Parts of a Snow Blower

A snow blower consists of several different parts, which work together to help you clear snow from your property. A spinning auger, powered by a motor pushes snow into a discharge chute. The power of the engine shoots out the snow to the side and out of the way.

Here is a look at the different parts of a snow blower.

Motor

The motor is the powerhouse of a snow blower. Depending on the make and model of the snow blower, the size of the motor can be different. To understand how a snow blower works, you need to know that different kinds of motors affect a snow blower’s capabilities. A gas engine offers more power, but is powered by gasoline which is less convenient than the electric power a corded or cordless electric snow blower uses. Electric motors are less powerful than gas motors, but are less costly to buy and maintain.

Auger

The next step in understanding how a snow blower works is to know about the auger assembly. This is a system that consists of blades that rotate because of the power provided by the snow blower’s motor. The snow in the snow blower is collected by the auger assembly area and the spinning blades expel the collected snow through the chute.

Inlet

There is a reason why a snow blower’s auger is able to collect and remove snow through its chute. The inlet is that part of the snow blower in the front where the snow enters the equipment. The width of the inlet determines how much snow the snow blower can take in and throw out through the chute. It is a vital part of how a snow blower works and how much snow it can clear out in one pass.

Chute

A snow blower’s motor provides the power, the inlet gets the snow into the machine and the auger assembly expels the snow out. All of the accumulated snow is pushed out through the chute. The chute faces to one or other side of the snow blower in normal operation, so it blows the snow away from your driveway, deck or sidewalk. You can change the direction the chute faces, and often adjust the distance the snow will be thrown, so you don’t end up throwing the snow somewhere you’ll have to clear it again.

Impeller

The impeller is found in two-stage and three-stage snow blowers. In multi-stage snow blowers, the auger does the job of accumulating the snow. It then directs the snow towards the impeller. The impeller is a high speed set of blades, which is solely responsible for expelling the snow through the chute. By separating the tasks of collecting & expelling the snow, each task can be done more efficiently.

Conclusion

While there are subtle differences in different types of snow blowers, they all use the same general concept – the snow goes into the snow blower through the inlet, the auger collects the snow and the snow goes out the chute.
