Tractor Box Blade attachments are used for smoothing and contouring land such as driveways or prepping land for gardens. It's a simple yet very useful tractor attachment that can be used for a lot of different things. In most cases a box blade attaches to a tractor by using a three point hitch. In the front of box blades you have retractable scarifiers which are used to break up hard ground while the back of the box blade has a blade on the outside and one on the inside. The EA XTreme heavy duty box blade is built from 3/8" thick steel and welded for maximum strength unlike some that are bolted together. The curved back on the box blade helps force the dirt to roll over and fill up the cavity for a smoother surface and better results.
