The 300 series is our most light weight fixed tooth brush mulcher for 3-point hitch tractors. With low ground speed the MP360 Brush Fire brush mulcher will efficiently cut heavy vegetation and light brush using Green Teeth. The concave shaped carbide tip provides aggressive brush mulching action by chipping the brush bit by bit. Part of the secret of their performance is the ease of rotating the teeth so there is always a sharp edge to make mulching easier.
