LaneShark Rotary Cutter w/15-20GPM Motor, 44" Cutting Width, 2-3" Capacity

The Lane Shark LS4-15-20 Rotary Cutter is a high-flow, front-mounted cutting solution designed for aggressive trimming and brush control in hard-to-reach areas. Built to mount directly to your tractor’s front-end loader (SSQA or JD hook & pin), it gives you clear visibility and control with vertical and offset cutting positions (25°–55°). With a 44" cutting width and a high-capacity 15–20 GPM motor, this model is ideal for operators who want faster cutting performance and the ability to handle tougher material—because sometimes “light trimming” turns into “well, that got out of hand.”
