The RoadRunner grading blade uses a serrated cutting edge that is designed to penetrate and crumble hard-packed materials. The rear blade is similar to that of a motor grader’s moldboard. The RoadRunner’s leveling characteristics result from its 5.5- or 6-foot skid bars, which have heat-treated wear strips. According to the manufacturer, the side panels eliminate windrows and the twin blades, operating on a slight angle, eliminate washboarding.
