Abstract
The rotary snow blower plow with a plow worm (18) which delivers the snow and a fan blower (19) which throws the delivered snow. The fan blower (19) is located on a line with the plow worm (18). The fan blower (19) and the plow worm (18) can be mounted on a common shaft (23) so that they rotate with the same angular speed. The rotary snow blower plow is characterized by high efficiency since the flow of snow need not be deflected by 90 degrees. It is especially suited for clearing of side walls and preparation of half pipe courses.
