A lawn mower, also known as a weed cutter, grass trimmer, or lawn trimmer, is a mechanical tool used for trimming lawns, vegetation, and so on. It consists of a cutting deck, an engine, running wheels, a traveling mechanism, blades, handles, and a control section.The cutting deck is mounted on the running wheels, with an engine installed on it. The blades are attached to the output shaft of the engine. By utilizing the high-speed rotation of the engine, the blades significantly increase their cutting speed, thereby saving time for weed control workers and reducing a substantial amount of human resources.
