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:
