For our snow loving friends, who hate blowing snow out of the drive, just think about the railroads. There are several you tube videos on railroads efforts to remove snow from trackage. Some use wedge plows, and others use rotary plow. The rotary plows can handle drifts over ten feet high, by ten feet wide in one pass. The forward motion is furnished by a couple 5000 HP diesels in one video. Ironically in this modern age, everything on the rotary, except the rotary, is steam operated. With it being steam operated, you don't have to worry about snow build up.
