Maintenance Instructions
4.
With the FSC in NEUTRAL-PARK, start the en-
gine. (Op erate first at idle and then normal op-
erating speed) and check for movement of
drive wheels.
NOTE: If the engine will not start, check and
ad just the neutral safety switch (refer to
Step 6 - FSC Switch - Neutral Adjustment).
5.
With the FSC in the NEUTRAL-PARK 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.
7.
Lower drive tires onto ground.
Step 4 - Full Forward Speed Adjustment
1.
Move the FSC to the full FORWARD speed posi-
tion.
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.

Step 5 - Straight Tracking Adjustment
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 Step 3 - Neutral Position
Adjustment and readjust).
2.
Check for straight ground tracking on a level sur-
face (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 on
the slow side by turning the adjuster nut clock-
wise. If straight tracking and neutral can not be
achieved, turn the adjuster nut counterclockwise
until neutral can be achieved.
4.
Lengthen the control rod of the faster side by
turning the adjuster nut counterclockwise to
match the slower side while maintaining the neu-
tral 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. Tight-
en the jam nut.
