| Single-stage electric snow blowers are best suited for townhouses and homes with short, level driveways and walks. They are built without wheels and use the auger that collects and throws the snow to propel the blower. Electric snow blowers are most effective in four inches or less snow and can clear a path 11-18 inches wide. The single-stage electric motor allows for continual use without having to refuel or conduct engine maintenance, but it lacks the power needed to clear inclined surfaces. The electric engine also limits the user’s mobility to the length of its power cord. Electric powered blowers are the quietest, cleanest, and lightest snow blowers on the market and are usually the least expensive. |

| Single-stage gas powered snow blowers are slightly larger and more powerful than their electric cousins. These snow blowers can handle up to eight inches of snow and most models can clear a path 20-22 inches wide. The auger can propel the machine up small inclines, but will pull to the side when the incline is too steep. Since the engine is gas powered, these machines are free to work anywhere and are still relatively light and maneuverable. Most single-stage gas blowers have two-cycle engines that require the user to manually mix the gasoline with oil. While being the perfect machine for clearing midsized paved driveways, the auger is known for picking up gravel and loose stones on unpaved surfaces. |

| Like their names suggests, two-stage gas powered snow blowers use two elements to collect and throw the snow. Two-stage blowers first collect the snow using an auger, like other snow blowers. As the auger moves the snow towards the chute, a fast-spinning impeller forcefully throws the snow out of the chute, allowing the machine to efficiently handle more snow than single-stage blowers. These snow blowers can clear paths 28-30 inches wide and can deal with snow more than eight inches deep. These machines are much larger and more powerful than their counterparts and use the engine to propel its wheels. This keeps the auger from touching the ground, allowing the blower to work on both paved and unpaved surfaces. With power comes size, and these snow blowers can take up a lot of room in the garage.
Industrial-Grade Machines
For clearing enormous surfaces like airport runways, industrial-grade snow blowers are attached to trucks and front-end loaders. They utilize the same technology of two-stage blowers, an auger and an impeller, but on a larger scale. These units are general diesel-powered and can move up to 5000 tons of snow every hour. |
