Claims2
A method of removing a layer of snow frozen into a form of an ice plate and lying on the ground in front of a travelling vehicle, comprising initially breaking up a part of said ice plate by discharging into said ice plate high velocity water from a plurality of nozzles mounted on and extending horizontally across the front width portion of the vehicle, in a forwards and downwards direction at an angle in a range of 45.degree. to 60.degree. with respect to a surface of the ground and at a pressure of not less than 140 Kg/cm.sup.2, and then varying said angle to a range of 20.degree. to 30.degree., while continuing to discharge said water into a gap between said ice plate and said ground surface to strip said ice plate from said surface of the ground.
