2. Install the pins (C, Figure 15) into the holes.
3. Lower the rear of the bed, pressing down firmly to secure
with the locking clips (D, Figure 15).
CAUTION
To avoid injury, assistance is required when removing or
installing the cargo bed.
Suspension Adjustment (if equipped)
The shock assemblies (A, Figure 16 - front shown, rear
similar) 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, pivot the ground speed levers out to the START/
PARK position, and stop the engine.
2. Turn the pre-load adjustment collar (B, Figure 16) to a
higher notch (-) to decrease the pre-load, or to a lower
notch (+) to increase the pre-load. Make sure all shocks
are set to the same amount of pre-load.
