These rotary cutters are designed for standard-duty applications such as weeds, grass, and light brush up to 1.5” in diameter. These cutters are designed to work with 15 to 65 hp tractors, cutters use a single spindle with two free-swinging blades, which reduce the shock of impact when a stationary object is contacted. A shear bolt through the input shaft or a slip clutch, if equipped, protects the gearbox and driveline from damage. Standard equipment includes driveline shields and clutch shields.
