SPEED BALANCING ADJUSTMENT

WARNING

DO NOT adjust the rider for a faster overall speed forward or reverse than it was designed for.

If the rider veers to the right or left when the ground speed control levers are in the maximum forward or reverse position, the top speed of each of these levers can be balanced by turning the adjustment bolt(s) (A

&C Figure 25). Only adjust the speed of the wheel that is traveling faster.

TO REDUCE THE SPEED OF THE FASTER WHEEL

1.Loosen the jam nut securing the top speed adjustment bolt (A, C).

2.Turn the top speed adjustment bolt COUNTER- CLOCKWISE to reduce the speed.

3.Retighten the securing nut when adjustment is complete.

CUTTING HEIGHT ADJUSTMENT

The cutting height adjustment pin (A, Figure 26) controls the mower cutting height. The cutting height is adjustable between 1-1/2” (3,8 cm) and 4-1/2” (11,4cm). Pulling the lever back fully locks the control in transport position.

To adjust cutting height:

1.Pull the adjustment lever (B) back fully until it locks in transport position.

2.Remove the cutting height adjustment pin (A) and insert it into the desired hole.

3.Pull back on the adjustment lever (B), squeeze the smaller transport release lever (C), and allow the lever to move forward until it is supported by the cutting height adjustment pin (A).

NEUTRAL ADJUSTMENT

If the unit creeps forward or backward with the control levers in their neutral positions, see your dealer.
