1. Park the tractor on a smooth, level surface such as a
concrete floor. Disengage the PTO, engage the parking
brake, turn off the engine, and remove the ignition key.
2. Remove the PTO drive belt (See Mower Belt Replacement
for removal instructions).
3. Remove the hardware that secures the clutch anchor pad
to the PTO clutch.
4. Loosen the jam nut (H) installed on the spring anchor eyebolt
(G).
5. Loosen the adjustment nut (I) to release the majority of the
belt tension. Use caution and remove the nut to completely
release the tension.
6. Remove the old belt and replace it with a new one (A). Make
sure the V-side of the belt runs in the grooves of the
crankshaft pulley and pump pulleys (B & C). The back-side
of the belt should contact the idler pulley (D) on the idler arm
(E).
7. Reinstall the spring anchor eyebolt into the anchor tab and
loosely fasten the adjustment nut. Turn the adjustment nut
until a measurement of 8-3/4" (21,2 cm) is achieved from
the outside of the spring hooks on the belt tension spring
(F). Tighten the jam nut.
8. Reinstall the clutch anchor pad to the PTO clutch and secure
with the hardware previously removed.
9. Reinstall the PTO drive belt.
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 52. 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.
