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.
