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 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. Make sure that for each pair of shocks that the left- hand and right-hand are set to the same amount of pre-load.

Use two hands when adjusting the shock springs. This will prevent the wrench from slipping while pressure is being applied.

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.
