In a snow blower that is a single stage the auger is doing both tasks of bringing in the snow and blowing it out the chute. A two stage has a separate impeller that blows the snow out of the chute.
Three-stage snow blowers are gas models capable of handling more snow in less time. Operationally similar to the two-stage model, the three-stage blower features an accelerator that moves 10 times faster than the augers to clear more heavy snow quicker than a two-stage model.
