The box blade implement does not require PTO. Simply attach it to the 3-point hitch and get started. The implement can be raised or lowered to control the height of the cutting edge. Lower the cutting edge to cut, and raise it to dump the material. The heavy-duty, rear-mount box blade offers versatility for leveling, backfilling, grading and moving a variety of material. Heavy-duty, rear-mount cutting edges are strong enough to retain gravel, topsoil or other material. Adjustable and replaceable ripper shanks break up hard ground or compacted soil for easier moving. Steel cutting blade edges are reversible and replaceable to increase the life of your implement.
