A self-powered rotary cutter-drum attachment—the RotoGrader—attaches to motor graders to pulverize gravel roads and shoulders and perform light surface milling of asphalt pavement. The attachment's rotary action provides uniform gradation. The RotoGrader has a 125-hp diesel power unit, a hydraulic pump and motor, single-lever joystick controls and attachment brackets. It is available with a 72-inch-wide, 18-inch-diameter cutter drum. Optional cutter drum widths are available.
