Straight Ground Travel Adjustment - Walker T23 Operator's Manual

Maintenance Instructions
Neutral Function Adjustment
4. If drive wheels are moving, adjust the FSC neu-
tral stop by adjusting the FSC actuator rod (see
Neutral Function Adjustment photo). If the
drive wheels are moving backward, loosen the
jam nut and lengthen the FSC actuator rod by
turning the adjustment nut counterclockwise
(CCW). If the drive wheels are moving forward,
use the opposite clockwise (CW) adjustment.
5. At this point it may not be possible to adjust
both wheels stationary since the differential ad-
just 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.
6. Check the neutral safety switch for closure
and function with the FSC in neutral (the engine
will not start when the switch is open).

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
lever adjustment nut on the side of the mow-
er 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 the ground for reference).
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
mower tracks to the right, indicating the LH wheel
is moving too fast, tighten the LH adjustment nut.
