How to Protect the Deck on Your Lawn Mower

Updated March 16, 2017

Lawnmowers do not come cheap, so taking care of this piece of equipment is of utmost importance. One of the prime ways to keep your mower operating properly is to protect the deck that covers your mower's engine and keeps debris from flying in all directions as you mow. Protecting your lawnmower's deck involves maintaining it regularly, after each mowing. This includes washing it from top to bottom as grass clippings can harden quickly and cause metal parts on the underside of your mower to corrode. Invest a few minutes protecting your mower deck and the return will be a longer lasting piece of equipment.

Empty the gas tank to prevent water from mixing with gasoline and damaging the motor. Take spark plug socket and remove the spark plugs from the connector to avoid any mishaps during the cleaning process.

Place lawnmower on its side. Take a water hose and spray blasts of water on the top and underside of the deck. Remove all clippings and debris.

Mix a bucket of soft detergent or car wash shampoo and hot water. Take a scrub brush and clean the deck. Rinse the deck. Dry completely.

Fill a spray bottle with a non-toxic lubricant. Coat the deck's underside with the lubricant. Non-stick vegetable cooking spray can be substituted.


Spark plugs are located in different spots on mowers, depending on the model. Check your owner's manual to determine the location of your spark plugs. When choosing a lubricant to protect the deck, an organic-based spray is recommended.
