Off-Season Storage

•Clean and lubricate mower thoroughly as described in the lubrication instructions. Do not use a pressure washer or garden hose to clean your unit.

•Refer to engine manual for correct engine storage instructions.

•Coat mower’s cutting blade with chassis grease to prevent rusting.

•Store mower in a dry, clean area. Do not store next to corrosive materials, such as fertilizer.
