Depending on whether it is a single-stage or two-stage, the snow blower consists of the following components.
- Auger
This is a spiral metal, corkscrew-shaped, rotating blade at the front of the snow blower that scoops up the snow and transfers it to the center of the machine.
- In a single-stage machine it is also responsible for discharging the snow in a single motion.
- The auger of a two-stage snow blower is devoted exclusively to collecting the snow and transferring it to the center. An impeller discharges the snow.
- Impeller (two-stage snow blower)
The impeller (or turbine) is the second part of a dual-stage snow blower, just behind the auger. It grabs the snow and propels it up the chute.
- Chute
The chute is a chimney, behind the auger housing. It directs the snow outside to where you want it to go.
The charts below give you a general idea as to the capabilities of a single-stage versus a two-stage snow blower.
