A single-stage blower uses a rotating, rubber tipped auger to pick up snow from driveways and sidewalks and throw it either forward or through a chute in a single motion.
Do not use a single-stage blower on gravel driveways, as the blower could pick up and sling stones.
A two-stage blower can be used on gravel and is best for large areas or deep snow. This blower operates by first picking up snow with a slow turning metal auger, then slinging it out a chute from a fast-spinning impeller. These types are usually self-propelled.
Desirable features include easy chute and deflector adjustment, headlights and folding handles for easy storage.
Choose the model based on the typical amount of snow in your area. For areas with 12” to 18” of snow, recommend a two-stage model with 7 to 9 hp. For areas with moderate accumulations, recommend a 5.5 to 8 hp machine. For a smooth surfaces and light snowfall, recommend a single-stage blower.
Clearing paths for two-stage blowers range from 21” to 31”.
