Park Brake Adjustment - HUSTLER Super 104 General Service Manual

Park Brake Adjustment

Never work under the machine or attachment
unless it is safely supported with jack stands.
• Make certain machine is secure when it is
raised and placed on the jack stands.
• Use only certified jack stands. Use only
appropriate jack stands, with a minimum
weight rating of 2000 pounds (907 kg) to
block the unit up.
• Use in pairs only.
• Follow the instructions supplied with the
jack stands.
• The jack stands should not allow the
machine to move when the engine is running
and the drive wheels are rotating.
• Do not allow the wheels to come in contact
with the floor or any object that would permit
the unit to propel itself.
• To prevent injury stay clear and exercise cau-
tion when rotating the wheels.
1. Shut engine off, place steering control levers in the
park brake position, disengage deck clutch, remove
ignition switch key and disconnect negative battery
cable before doing any adjustments.
2. Raise the rear of the mower and block with certified
jack stands. The rear wheels need to be able to rotate
freely and clear of all obstructions.
3. Chock the front tires.
4. Position the steering control levers in the neutral
position.
NOTE: The front brake link is not to be adjusted.

6. Try and rotate the tire by hand. The tire should rotate.
Remember hydraulic oil resistance will prevent the tire
from rotating freely even with the bypass valves open.
There should be no resistance from the brakes at this
point.
7. Move the steering control lever to where it is just
inside (1/4" [6.35 mm]) the park brake slot. Figure 4-12
NOTE: When the steering control lever is against the out-
side edge of the slot, the brakes should not be engaged.
