INSTALLATION
Installation
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 jack stands 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 jack stands 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.
More spring pre-load 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.
2. Raise the rear of the machine and secure with
jack stands. Chock the front wheels to prevent the
machine from rolling.
3. Remove the rear drive tires.
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 jack
stands from under the machine.
NOTE: Spanner wrench is located under the seat on
the right-hand side of the machine.
