Maintenance Instructions
ADJUSTMENTS
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.
4. With the body lowered and the FSC in
NEU-
TRAL-PARK,
start the engine. With the engine
at normal operating speed, check for movement
of the drive wheels.
5. Lift the body to access the steering adjustment
components.
NOTE:
It may be necessary to tighten the FSC
friction adjustment if the transmissions are
moved out of neutral when the body is raised.
Refer to
Step 7 -
Forward Speed Control Friction
Adjustment
later in this section for location of the
FSC friction adjustment nut.
6. Using a wrench on one elastic stop nut, rotate
the control rod
clockwise
just until the wheel on
that side begins
to move
forward.
Then, count-
ing the turns required, rotate the control rod
counterclockwise
just until the wheel stops and
then begins
to move in reverse.
Rotate the con-
trol rod back clockwise half the number of turns
required to make the wheel go from moving for-
ward to reverse. The transmission is now cen-
tered in the neutral window. Tighten the jam nut
on the ball joint and repeat the same procedure
on the other transmission.
7.
Turn off the engine, and then lower the drive tires
onto the 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
Step 3 -
Neutral Position Adjust-
ment
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.
