Operating Tips

For best results, do not cut wet grass.

New grass, thick grass, or wet grass may require a narrower cut.

For a healthier lawn, never cut off more than one-third of the total length of the grass.

Your lawn should be cut in the fall as long as there is growth.

Adjust ground speed according to the condition of the lawn.

Cutting Height Adjustment

Adjustment may be made by removing and moving axle bolts to desired position. Cutting heights will be raised as axle bolts are moved to a lower hole and lowered as axle bolts are moved to a higher hole in the deck All axle bolts must be assembled so that the cupped side of the washers are against the deck.
