How to keep grass clippings from sticking to a mower deck.

Throughout the history of modern lawn care, there's been a quest to find the perfect solution to prevent grass buildup under the mower deck. Caked-on clippings disrupt the airflow essential for lifting the grass for a clean, even cut and for discharging the clippings. Grass buildup also encourages rust and corrosion.

The tips that follow discourage grass buildup. To get rid of the few clippings that manage to hang on, stick a garden hose into the discharge chute and spray them off; if your mower has a washout port, follow the instructions in the manual to run water through the port.  (You can add a port to a mower than doesn’t have one by installing a deck washout port kit.)
