A lawn mower is a piece of machinery used for trimming grass. It primarily consists of an engine and blades, with the blades rotating at the bottom of the machine to cut long grass on the lawn surface, resulting in a smoother and neater appearance. It is widely used in various places such as residential lawns, parks, and campuses, serving as an essential tool for maintaining the aesthetic and tidy look of the lawn. In recent years, with the continuous advancement of technology and increased focus on environmental protection, electric lawn mowers and solar-powered lawn mowers have also gained market recognition and application.
