Brakes And Brake Adjustment: Hydrostatic Gt - Cub Cadet 1000 SERIES Service Manual

Series 1000 and 1500
31.34. As the hydro control rod is pushed rearward, it
draws the cam (front) surface of the input arm
upward, forcing the neutral return arm forward,
applying more tension to the return spring.
See Figure 31.34.

31.35. The point that the neutral return arm draws the
input arm to is determined by the position of the
roller on the neutral return arm:
• If the roller is moved higher, the input arm will
move in the direction that causes forward drive.
• If the roller is moved lower, the input arm will
move in the direction that causes reverse drive.
31.36. The roller is moved up or down by rotating the
house-shaped eccentric that the neutral return
arm pivots on. See Figure 31.36.

31.37. Loosen the eccentric using a 1/4" Allen wrench,
and rotate it to adjust the roller up or down, as
required to center the input arm in Neutral.
31.38. Tighten the socket head cap screw to lock the
adjustment, and check to confirm that the adjust-
ment is correct by repeating step 23.25.
31.39. After confirming that the transaxle is correctly
adjusted:
• Adjust and reconnect the hydro control rod as
described in steps 23.28 through 23.30.
• Install the right rear wheel on the tractor, tighten-
ing the lug nuts to a torque of.
• Lower the tractor to the ground and test the
operation of the drive system in a safe area that
is free of hazards, obstacles, and by-standers.
• Install the cutting deck, test all safety features,
and return the tractor to service if everything
works properly.
32. BRAKES AND BRAKE ADJUSTMENT:
HYDROSTATIC GT
32.1. On hydrostatic garden tractors, most of the brak-
ing force is generated within the transaxle: when
in Neutral, with the brakes released, the tractor
will still be very difficult to push unless the relief
valve has been opened. The brake functions
mainly as a parking brake.
32.2. When properly adjusted, the brake should do
two things: it should stop and hold the tractor
when applied, and it should not drag when
released.
32.3. To check that the brakes hold the tractor:
• Open the relief valve.
• Set the parking brake.
• Attempt to push the tractor.
• The wheels should skid without rotating.
• If the brakes do not hold the tractor, the adjust-
ment needs to be tightened or the brakes need
to be repaired.
32.4. To check that the brakes do not drag:
• Open the relief valve.
• Release the parking brake.
• Attempt to push the tractor - it should move with
about 40 lbs of force. More force indicates drag.
• If the brakes drag, they need to be adjusted or
repaired.
