A snowblower is a machine used for removing snow from an area where it is not wanted, such as a driveway, sidewalk, roadway, or runway. The snowblower uses electric power or a gasoline or diesel engine to throw snow to another location or into a truck to be hauled away. This is in contrast with the action of snow plows, which push snow to the front or side (shovels can be similarly used).
Arthur Sicard is credited as being the inventor of the snowblower. In 1925 Sicard created a vehicle which could remove snow from the roadways of Montreal.Snow blowers can range from the very small, and 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. Snowblowers can generally be divided into two classes: single stage snowblowers, and two stage snowblowers.
Single stage snowblowers use a single high-speed impeller to both move the snow into the machine and force it out the discharge chute. The impeller is usually in the form of two or more curved plastic paddles that move snow towards the centerline of the machine where the discharge chute is located. By comparison, two stage snow blowers have one or more low-speed metal augers that break up the snow and move it into a separate high-speed impeller.
