Brush cutter is a powered gardening or agricultural tool used for cutting through tough vegetation like overgrown grass, weeds, shrubs, and small trees, especially in areas inaccessible to lawn mowers. It typically features a rotating blade powered by a gasoline engine, though electric and battery-powered options are also available. Brush cutters are versatile, allowing for various attachments to tackle different types of vegetation and even perform tasks like tilling or pumping water.
