A snow blower works in two stages; like a snow thrower, it has a rotating auger to scoop up snow, but the snow is then fed into an impeller, which is akin to a powerful fan that launches the snow up to 35 feet away, or farther. At the even more powerful end of the Snow Blower spectrum are three-stage blowers that feature accelerators that chew through hard-packed snow and even ice, crushing it and feeding it into a mighty impeller that can launch snow up to 50 feet away.
