6. Remove the old belt and replace with a new one (H). Make
sure the V-side of the belt runs in the grooves of the
adjustable idler pulley (I), front stationary idler pulley (J),
both transmission pulleys (K) and the crankshaft pulley (L).
7. Reinstall the spring anchor eyebolt into the spring anchor
tab and loosely fasten the adjustment nut.
8. Tighten the nut until the spring achieves a coil-to-coil
measurement of 8-5/8" (21.9 cm).
9. Tighten the jam nut.
10. Reinstall the clutch anchor pad to the PTO clutch and secure
using the hardware previously removed. Reconnect wire
harness to the PTO clutch.
11. Reinstall the PTO belt. See Mower Drive Belt Replacement
for instructions.
Rear Suspension Adjustment
The shock assembly can be adjusted in two ways to allow the
operator to customize the ride according to operator’s weight
and/or operating conditions. You have the option of adjusting
the spring pre-load and/or the 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 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.
Chock the front wheels to prevent the machine from rolling.
3. Remove the rear drive tires.
WARNING
Use two hands when adjusting the shock springs. This will
prevent the wrench from slipping while pressure is applied.
4. See Figure 56. 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.
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 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 56). 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.
