A snow plow composed of a central blade and of two wing blades which are laterally hinged to the end of the main blade for wing blade angular adjustment forwardly and rearwardly of the main blade from a position and alignment with the same. Furthermore, the level of each wing blade with respect to the main blade can be adjusted. Also, tilt motion of the laterally outward end portions of the wing blades either upwardly or downwardly is also possible. Each blade consists of a flat panel and its bottom edge carries a striker lip which can pivot rearwardly during forward movement of the plow upon the blade striking an obstacle. The snow plow is supported by a structure in front of a vehicle having forward lifting and tilting arms, this structure allowing a snow plow to laterally tilt within a limited angle in accordance with the transverse inclination of the surface being plowed. Upon slight rising of the snow plow, its forward pitch angle automatically increases to a pre-determined limit.
