Maintenance Instructions ADJUSTMENTS
NOTE: If the engine will not start, check and ad-
just the neutral safety switch (refer to Neutral
Switch Adjustment - Step 6).
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.

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 halfway
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
position check for movement of either drive
wheel (if either wheel moves backward or for-
ward, refer to the Neutral Position Adjustment -
Step 3 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 mower moves in a straight line (use cement
joint or other line on ground for reference).
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 (adjust
in 1/8 turn increments) to match the slower side
while maintaining the neutral position.
5. If the forward travel is straight throughout the
speed range, except at maximum speed - place
the FSC in full forward, turn the set screw in the
Transmission Control Arm, of the faster side, in
until it contacts the hydro stud. (Turning the set
screw in slows the wheel.) Turn the set screw in
an additional 1/8 turn. Recheck for equal full for-
ward speed. Adjust this set screw until equal full
forward speed is achieved. Tighten the jam nut.
