What is the difference between a Single-Stage vs Two-Stage Snow Blower?
- A Single-Stage Snow Blower is a relatively small, lightweight snow clearing machine.
- A Two-Stage Snow Blower, on the other hand, uses a heavy-duty serrated auger to pull snow in and break up chunks of ice (stage one). Then, an impeller launches the snow out of the top discharge chute (stage two).
Single-Stage Snow Blowers are ideal for smaller jobs like sidewalks, walkways and short driveways. They are lighter, compact and easier to handle than two-stage models, but they are only suitable if you get 8 inches or less of snow.
A Two-Stage Snow Blower has power assisted wheels which helps when clearing on slopes and large areas.
On a single-stage snow blower, an auger (the blades you see in front of the blower) directs the snow straight through a discharge chute. The auger makes contact with the surface you are clearing so it should only be used on a paved surface.
On two-stage Snow Throwers the auger collects the snow and a fan then discharges the snow through a chute which throws the snow faster and farther away. The auger on a two-stage thrower does not contact the surface so it can be used over gravel or dirt.
There’s also a third type of snow blower, too: A Three-Stage Blower is like a turbo-charged two-stage. It operates the same way but has an accelerator that moves much faster than an auger and is used for clearing heavy/wet snow quickly.
