To adjust the upper mounting position (Rear Shocks):
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 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 39). 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.
Suspension Adjustment
The shock assembly can be adjusted to vary the amount of
pre-load applied to the springs. This allows the operator to
maintain the ride height.
• Use less pre-load for light weight operators.
• Use more pre-load for 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. See Figure 39. 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 with both hands:
Turn clockwise to decrease the pre-load.
Turn counter-clockwise to increase the pre-load.
Make sure that for each pair of shocks that the left-hand
and right-hand are set to the same amount of pre-load.
NOTE: Spanner wrench is located under the seat. Rear tires
must be removed to adjust the rear suspension.
