Many consider a rear blade a must-have 3-Point attachment for a tractor. Push or grade soil and gravel, or even plow snow (we turned our rear blade backwards and successfully plowed snow on our gravel drive, too). Comes standard with a hydraulic angling kit so you can adjust your blade on the fly, right from the seat.
