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 adjustment nut is too tight (preferred condition), the maximum forward travel speed is reduced.
Neutral Function Adjustment - Step 3
1.Move the FSC lever to the
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).
CAUTION
NEVER attempt to disconnect any safety devices or defeat the purpose of these safety devices.

Neutral Function Adjustment
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.
