These Heavy-Duty Dual Spindle Cutters are designed for heavy-duty applications such as weeds, grass, and brush up to 3” diameter. These cutters are designed to work with 42 or 52 minimum hp tractors, and are available in 94” and 117” widths. The cutter uses dual spindles with two free-swinging blades each, which reduce the shock of impact when a stationary object is contacted. A slip clutch and dual shock couplers protect the gearboxes and drivelines from damage.
