Regular Maintenance

Suspension Adjustment

The shock assembly can be adjusted to vary the amount of pre-load applied to the springs. This allows the operator to maintain the ride height.

•Use less pre-load for light weight operators.

•Use more pre-load for heavy weight operators.

To adjust the spring pre-load:

1.Park machine on a flat, level surface. Disengage the PTO, stop the engine and engage the parking brake.

2.See Figure 39. Using the supplied spanner wrench (p/n 5022853), insert the tip of the wrench into the notch in the pre-load adjuster.

While holding the wrench with both hands:

•Turn clockwise to decrease the pre-load.

•Turn counter-clockwiseto increase the pre-load.

Make sure that for each pair of shocks that the left-hand and right-hand are set to the same amount of pre-load.

NOTE: Spanner wrench is located under the seat. Rear tires must be removed to adjust the rear suspension.

WARNING

Spring loaded components can kick back causing injury.

Use two hands when adjusting the shock springs. This will prevent the wrench from slipping while pressure is being applied.

To adjust the upper mounting position (Rear Shocks):

1.Park machine on a flat, level surface. Disengage the PTO, stop the engine, and engage the parking brake.

2.Raise the rear of the machine and secure with jackstands. The jackstands must under the bumper. Chock the front wheels to prevent the machine from rolling.

3.Position the jack under the cross member that ties the suspension arms together and slowly raise the rear suspension to relieve the pressure on the upper shock mounting bolts.

NOTE: This will require small adjustments to the jack’s position. The shock should move freely on the mounting bolt when the pressure is relieved.

4.Remove the upper shock mounting hardware and pivot the shock to the position #2 (see Figure 39). Adjust the jack to align the shock mounts to the shocks.

5.Reinstall the upper shock mounting hardware and tighten securely.

6.Remove the jack from under the suspension cross member.

7.Remove the jackstands from under the machine.
