Single-Stage vs Two-Stage Snow Blower: Which One Do You Need?

How a single-stage snow blower works

A single-stage machine uses one spinning auger that scoops snow and throws it out of the chute in one motion. The auger touches the ground, which helps it clean down to the pavement and pull the machine forward.

Single-stage blowers are lighter, cheaper and easier to store. They suit paved driveways and walkways that usually get light to moderate snowfall.

How a two-stage snow blower works

A two-stage machine adds a fast impeller behind the auger. The auger breaks up and feeds the snow, then the impeller throws it much farther. The auger sits slightly above the ground, so two-stage machines can be used on gravel.

They handle deep, wet and packed snow — including the heavy pile the street plough leaves at the end of the driveway.

Quick decision checklist

Choose the type that matches most of your storms, not the single worst one.

• Regular snowfall under about 8 inches and a paved surface: single-stage.
• Frequent deep or wet snow, long driveways or a gravel surface: two-stage.
• Small storage space or a tight budget: battery or electric single-stage.
• Steep slopes: a self-propelled two-stage machine is much easier to control.
