A snow blower or snowblower is a machine for removing snow from an area where it is not wanted, such as a driveway, sidewalk, roadway, or runway. A typical snowblower has one or more augers that move the snow into an impeller which blows the snow to another location or into a truck to be hauled away.
Snowblowers range from the very small, capable of removing only several inches of light snow in a 18 to 20 inch path, to very large, capable of moving 10 foot wide swaths of heavy snow up to 6 feet deep. The former are powered by small electric motors. The latter are powered by large diesel engines of over 1000 horsepower.
