ABSTRACT:
A portable rotary snow blower shovel which is lightweight and maneuverable is disclosed. The device uses the drive mechanism from a rotary string trimmer. In place of the string and string guard, the snow blower utilizes an impeller and a substantially cylindrical enclosure. The enclosure includes a cutout opening in a lower portion of the periphery to allow snow to enter. Adjacent the opening is a flat plate which is secured to the inside of the enclosure at an angle in order to direct snow upward toward the impeller. The impeller, which is oriented substantially parallel to the surface being cleared, is circular in shape and has radially projecting blades attached to the upper and lower surfaces thereof. Once the snow is directed upward by the angled flat plate, the blades of the impeller, which are rotating at a high speed, force the snow out an exit conduit adjacent the top of the cylindrical enclosure by centrifugal force. The exit conduit directs the snow upward and away from the path being cleared.
