These rotary cutters are designed for medium-duty applications such as weeds, grass, and brush up to 2” diameter.  These cutters are designed to work with 32 to 90 hp tractors, and are available from 48” to 84″ 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.
