a. Loosen the jam nut on each end of the tie-rod.
b. Turn tie-rod counterclockwise (lengthening the
distance between the steering lever and hydrostatic
transmission) several times.
If the wheel is moving in a reverse direction:
a. Loosen the jam nut on each end of the tie-rod.
b. Turn tie-rod clockwise (decreasing the distance
between the steering lever and hydrostatic
transmission) several times.
8. Start engine.
9. Move steering levers from Forward to Reverse several
times. Then return steering levers to neutral position.
10. Shut off engine.
11. If wheel is not moving, tighten jam nuts on tie-rod. The
adjustment is complete.
12. If wheel is still moving, repeat steps 7 through 12.
ADJUSTING UNIT TO TRACK STRAIGHT
Check and adjust tire pressure. Increase pressure on side
unit tracks to. DO NOT exceed maximum recommended tire
pressure. See SPECIFICATIONS on page 34 for correct tire
pressure.
If tire pressure adjustment does not solve tracking problem,
adjust the limiter bolts on the stop bracket (figure 25). Front
bolts adjust forward and rear bolts adjust reverse. Lengthen
the limiter bolt (move closer to lever) on side which is too
fast.
STEERING LEVER HANDLE HEIGHT
ADJUSTMENT
The handles have three height positions (figure 26).
1. Remove spacer, handle, and eccentric spacer from
steering lever.
NOTE: Position the right and left handles at the same
height.
2. Install spacer, handle, and eccentric spacer in the
appropriate height position. Do not tighten nut holding
eccentric spacer.
3. Turn eccentric spacer until the right and left handles are
the same height. Tighten nut.
PARKING BRAKE ADJUSTMENT
The parking brake might need adjustment over time and
after new brake pads have been installed.
NOTE: After installing new brake pads in calipers, they must
be burnished by driving for a short distance (about 100 feet)
with the brake on. To do this, bring parking brake lever
part-way up while driving normally (in a straight line).
Check Adjustment
NOTE: Be sure to check parking brake on both sides of unit
(figure 27).
NOTE: The clearance between jam nuts and trunnion
should be:
• 1-1/2 in. (3.81 cm) for models with serial numbers below
000500.
• 1-1/4 in. (3.2 cm) for models with serial numbers 000500
and above.
Adjusting the parking brake
1. Engage parking brake.
2. Turn jam nuts counterclockwise until the spring is
completely extended and there is no pressure on the
spring.
WARNING: Prior to adjusting the tracking of the
unit, shut off engine, engage parking brake, and
remove the ignition key.
