A skid for use on a snow blower, where the snow blower includes an auger housing through which snow removed from an area is channeled. The skid includes a body that is secured to a vertical side wall of the auger housing. The body includes a sliding surface which assists the auger housing in sliding over snow-covered regions of the area being cleared; and a rolling surface which assists the auger housing to travel over snow-free regions of the area. A slot is provided in the sliding surface of the skid and a portion of the rolling surface projects for a distance below the sliding surface. An adapter plate may be positioned between the body and the side wall of the auger housing. The adapter plate enables the body to be secured to different makes of auger housing.
