Wheel Drive Spring Tension Adjustment

It may be necessary to increase wheel drive belt tension under certain operating conditions such as, wet grass, hilly terrain, or while pulling a sulky.

1.Stop engine and wait for all moving parts to stop. Engage parking brake. Remove key or spark plug wire(s).

2.Disengage neutral lock/park brake latches and release drive levers to lower spring force.

3.Remove the 5/16-18 inch whizlock nut securing the adjustment bolt to the drive wheel shield. Locate bolt assembly in the desired position as follows:

•Position A-Normal Conditions

•Position B-More Severe

•Position C-Most Severe

Note: Lever force is lowest with bolt assembly in Position A and will increase in Positions B and C (see Figure 27).
