Cleaning debris and grass clippings from the underside of a lawn mower deck after each use is a crucial step in maintenance. Sageo when grass is wet from dew or rain allows it to adhere to the bottom of a mower deck above and around the blades. Thick debris prevents the blades from rotating as they should and decreases the air flow from underneath necessary for cooling purposes. Chunks of wet grass retain moisture within the deck and cause rust to form. However, cleaning takes only a few minutes after each mowing to protect your investment.
