Lawn mower racing is a form of motorsport where competitors race modified lawn mowers, usually of the ride-on or self-propelled variety. Original mower engines are retained but blades are removed for safety. The sport attracts all ages, and is usually entered into in a spirit of fun rather than extreme competitiveness, though many do take it quite seriously.
Lawn mower racing should not be confused with go-karting wherein lawn mower engines have often been used, especially amongst the amateur participants in go-karting. Lawn mower racing is based firmly around the use of both engines and chassis from regular model mowers.
