These cutters are designed to work with 15 to 65 hp tractors, and are available in 48”, 60”, and 72” widths. These 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.
