The Difference between a Single-Stage Snowblower and a Dual-Stage Snowblower



Understanding the difference between a single-stage snowblower and a dual-stage snowblower helps you to determine which snowblower type would be better suited to your needs. We’ve put together some quick facts about how each type of snowblower works.

Single-Stage Snowblower

A single-stage snowblower removes snow with one motion, using an impeller or auger. The auger is usually formed from two or more curved plastic paddles.  These paddles pull the snow into the unit and then throw it out through the chute.

The snowblower sits low to the ground and removes snow down to the pavement. A single-stage snowblower is lightweight and easy to maneuver.  It is best for clearing paved, moderate-sized driveways with snowfall depths of 10 to 12 inches.

Dual-Stage Snowblower

A dual-stage snowblower removes snow with two components; a serrated-edge auger blade and a high-speed impeller. The auger cuts through the snow and feeds it to the impeller, which propels the snow away through the chute. 

A dual-stage snowblower is slightly raised to allow for use on gravel driveways; as a result, it leaves a thin layer of snow behind. The dual-stage snowblower is larger than a single-stage, making it ideal for deeper snow and larger driveways. It is also self-propelled, making it perfect for use on steep areas.
