2. Visually inspect the linkage to confirm that it
functions properly. See Figure 5.14.

• Beneath the floor panel, on the right side of the
tractor there are two semi-circular latch plates.
• The outer latch plate rotates with the drive con-
trol pedals. The inner latch plate rotates with the
clutch/brake pedal.
2a. With the clutch/brake pedal fully released:
• The travel limit pin should be resting against the
front of the curved slot. See Figure 5.14.
• The rod that connects the clutch/brake latch
plate to the heavy brake actuator spring should
be slack. See Figure 5.15.
• The light brake pull-off spring should be holding
the brake arm back against the stop.

2b. Check the gap between the brake rotor and
the brake pads.
• There is a fixed pad in the transaxle housing.
• There is a moving pad in the brake caliper.
• Wiggle the brake rotor slightly, and attempt to
insert a .015" (.38mm) feeler gauge between the
rotor and either pad.
2c. Adjust the gap, if necessary, so that the
feeler gauge slips between the pad and the
rotor with light pressure. See Figure 5.16.
• If adjustment is necessary, remove and discard
the cotter pin that locks the adjusting nut.
• Turn the nut to adjust the gap.
• Apply and release the brake pedal, then re-
check the gap.
• If the gap is consistent, install a new cotter pin to
secure the adjustment nut.

2d. If the brake seems to be sticking, or the
rotor is discolored from dragging, remove
the brake yoke for repair or replacement.
2e. Confirm that the drive belt is under tension
when the brake is released.
2f. Set the brake. The drive belt should be
slack.
2g. Re-test the operation of the brakes before
returning the tractor to service.
NOTE: The hydrostatic transaxle creates it's
own braking force from the hydraulic pressure in
the hydraulic motor. The brakes are used more
as a park brake use than service brake. They
generally show little wear over the life of the trac-
tor.
