What are the Different Stages of a Snow Blower?

Snow blowers come in various widths and can either be powered by gas, or be electric.
Typically a snow blower will come in;

  • Single-stage
  • Two-stage
  • Three-stage

Single-stage and two-stage are more common however, three-stage is useful for larger areas or very deep snow. Knowing which snow blower to buy is important, so let’s go through what each one is good for to help you find which stage best suits your needs.

Single-stage

Single-stage snow blowers are used for light to moderate levels of snow. They are suitable for use on small driveways and pavements and will be able to clear the snow off your porch with ease. You can be expected to clear around 8 inches of snow with this compact snowblower.

How it works

The name single-stage derives from the snowblower scooping up the snow and spitting it out in a single motion. A single-stage snow blower uses a rubber auger, sucks in the snow, and discharges it through the chute.

Two-stage

If you are needing to clear a larger area, then two-stage is more ideal for the job. Two-stage snow blowers are useful for grassy areas or gravel driveways, however, there may be some snow left behind.

They will clear a larger width at a time than single-stage and can clear snow between 12 and 23 inches in depth. Two-stage snow blowers normally have engine-driven wheels which will help to prevent any faults or failures with the machine.

How it works

This snow blower is typically self-propelled and has forward and reverse functions. Combining the power of the two-stage snow blower with the auger and impeller, it clears snow faster. It chews up the ice and snow and spits it out through the chute.

Three-stage

Three-stage snow blowers can be up to 50% more powerful than two-stage and leave less snow behind, which makes for a cleaner driveway. For spaces larger than 18 meters, two-stage or three-stage are the most effective.

Three-stage snow blowers can handle sloped ground, either paved or unpaved, and will clear snow as deep as 23 inches. If you are dealing with a large amount of ice, a three-stage is particularly helpful.

How it works

In addition to the auger and the impeller, the three-stage also uses an accelerator. The accelerator spins at a 90-degree angle from the auger, working like a screw. Together they force the snow into the impeller where it gets discharged.

Conclusion

Which snowblower you should buy is dependent on your needs, and what you will use it for. For smaller jobs, a single-stage is sufficient whereas larger areas or deeper snow will require a two-stage or three-stage snowblower.
