ABSTRACT:
Apparatus and method for snow removal is disclosed. A wheeled frame having an adjustable suspension capable of operation in a snow removal and a transport position is provided. The frame is open at one end and includes a hitch at the other end for connection to a prime mover. Two vertical snow cutting knives are connected to the frame near the open end thereof with a horizontal snow cutting knife connecting the vertical knives proximate the ground. A snow moving blade is pivotably supported to the frame and actuated by a pair of double acting cylinders to move up and down. In operation the open end of the apparatus is pushed into a pile of snow and snow is cut loose by the knives. The blade is then lowered into close proximity with the ground and near the open end of the frame whereby a selected quantity or block of snow may be pulled or towed away.
