228:, jamming it and stalling the motor. This is complicated by the fact that the auger could deform before applying enough resistance to the motor to turn it off. If the jam is cleared by hand, it is possible for the auger to return to its natural shape suddenly and with great force, possibly injuring the operator. Snow blowers are a leading cause of traumatic hand and finger amputations. The correct procedure is to turn off the engine, disengage the clutch and then clear the jam with a broom handle or other long object. In an effort to improve safety, many manufacturers now include a plastic tool to be used to clear jams, often mounted directly to the snow blower.

blowers unsuitable for use on unpaved surfaces. On a two-stage snow blower, the auger pulls snow into the machine and feeds it into a high-speed impeller, which in turn directs it out of a discharge chute. Two-stage snow blowers can generally handle deeper snow depths than single-stage ones, and because their augers don't touch the ground, they can be used on unpaved surfaces.

Snow blowers can generally be divided into two classes: single-stage and two-stage. On a single-stage snow blower, the auger (the paddle mechanism visible from the front) pulls snow into the machine and directs it out of a discharge chute. The auger contacts the ground, making single-stage snow

The jet engine both melts and blows the snow, clearing the tracks faster than other methods. While offering considerably greater power in a relatively lightweight machine, this method is much more expensive than traditional snow removing methods. In

Snow blowers range from the very small, capable of removing only a few inches (a few more cm) of light snow in an 18 to 20 in (457 to 508 mm) path, to the very large, mounted onto heavy-duty
