Maintenance

Note: The motion control lever needs to be in neutral while making any necessary adjustments.

7. Bring the motion control levers into the neutral position. Adjust pump control rod lengths by rotating the double nuts on the rod in the appropriate direction until the wheels slightly creep in reverse (Figure 33). Move the motion control levers to the reverse position and while applying slight pressure to the lever allow the reverse indicator springs to bring the levers back to neutral. The wheels must stop turning or slightly creep in reverse.

RH Motion Control Shown

1. Torque nyloc nut to 200 in-lb (16.7 ft-lb). Bolt must protrude past end of nyloc nut after torque. A T-40 Torx bit will be necessary to hold the stud from turning.

2. Most resistance (firmest feel)

3. Damper

4. Medium resistance (medium feel)

5. Least resistance (softest feel)

8.Shut off unit. Remove jumper wire from wire harness and plug connector into seat switch.

9.Remove the jack stands.

10.Raise the deck and re-install the height of cut pin.

11.Check that the machine does not creep in neutral with the park brakes disengaged.

Motion Control Damper Adjustment

The top damper mounting bolt can be adjusted to obtain a more desired motion control lever resistance. See Figure 34 for mounting options.

Motion Control Neutral Lock Pivot Adjustment
