Dependent claims

A snow thrower, comprising:

a first drive shaft that rotates about a first axis;
an auger comprising auger blades mounted to the first drive shaft;
a second drive shaft that rotates about a second axis;
an impeller comprising a impeller base mounted to the second drive shaft and impeller blades mounted to the impeller base;
a wheel assembly that supports the snow thrower upon a surface;
