25.8. As the hydro control rod moves back on the
input arm, it first moves a ground contact against
the reverse safety switch.
See Figure 25.8.
25.9. After the switch contacts the ground, the hydro
control rod reaches the end of the lost-motion
slot, and begins to push the arm forward, to the
reverse position. Excessive lost motion will
result in loss of ground speed in reverse.
25.10.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 25.10.
25.11. 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.
25.12.The roller is moved up or down by rotating the
house-shaped eccentric that the neutral return
arm pivots on.
See Figure 25.12.
25.13.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.
25.14.Tighten the socket head cap screw to lock the
adjustment, and check to confirm that the adjust
-
ment is correct.
25.15.After confirming that the transaxle is correctly
adjusted:
• Adjust and reconnect the hydro control rod if it
has been removed.
• Install the right rear wheel on the tractor if it was
removed.
• 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.
26. BRAKES AND BRAKE ADJUSTMENT:
HYDROSTATIC LT
26.1. 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.
