A lawnmower is a machine used to cut grass to an even height, making lawns and gardens look neat and tidy. It typically consists of a blade that rotates rapidly to trim the grass, and it can be powered by electricity, gasoline, or even manually pushed. There are various types of lawnmowers, including push mowers, riding mowers, and robotic mowers. Each type serves different needs, from small residential lawns to large commercial properties. Regular mowing helps maintain healthy grass and prevents weeds from taking over the yard.
