Maintenance Instructions ADJUSTMENTS
3. Block the tractor up so the drive tires are off the
ground.
4. With the FSC in neutral, start the engine. (Op-
erate first at idle and then normal operating
speed) and check for movement of drive
wheels.
NOTE: If the engine will not start, check and ad-
just the neutral safety switch (see adjustment
below).
5. With the FSC in the neutral position and the en-
gine running, the wheels should not move. If a
drive tire is moving, the Control Rod on that side
is out of adjustment. Adjust that side to achieve
neutral. Now both transaxles are in the neutral
window.
Neutral Window
6. One at a time adjust the left and right Control
Rods to find the center of the neutral window.
Shorten the rods until the drive tire turns forward
then lengthen it until the drive tire turns in reverse
(approximately 1 turn). Position the rods 1/2 way
between forward and reverse. Tighten the jam
nuts.
7. Lower drive tires onto ground.
Full Forward Speed Adjustment - Step 4
1. Move the FSC to the full forward speed position.
2. Raise the body. The set screws in the left and
right Transmission Control Arms should not be
contacting the locating stud in the transaxle. If
they are, back the set screws out until they do
not touch.

Straight Tracking Adjustment - Step 5
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 back to the Neutral Position Adjustment -
Step 2 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 ob-
serve if the mower moves in a straight line (use
cement joint or other line on ground for refer-
ence).
3. If travel is not straight, shorten the control rod of
the slow side (adjust in 1/8 turn increments) to
match the faster side while maintaining the neu-
tral position. If straight tracking and neutral can
not be achieved, turn the control rod back to
where neutral can be achieved.
4. Lengthen the control rod of the faster side (ad-
just in 1/8 turn increments) to match the slower
side while maintaining the neutral position.
