Troubleshooting, Adjustment & Service

PARKING BRAKE ADJUSTMENT

1. Disengage the PTO, stop the engine, block the front
wheels, remove the ignition key, and engage the
parking brake.
2. Remove both control covers.
3. Locate the upper brake spring (A, Figure 21).
4. With the parking brake engaged, measure the com-
pressed spring length. The spring should be 2" to 2-
1/8" (5.0 - 5.4cm) when compressed.
5. If the spring is not within this range, jack up the rear
of the machine and secure with jackstands. Remove
both drive tires.
6. Locate the lower brake spring (A, Figure 22), adjust-
ment nuts (B, Figure 22) and adjustment link (C,
Figure 22).
7. Release the parking brake and turn the adjustment
nuts to compress or release the upper spring. Lock
the nuts against the adjustment link (C, Figure 22).
NOTE: Do not adjust the spring to be shorter than 2"
when compressed. This may damage the caliper case.
If this problem does not correct a braking problem,
see your dealer.

SUSPENSION HEIGHT ADJUSTMENT

If the rider tilts either side-to-side or front-to-rear, this
adjustment will level the frame with the ground.
Although this adjustment may not be necessary, it may
be required if additional weight (ie. a grass catcher) is
added to the frame or a drive tire is replaced.
To level the frame, loosen the jam nut (B, Figure 23) and
turn turn the height adjustment bolt (A, Figure 23)
COUNTER-CLOCKWISE to lower the corresponding
side of the frame, and CLOCKWISE to raise the frame.
NOTE: Perform this adjustment on a hard, level surface
such as a concrete floor. Making this adjustment will
affect the mower cutting height. For fine cutting height
adjustment, see your authorized dealer.
