Park Brake Adjustment
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.
Figure 6-10
5. Open the hydraulic pump’s bypass (tow) valve, on the
side that is being adjusted, by turning the bypass valve
to open. Figure 6-11
6. Try to 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" [6.35mm]) the park brake slot. Figure 6-12
NOTE: When the steering control lever is against the
outside edge of the slot, the brakes should not be
engaged.
8. Rotate the tire. If the brake is adjusted properly the tire
will still rotate but friction will start to become
noticeable here. However, if no brake resistance is
noticed, the brake needs adjusted as follows:
a. Loosen the brake linkage jam nuts. (Figure 6-13)
Rotate the tire and at the same time rotate the
turnbuckle to shorten the length of the brake linkage
to increase the brake pressure. When you feel the
brake begin to engage, stop adjusting the turnbuckle.
Re-tighten the jam nuts on the turnbuckle.
b. Place the control lever in the park brake slot. The tire
should not rotate when the control lever is in the park
brake position.
Figure 6-12
c. Place the control lever in the neutral position. The tire
should rotate freely.
9. Close the hydraulic pump’s bypass valve. Figure 6-11
10. Repeat steps 4 through 9 for the other side.
11. Check to make sure all tools or obstructions are
removed from under the mower.
12. Remove the chocks from the front tires.
13. Raise the rear of the mower and remove the jack
stands. Lower the mower.
14. Reconnect the negative battery cable.
15. Lower and secure the seat platform.
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
caution when rotating the wheels.
