Figure 41. Suspension Adjustment
WARNING
Spring loaded components can kick back
causing injury.
Use two hands when adjusting the shock assemblies. This
will prevent the wrench from slipping while pressure is
being applied.
Rear Suspension Adjustment
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. 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 41. 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 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
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.
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 jack
stands. 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 position #2 (see Figure 41). 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.
