A heavy duty walk-behind two-stage snow blower.

A snow blower, snowblower, or snow thrower is a machine for removing snow from an area where it is not wanted, such as a driveway, sidewalk, roadway, or runway. It can use either 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).

Snow blowers range from the very small, capable of removing only several inches (a few cm) of light snow in an 18 to 20 inch (45 to 50 cm) path, to very large, mounted onto heavy duty winter service vehicles and capable of moving 10 foot (3 m) wide swaths of heavy snow up to 6 feet (2 m) deep. Snow blowers can generally be divided into two classes: single stage and two stage. A winter service vehicle clearing roads near Toronto, Ontario, Canada. ...

Single stage snow throwers

Single stage rotary snowblower of the Furka-Oberalp-Bahn in Disentis

Single stage snow throwers 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. Single stage snow throwers usually are light duty machines. Small electric machines can actually be picked up to chew away deep snow banks a layer at a time.

Two stage snow blowers

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 (sometimes called the fan). The impeller 'blows' the snow out the discharge chute with considerable force. All but the lightest-duty snow throwers are typically two-stage machines.

Two stage snow blowers range in power from a few horsepower to very large machines powered by diesel engines of over 1000 horsepower(750 kW). The large machines are used for clearing roadways and airport runways. These are capable of removing large amounts of snow quickly. Some municipalities use larger snowblowers to clear snow from streets after a snowfall, often by blowing the snow into trucks which haul it away.

Two stage machines for home use are usually self-propelled, using either large wheels equipped with tire chains or, in some cases, tracks. These are usually single-purpose machines, though some are detachable front ends that can be replaced with other implements, such as a rotary tiller. Snow chains, or tire chains, are chains which are affixed to the wheels of vehicles to provide superior traction when driving through snow and ice. ... A Rotary tiller is a motorised cultivator that works the soil by means of rotating blades. ...


The auger drive is usually equipped with a shear pin. If a major jam occurs, this pin will break rather than allowing the internal drive gears to be damaged. The pin must then be replaced by the user before operation can resume. A shear pin is the mechanical analogue of an electric fuse. ...


Safety issues

One problem with the design of the snowblower is that snow can build up in the auger, jamming it and stalling the motor. This is complicated by the fact that the auger may twist before applying enough resistance to the motor to stop it. If the jam is cleared with a hand, it is possible for the auger to return to its natural shape suddenly and with great force, possibly injuring the user; snowblowers are a leading cause of traumatic finger amputations. [1] The correct procedure is to stop the engine, disengage the clutch and then clear the jam with a broom handle or other long object.

Most modern machines mitigate this problem by including a safety system known as the "Dead man's switch" (which may be electrical as implied or mechanical in design, such as a lever), to prevent the mechanism from rotating when the operator is not at the controls. In some jurisdictions, this is a mandatory requirement. A dead mans switch (for other names, see Alternative names), as its name suggests, is a device intended to stop a machine in case the human operator becomes incapacitated, and is a form of fail-safe. ...

History

Arthur Sicard (December 17, 1876 - September 13, 1946) is credited as the inventor of the snow blower. Arthur Sicard lived on a farm when he was a boy, and used to sell milk. Finding that snowfall would prevent his selling of milk, he dreamed up an idea for a machine that would blow snow and clear up roadways. In 1925 Sicard completed his first prototype, based on a concept he described in 1894.[2] He founded Sicard Industries in Sainte-Thérèse, Quebec and by 1927 his vehicles were in use removing snow from the roadways of the town of Outremont, now a borough of Montreal. His company is now a division of SMI-Snowblast, Inc. of Watertown, New York, USA, as well as a Canadian operation, Sicard SSI Group, Inc. in Knowlton, Quebec.[3] December 17 is the 351st day of the year (352nd in leap years) in the Gregorian calendar. ...

Plow attachment for snow blower - Patent 4023287 (2679 words)
For snow of a wet consistency, there is a tendency for the snow to stick to the sides of and thus clog the discharge chute of a snow blower thus rendering the apparatus useless.
Thus, it is quite common for the owner of a snow blower to nevertheless resort to partial shoveling of the area to be cleared due to the lack of a suitable direction in which the snow blower discharge chute may be aimed.
Snow blower 10 is of the type behind which the operator will walk and includes a shielded rotary blade 12 which delivers snow to a discharge chute 14 in the known manner.
Snow blower deflector shield - Patent 4190973 (2274 words)
A snow blower has a framework with a handle, a laterally adjustable vane shifter plate, a series of shiftable upright vanes for delivering streams of snow forwardly and laterally.
In the snow blower of claim 1, the securing of said vane cap plate to said vane shifter plate including an elongated spacer between said plates, and a series of spaced fasteners extending between said plates and spacer.
The present snow deflector shield is automatically adjusted from side to side as the operator adjusts the vanes 33 through the action of the shifter plate 31 and its conventional control handle 37-39.
