Abstract

A snow plow blade edge shoe comprising an elongate flattened C-channel profile. The snow plow blade edge show comprises a channel window opening to a blade cavity configured for seating a cutting edge of a snow plow assembly therein. In some embodiments, the edge shoe is secured by fasteners to the snow plow assembly. In other embodiments, the edge shoe is mounted using a quick release assembly. In some embodiments, the edge shoe is full length for use on a full blade, and in others is half-length for use on a left blade and right blade snow plow. When the snow plow assembly is lowered, an outer flat on the flattened C-channel is substantially parallel to the ground surface producing superior wear characteristics. Some embodiments include an additional wear plate secured to the outer flat and outer face of the flattened C-channel.
