REAR SUSPENSION ADJUSTMENT

The shock assembly can be adjusted in two ways to allow the operator to customize the ride according to operator’s weight and/or operating conditions. You have the option of adjusting the spring pre-load and/or the upper mounting position.

Items to consider before adjusting the suspension.

•Less spring pre-load should be used with light weight operators, which will provide a softer, more cushioned ride.

•More spring pre-load or upper mounting position #2 should be used with heavy weight operators, or when a rear-mount grass bagger system is installed, which will provide a stiffer, more rigid ride.

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.

To adjust the upper mounting position:

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.

4.Remove the upper shock mounting hardware and pivot the shock to the position #2 (see Figure 36). 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.
