Adjustments
Step 3 -
Neutral Function Adjustment
1. Securely block the tractor up so the drive tires
are off the ground.
2. Adjust the tracking adjustment nuts at the front
of both control rods so that 2 or 3 threads are
visible, then loosen the jam nuts on the ball
joints at the back of the control rods.

WARNING
The following adjustments are made with
the engine running. Keep all body parts
and tools away from rotating and hot com-
ponents, and secure all loose clothing.
3. With the FSC in
NEUTRAL-PARK,
start the
engine. With the engine at normal operating
speed, check for movement of the drive
wheels.
4. Using a wrench on one tracking adjustment
nut, rotate the control rod
clockwise
just until
the wheel on that side begins to
move for-
ward.
Then, counting the turns required,
rotate the control rod
counterclockwise
just
until the wheel stops and then begins
to move
in reverse.
Rotate the control rod back clock-
wise half the number of turns required to make
the wheel go from moving forward to reverse.
The transmission is now centered in the neu-
tral window. Tighten the jam nut on the ball
joint and repeat the same procedure on the
other transmission.
5. Turn off the engine, and then lower the drive
tires onto the ground.
Step 4 -
Straight Tracking Adjustment
1. Sit in the seat, start the engine, set throttle at
full speed, and with the FSC in the
NEUTRAL-
PARK
po sition check for movement of either
drive wheel (if either wheel moves backward
or forward, re fer to
and readjust).
2. Check for straight ground tracking on a level
surface (with hands off the steering levers).
Set the FSC at several different speeds and
observe if the machine moves in a straight line
(use cement joint or other line on ground for
reference).
3. If tracking is not straight, shorten the control
rod on the slower side by turning the tracking
adjustment nut clockwise. If straight tracking
and neutral are both achieved, proceed to the
next step. If straight tracking and neutral
cannot both be achieved, turn the tracking
adjustment nut on the faster side counter-
clockwise until neutral is restored.
