Although it is recommended that you should rise off the lawn mower after each use, many people do not take the time to do so. During each use, fresh grass and other lawn weeds become trapped under the deck and build up over time. Excessive buildup under the lawn mower deck can eventually lead to unnecessary wear and tear on your riding lawn mower.
How To Clean Riding Lawn Mower Decks
Remove the deck from the riding lawn mower. Depending on the build of the individual mower, you may need additional tools.
Wear safety goggles in effort to avoid lose debris that could possibly fly into your eyes.
Scrape the dried dirt and grass using a putty knife. A putty knife is an appropriate tool to use because of its wide, flat surface.
Rinse the deck using a spray nozzle connected to the water hose. The spray nozzle allows the water to be more forceful than that of the unaided hose.
Allow the deck to dry completely before replacing it back on the riding lawn mower. Ample drying time will help to prevent rust spots.
