Auxiliary unit for road grading intended for attachment to a vehicle, preferably a tractor excavator (1) or the like. Characterizing for the invention is that the unit includes a frame and a working member (22) carried by said frame, the working member being such as a road grader blade, and in that the frame is removably connected to the vehicle (1) partly by means (2, 6, 32) guiding the frame and partly by the frame itself and thus means (3, 4, 16) regulating the level of the blade. Said level regulating means partly comprises extensible struts (16, 17) or hydraulic cylinders, and partly supporting legs (3, 4) associated with the tractor excavator. With the aid of said level regulating means the setting of the blade in relation to a ground plane can be finely adjusted. At the same time, the unit may be steered with the aid of the steering means (2, 6, 32) associated with the vehicle. |
