Figure 27.  Front Suspension Adjustment

Front Suspension Adjustment

The shock assembly can be adjusted to vary the amount of pre-
load applied to the springs.  This allows the operator to cus-
tomize 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.

A

2. See Figure 27.  Turn the pre-load adjustment collar (A)

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

Adjustments and Service

Roller Bar Leveling

1. First level the mower deck using the procedure found in

MOWER DECK LEVELING.

2. With the mower installed, place the rider on a smooth, level

surface such as a concrete floor. Turn the front wheels so
they are straight.

3. Place the cutting height adjustment lever in the top adjust-

ment notch.

4. Measure the distance between the outside ends of the roller

bar and the ground. If there is more than 1/8” (3mm) dif-
ference between the measurements on each side, proceed
to step 5.

5. Locate the roller bar leveling hardware on the right side of

the mower deck (A, Figure 26).  Loosen the hardware and
raise or lower the roller bar until the correct level is
achieved, then tighten the hardware.  Repeat steps 4 & 5 if
necessary.
