A snow blower is a mechanical device that clears snow from a surface by collecting it and forcibly throwing it to another location. It was invented in Quebec by Arthur Sicard in 1925. Snow blowers typically use an auger — a corkscrew-shaped blade made of metal, rubber or plastic — to collect and then distribute snow. Some snow blowers, known as two-stage snow blowers, also feature a collecting chamber and impeller to make it easier to clear large deposits of snow. These powerful machines help keep streets, sidewalks and driveways clear during winter.
