Troubleshooting, Adjustment & Service

WARNING

Use two hands when adjusting the shock

springs. This will prevent the wrench from

slipping while pressure is being applied.

Suspension Adjustment

The shock assembly can be adjusted to vary the

amount of pre-load applied to the springs. This allows

the operator to maintain the ride height.

Use less pre-load for light weight operators. Use

more pre-load for heavy weight operators. Adjust the

rear suspension height if additional weight (ie. grass

collector) is being added to the frame.

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 36. 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. Make sure that for each pair of shocks that

the left-hand and right-hand are set to the same

amount of pre-load.

E. Adjuster Bolt

NOTE: Spanner wrench is located under the seat.

Rear tires must be removed to adjust the rear

suspension.

NOTE: It is recommended that the rear suspension

be adjusted stiffer due to the added weight of the

collection system.

To adjust the rear suspension height:

1. Loosen the shock mounting bolt (B).

2. Loosen the top jam nut (C).

3. While holding the bottom jam nut (D) with a

wrench, turn the adjuster bolt (E) CLOCKWISE

to raise the rear suspension or COUNTER-

CLOCKWISE to lower the rear suspension.

4. Tighten the top jam nut (C).

5. Tighten the shock mounting bolt (B).

6. Repeat for other side.

NOTE: Both sides must be adjusted evenly to

prevent the rider frame from tilting to one side.
