摘要： A tracked snowplow particularly suited for use in very deep snow. A frame is carried on a tracked mover. The frame supports a triangular belt which is made up of a number of chains, stretched about rolls, and a large number of shovels which extend perpendicular to the chains. The shovels engage the links of the tracked mover as the shovels move along their lower run. The upper run of the shovels is angled rearwardly, and so as the snow is carried by the upper run, the weight of the snow helps drive the shovels, and the shovels, engaging the tracked mover, help drive it. From the upper run the snow is deposited into two secondary carrying belts which convey it to the sides of the snowplow for throwing out.
