ADJUSTMENTS<br />
Straight Ground Travel Adjustment - Step 4<br />
1. Sit in the seat, start the engine (operate at normal<br />
speed), and with the FSC in the NEUTRAL-<br />
PARK position check for forward movement<br />
of either drive wheel (if either wheel moves<br />
backward, refer back to Neutral Function Adjustment<br />
- Step 3 and readjust). Tighten the<br />
steering lever adjustment nut on the side of<br />
the mower with the wheel moving forward<br />
until wheel movement stops.<br />
2. Check for straight ground track on a level surface<br />
(with hands off the steering levers). Set<br />
the FSC at several different speeds and observe<br />
if the mower moves in a straight line (use<br />
cement joint or other line on the ground for reference).<br />
NOTE: The final tracking adjustment is made<br />
with the mower moving, since the adjustment is<br />
quite sensitive and is more easily “fine tuned”<br />
when moving.<br />
3. If travel is not straight, tighten the adjustment<br />
nut that is on the same side of the mower as<br />
the wheel that is moving too fast, e.g., the<br />
mower tracks to the right, indicating the LH wheel<br />
is moving too fast, tighten the LH adjustment nut.<br />
Forward Speed Control Friction Lock<br />
The FSC friction lock is adjusted to hold the selected<br />
forward speed when the steering levers are<br />
moved and yet the friction is not too heavy to make<br />
moving the control difficult (too much friction).<br />
The procedure for checking and adjusting the FSC<br />
friction lock is as follows:<br />
FSC Actuator<br />
Friction Washer<br />
Friction<br />
Adjustment Nut<br />
Forward Speed Control Friction Lock<br />
1. Place the FSC in the full FORWARD position<br />
and pull both steering levers back; the FSC lever<br />
should not move. If the FSC lever moves<br />
back when the steering levers are pulled back,<br />
the friction needs to be increased.<br />
2. With the steering levers held back, move the<br />
FSC lever back from the FORWARD position.<br />
With a proper amount of friction adjusted, the<br />
FSC lever should move back with a slight<br />
amount of resistance (friction). If the FSC lever<br />
movement is “stiff”, the friction needs to be<br />
decreased.<br />

3. The FSC friction is increased or decreased by<br />
tightening or loosening the friction adjustment<br />
nut. Loosen or tighten the nut and check<br />
the control function until conditions of both<br />
steps 1 and 2 (above) are met.<br />
