The snow plough has a rigid interchangeable blade (1) of varied shape and size which is partly curved and hinged to the chassis (2). The chassis includes tubular casings (7) in which slide two 90 deg angled shafts (6) which support the blade and orientate it relative to the front wheels (3) in a vertical plane at an angle between 0 deg and 135 deg . The angle is determined by the respective displacement amplitude of each shaft in the casings. The blade includes an assembly constituted by a runner (4) and a tubular guide (5) enabling automatic orientation of the blade during displacement of the axles in the casings. The blade is provided in its base with a plastics or rubber band.
