SUSPENSION ADJUSTMENT (SELECT MODELS)

The shock assembly can be adjusted to vary the amount of pre-load applied to the springs. This allows the operator to customize the ride according to operator’s weight and operating conditions.

LESS PRE-LOAD:

•Light operator weight

•Softer, more cushioned ride

•Best for relatively flat terrain

MORE PRE-LOAD:

•Heavy operator weight

•Stiffer, more rigid ride

•Better handling and greater stability on hilly terrain

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 28. Turn the pre-load adjustment collar

(A) CLOCKWISE to increase the pre-load, turn COUNTER-CLOCKWISE to decrease the pre- load. Make sure both front shocks are set to the same amount of pre-load. Make sure both rear shocks are set to the same amount of pre-load.

NOTE: After adjusting the front shock assembly, move the o-ring against the adjustment collar to prevent the collar from loosening during operation.
