The invention relates to the field of agricultural machinery, and discloses a road grader which comprises a pulling frame assembly, a main frame assembly and a dragging frame assembly. The pulling frame assembly, the main frame assembly and the dragging frame assembly are sequentially connected with one another; a wheel subassembly is arranged on a second main frame of the road grader and is used as a travel mechanism of the road grader, a hydraulic subassembly is arranged on the second main frame, output ends of oil cylinders of the hydraulic subassembly are hinged onto wheel carriers, and output of the oil cylinders can be adjusted, so that the wheel carriers can be driven to rotate, and the altitude of a vehicle frame of the road grader can be adjusted; a dragging frame body is hinged to the rear side of the second main frame and is connected with the rear side of the second main frame by a pulling rope subassembly, starting ends of the pulling rope subassembly are connected onto the oil cylinders, and actions can be carried out on the dragging frame body via the pulling rope subassembly when the wheel carriers are adjusted by the oil cylinders. The road grader has the advantages that the altitude of the vehicle frame of the road grader can be increased via output of the oil cylinders when the vehicle frame is hung on the rear side of the road grader to be carried, and the pulling rope subassembly can be pulled by an oil cylinder subassembly, so that the dragging frame body can be rotationally turned up relative to the second main frame and even can be folded to be positioned above the second main frame, and scrapers can be prevented from being in contact with the ground when the road grader moves.
