19 Rear Suspension djustment POSITION #1 (FTORY SET) POSITION #2 The shock assembly can be adjusted in two ways to allow the operator to customize the ride according to the operator s weight and/or operating conditions. You have the option of adjusting the spring pre-load and/or 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 the machine on a flat, level surface. isengage the PTO, stop the engine and engage the parking brake. 2. Raise the rear of the machine and secure with jack stands. hock the front wheels to prevent the machine from rolling. 3. Remove the rear drive tires. 4. See Figure 40. Using the supplied spanner wrench (P/N: ), insert the tip of the wrench into the notch in the pre-load adjuster. While holding the wrench in place with both hands: Turn counter-clockwise to increase the pre-load; Turn clockwise to decrease the spring pre-load. Make sure both shocks are set to the same amount of pre-load. 5. Reinstall the rear drive tires. Torque the lug bolts to ft/lbs ( Nm). Remove the jack stands from under the machine. NOTE: Spanner wrench is located under the seat on the right-hand side of the machine. To adjust the upper mounting position: 1. Park machine on a flat, level surface. isengage the PTO, stop the engine and engage the parking brake. 2. Raise the rear of the machine and secure with jack stands. The jack stands must be under the bumper. hock the front wheels to prevent the machine from rolling. 3.
