Abstract

A snow groomer includes a movable platform, a prime mover mounted to the platform and a grooming drum rotatably driven by the prime mover for rotation in a direction opposite the traveling direction of the snow groomer. The grooming drum includes axially spaced apart and radially protruding ribs that extend circumferentially around the drum. The ribs include circumferentially spaced apart apertures and the apertures of each rib are aligned with the apertures of the other ribs. Elongated cutting teeth extend through the apertures of the ribs and have a cross-sectional area that is smaller than the apertures such that the cutting teeth are free to vibrate within the apertures as the drum rotates, thereby enhancing the pulverization of chunks of snow and ice.
