32.34. Press the brake pedal shaft as far outward as
possible, and pry the worn bushing out of the
bracket. See Figure 32.34.
Figure 32.34
NOTE: A pair of vice-grips and a plate can be
used to press the end of the shaft flush with the
edge of the bracket
NOTE: The inner bushing is a hex flange bush-
ing. The outer bushing is similar, but has one
open side. The "tooth" in the top facet of the
bracket that supports the bushing registers in
open side of the bushing.
32.35. Clean any corrosion or dirt from the surfaces
where the pedal shaft contacts the the bushing,
and slip the new bushings into place.

NOTE: Lubrication with grease may accelerate
busing wear. If lubrication is applied it should be
in dry form such as graphite or PTFE (Teflon).

32.36. Secure the inner bushing with a new cotter pin
and the flat washer that was previously
removed.
32.37. Move the pedal through it's range of travel to
check for bind. If binding is encountered:
• Bind in a portion if the travel may be caused by a
bent pedal shaft.
• Constant bind is likely to be caused by a bent
bracket.
• Also check for interference between the park
brake and cruise control interlocks.
32.38. Correct any binding condition.
32.39. Connect the brake rod to the brake pedal shaft,
and secure it with a new cotter pin.
32.40. After any brake service is performed, test the
brakes as described in steps 24.2 through 24.4,
then test-drive the tractor in a safe area that is
free of hazards, obstacles, and by-standers
before returning the tractor to service.

HYDROSTATIC GT
33.1. In normal use, the transaxle should last the life
of the tractor with minimal maintenance.
33.2. Because the transaxle dissipates heat through
air-cooling of the housing, it must be kept clean
of dirt and debris, and the cooling fan should be
replaced immediately if damaged.
33.3. Cleanliness is vitally important when doing any
service work that might expose the fluid or inter-
nal parts to any form of contamination. Clean
thoroughly around any fittings, parts, or seals
that are to be removed prior to removal.
33.4. Pressure washing is not recommended, and
may contaminate the transmission fluid. Dam-
age caused by contaminated fluid is not warrant-
able.
33.5. Before commencing internal repairs, eliminate
all possible external performance issues:
• Dragging brake
• Maladjusted linkage
• Partially open relief valve
• Slipping traction drive belt/ low engine speed
