Single-Stage Snow Blower vs Two-Stage

Single Stage vs Two-Stage Gas Snow Blowers

The Spruce / Michela Buttignol 

Snow blowers are a smart choice for removing snow from pathways, front walks, and driveways. Choosing between single-stage snow blowers vs. two-stage is important in terms of snow depth clearance, snow throw distance, types of terrain, and of course, price.

Find out about your single-stage snow blower vs. two-stage options.

Single-Stage Snow Blower vs Two-Stage

Snow blowers are either single-stage snow blowers or two-stage.

Single-stage snow blowers pick up and throw the snow using one part: the auger. Two-stage snow blowers pick up snow with the auger, but they add an impeller to throw the snow.

Snow Blower Auger

The snow blower auger is the large, spinning corkscrew-shaped part at the front of the blower responsible for pulling the snow from the ground.

  • Single-Stage Snow Blower: The auger both picks up and discharges the snow. The snow discharge distance is usually limited to about 36 inches. Because the auger touches the ground, it is covered in rubber to protect the surface. Augers are good at picking up snow but less effective at throwing snow.
  • Two-Stage Snow Blower: The auger only pulls up the snow from the ground. A separate component within the snow blower, the impeller, discharges the snow from the chute. This allows the snow blower to send the snow a greater distance—up to 60 inches—than with single-stage gas snow blowers. Because the auger does not touch the ground, it is all metal (not rubber-tipped, as with the single-stage models).

Gas vs. Electric Snow Blowers

Gas snow blowers are available in both single-stage and two-stage models. Electric snow blowers are only available in the single-stage option. Gas snow blowers are more powerful than electric models, plus they give you more mobility since you are not tied down by an extension cord.

Single-Stage Snow Blower
  • Auger gathers and throws snow

  • No fan impeller

  • Auger touches ground

  • 8-inch maximum snow depth

  • 36-inch throw distance

  • Good only for slight inclines

  • Soft rubber-tipped auger

  • Paved surfaces best

Two-Stage Snow Blower
  • Auger gathers snow only

  • Fan impeller throws snow

  • Auger does not touch ground

  • 24-inch maximum snow depth

  • 60-inch or more throw

  • Steeper inclines okay

  • All-metal auger

  • Paved, gravel, or dirt surfaces

Single-Stage Snow Blower

With single-stage models, the spinning auger cuts into the snow, gathers the snow, and discharges it from the chute.

Single-stage snowblowers never come in self-propelled form. But the spinning of the auger does slightly help to pull the snow blower forward as the auger contacts the surface.

Single-stage snow blowers are not recommended for regions prone to heavy snowfall or wet snow. They simply do not have enough power to move deep or wet snow. With a single-stage model, an 8-inch snowfall is around the maximum depth that the blower can handle.

Single-stage snow blowers are best for areas that only experience light or moderate snowfalls and for homes with paved small- or medium-sized two-car garages and driveways.

Two-Stage Snow Blower

With two-stage gas snow blowers, the auger that sucks up the snow does not contact the ground. This allows two-stage snow blowers to clear paved surfaces, plus crushed stone or gravel driveways.

Since the auger does not contact the ground, a thin layer of snow or ice will remain. This can be scraped or shoveled by hand or treated with ice melt.

Two-stage snow blowers can clear a wider surface than single-stage blowers can: often up to 30 inches in a single pass.

Engine-driven wheels or tracks propel two-stage gas snow blowers. The user only steers the machine and does not have to push it.

Low-End vs. High-End Snow Blowers

Lower-End Snow Blower
  • Narrow clearing capacity—21 inches

  • Sometimes start with pull cord

  • Few or no extra features

Higher-End Snow Blower
  • Broad capacity—up to 30 inches

  • Always have electric starts

  • Features like headlights, heated grips, improved steering

Single-Stage Snow Blower

Lower-end single-stage snow blowers tend to have narrow clearing paths—around 21 inches wide. Some of the lower-cost single-stage models may require you to pull a cord (like some lawnmowers) to start the machine.

Higher-end single-stage snow blowers will have wider tracks, electric starters, and extra features such as headlights and semi-pneumatic tires.

Two-Stage Snow Blower

Many lower-end two-stage snow blowers are essentially the same as single-stage models except for one difference: the separately powered snow thrower.

As two-stage models reach the upper end of quality, they have clearing widths ranging from 30 to 40 inches and a greater snow-throwing distance. All upper-end two-stage models have electric starts.

Many of these premium snow blowers have features such as dual-grip steering, heated grips, dash-mounted chute rotation, low-temperature starting capacities as low as 20 degrees below zero, and tight turning ratios.

Cost

Gas-powered snow blowers begin at around $500 for single-stage wheeled models and peak at around $4,500 for two-stage track-mounted models.

A reasonable middle price point for snow blowers ranges from $800 to $1,200. The lower end of this price span brings you 24-inch to 30-inch dual-stage snow blowers with electric starters.

The upper end gives you helpful extras like LED headlights, heated grips, and a greater number of gears.
