Steering Lever End Play Adjustment; Neutral Function Adjustment; Straight Ground Travel Adjustment - Walker MS (13 HP) Owner's Manual

Maintenance Instructions
Steering Lever End Play Adjustment - Step 2
1. Position the FSC lever to the most FORWARD
position.
2. Loosen the adjustment nut on each steering le-
ver actuator until end play develops between the
lever actuator and the adjustment nut (sliding on
transmission control rod).
3. Hold the actuator back as shown (against the
spring pressure) and tighten the nut to the point
where the end play is removed and then tighten
two additional turns.
IMPORTANT: If the adjustment nut is too loose
(end play exists), excessive loads are placed on
transmission internal control stops. If the adjust-
ment nut is too tight (preferred condition), the max-
imum forward travel speed is reduced.
Neutral Function Adjustment - Step 3
1. Move the FSC lever to the NEUTRAL-PARK po-
sition (rear travel limit).
2. Start the engine (operate first at idle and then
normal operating speeds) and check for move-
ment of the drive wheels.
NOTE: If the engine will not start, check and ad-
just the neutral safety switch (see item 4 below).
NEVER attempt to disconnect any safety
devices or defeat the purpose of these
safety devices.

Clevis
3. If drive wheels are moving, stop the engine and
adjust the FSC neutral stop by adjusting the
FSC actuator clevis (refer to Neutral Function Ad-
justment photo for clevis location). If the drive
wheels are moving backward, remove the cotter
pin and clevis pin and screw the clevis forward.
If the drive wheels are moving forward, screw the
clevis backward. Restart the engine and check
for wheel movement (several "trial and error" ad-
justments may be required). At this point it may
not be possible to adjust both wheels station-
ary since the differential adjustment has not
been made. (This is covered by the Straight
Ground Travel Adjustment - Step 4.) In this case,
the neutral adjustment should be made for one
wheel stationary and the other moving forward
slightly.
4. Check and adjust the neutral safety switch for
closure and function with the FSC in neutral (the
engine will not start when the switch is open).
Use the panel nuts on the switch body to adjust
switch position for closure in neutral. Refer to ad-
justment description for Safety Switches in this
section.
Straight Ground Travel Adjustment - Step 4
1. Sit in the seat, start the engine (operate at normal
speed), and with the FSC in the NEUTRAL-
PARK position check for forward movement of
either drive wheel (if either wheel moves back-
ward, refer back to Neutral Function Adjustment
- Step 3 and readjust). Tighten the steering le-
ver adjustment nut on the side of the mower
with the wheel moving forward until wheel
movement stops.
2. Check for straight ground track 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).
NOTE: The final tracking adjustment is made
with the mower moving, since the adjustment is
quite sensitive and is more easily "fine tuned"
when moving.
3. If travel is not straight, tighten the adjustment
nut that is on the same side of the mower as
the wheel that is moving too fast, e.g., the mow-
er tracks to the right, indicating the LH wheel is
moving too fast, tighten the LH adjustment nut.
