Discover heavy-duty box graders and box blades, the go-to tool for spreading large quantities of gravel, shingle and topsoil. The ripper blades featured on some models let you delve into pothole-filled gravel roads to break up the surface before levelling them. Gone are the days of manually shovelling shingle/gravel into wheelbarrows, dumping it in piles, then raking it flat. Our box graders will both move the aggregate and level it at the same time.
