Suspension Adjustment
The shock assembly can be adjusted in two ways to
allow the operator to customize the ride according
to the 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 or upper shock mounting
positions 1 or 2 should be used with light weight
operators, which will provide a softer, more
cushioned ride.
• More spring pre-load or upper shock mounting
positions 4 or 5 should be used with heavy weight
operators, which will provide a stiffer, more rigid
ride.
To adjust the spring pre-load:
1. Park the machine on a flat, level surface.
Disengage the PTO, stop the engine and engage
the parking brake.
2. See Figure 33. 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 with both hands, turn
CLOCKWISE to decrease the pre-load, turn
COUNTER-CLOCKWISE to increase the pre-load.
To adjust the upper mounting position:
1. Park the machine on a flat, level surface.
Disengage the PTO, stop the engine and engage
the parking brake.
2. Remove the upper shock mounting hardware (A,
Figure 33) and move the shock towards the front
of the machine to soften the ride or move the
shock towards the rear of the machine to stiffen
the ride.
3. Reinstall the upper shock mounting hardware.
