Maintenance

CAUTION

Raising the mower deck for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the unit to fall, which could cause injury.

Do Not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support.

1.This adjustment must be made with the drive wheels turning. First raise the rear of machine up and support with jack stands (or equivalent support) just high enough to allow the drive wheels to rotate freely.

2.Unhook seat latch and tilt seat forward.

3.Remove the electrical connection from the seat safety switch, located directly to the left of the seat switch assembly beside the hydraulic oil reservoir.

Temporarily install a jumper wire across the terminals in the connector of the main wiring harness.

4.Run the unit at least 5 minutes with the drive levers at full forward speed to bring hydraulic system oil up to operating temperature.

5.Loosen lock nuts from the ball joints at each end of the pump control linkage (Figure 27).

7.The reverse indicator spring must be correct before the following adjustments can be made. See the Reverse Indicator Adjustment section.

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

The left rod assembly controls the left wheel and the right rod assembly controls the right wheel.

8.Bring the motion control lever into the neutral position. Adjust RH pump control rod length by rotating the double nuts on the rod in the appropriate direction until the wheels slightly creep in reverse (Figure 27). Move the motion control lever to the reverse position and while applying slight pressure to the lever allow the reverse indicator spring to bring the levers back to neutral. The wheel must stop turning or slightly creep in reverse. When adjustment is complete, tighten lock nuts onto ball joints.

9.Bring the LH motion control lever into the neutral position. Adjust the LH pump control rod length by rotating the tracking adjustment knob in the appropriate direction until the wheels slightly creep in reverse. Move the motion control lever to the reverse position and while applying slight pressure to the lever allow the reverse indicator spring to bring the levers back to neutral. The wheel must stop turning or slightly creep in reverse (Figure 28).
