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.

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.
