: After the first 100 hours
Every 500 hours thereafter
Check to make sure that the brake is adjusted properly.
Follow this procedure after the first 100 hours or when you
remove or replace a brake component.
1. Drive the machine onto a level surface.
2. Disengage the blade-control switch (PTO), move the
motion-control levers to the neutral-locked position,
and set the parking brake.
3. Stop the engine, wait for all moving parts to stop, and
remove the key.
4. Raise the back of the machine up and support the
machine with jack stands.
DANGER
Mechanical or hydraulic jacks may fail to
support machine and cause a serious injury.
• Use jack stand when supporting machine.
• Do not use hydraulic jacks.
5. Remove the rear wheels from the machine.
6. Remove any debris from the brake area.
7. Rotate the drive-wheel release handle to the released
position. Refer to the Using the Drive-wheel Release
Valves section in Operation.
8. Measure the overall length of the compression spring.
The correct length should be between 3.8 and 4.0
cm (1-1/2 and 1-9/16 inches). If the spring length is
within this range, no adjustment is needed. If it is not,
proceed to step 9.

locknut until the spring length is between 3.8 and 4.0
cm (1-1/2 and 1-9/16 inches); refer toFigure 71. Do
not allow the cable to turn when the nuts are being
loosened.
