Troubleshooting

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.

 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.

 4.  See Figure 36. 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.

 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.

 4.  Remove the upper shock mounting hardware and 

pivot the shock to the position #2 (see Figure 36).  
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.
