Brush cutter, also known as a weed eater or brush saw, is a powerful, portable garden and agricultural tool used to cut through thick grass, weeds, small trees, and other tough vegetation that a standard lawn mower cannot handle. It features a motor (gasoline, electric, or battery-powered) at the end of a long shaft, with a rotating cutting head that uses either a nylon trimmer line or metal blades to clear foliage. They are typically shoulder-mounted or backpack-style for maneuverability and are designed for tasks like garden maintenance, landscaping, and clearing large plots of land.
