PROBLEM TO BE SOLVED: To solve the problem of the conventional snow plow wherein during forwarding, a vehicle runs with a snow plow raised to a fixed position, and in consideration of obstruction to irradiation of a clearance lamp conformable with the security standard of a road transport vehicle disposed on the front of a driving cab of a snow plow vehicle, the height of the snow plow is limited, so snow can't be discharged on a high snow bank, and it is impossible to control the total quantity of discharged snow while the vehicle speed is kept. SOLUTION: This snow plow is divided into a low plow and a high plow, and a flap is disposed on the top of the high plow. In operation, the snow discharge height is adjusted by the elevating operation of the tip of the flap, and the snow discharge direction and distance are controlled by controlling the advance angle. In out of service, the tip of the flap is lowered not to be an obstacle to irradiation of the clearance lamp. COPYRIGHT: (C)2003,JPO
