The snow thrower includes a housing having a transversely extending discharge chute and an impeller rotatably mounted in the housing below the discharge chute and carrying a plurality of elongated, axially extending blades having a length substantially coextensive with the width of the discharge chute and a radially outwarding extending propelling section. The propelling section is in the form of a continuous series of corrugations with alternating peaks or ridges and valleys or furrows defining a plurality of generally V-shaped cups or pockets into which snow is compacted and from which snow is propelled upwardly toward the discharge chute during rotation of the impeller.
