6.17 Cleaning the Mower
The underside of the mower deck should be checked and cleaned twice daily, and more often if the grass
being mowed is lush or wet. The entire mower should be cleaned daily at the end of the work day.
Cleaning should be done with a leaf blower or low-pressure compressed air. Wash with water only when
necessary and do not use a pressure washer or nozzle as the water can enter electrical connections causing
an electrical short, rust and corrosion. When washing with water, do so when the unit has cooled down.
Washing a hot machine can cause various unseen system damage. If water is used for cleaning, immediately
dry it with a leaf blower or low-pressure compressed air. Once the wash is complete, always lubricate and
grease all applicable areas.
