REAR SUSPENSION ADJUSTMENT
The upper mounting position #2 (See Figure 1)
should be used when a rear-mount grass bagger
system is installed.
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 be 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 1).
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.
WARNING
Use two hands when adjusting the shock
springs. This will prevent the wrench from
slipping while pressure is being applied.
4. See Figure 1. 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 in place with one hand, turn
counter-clockwise
to increase the pre-load, turn
clockwise
to decrease the 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 85-95 ft/lbs. (115-129 Nm). Remove the
jackstands from under the machine.
NOTE: Spanner wrench is located under the seat on
the right-hand side of the machine.
