Abstract
A snow thrower comprises an impeller 12 which has forward facing blades which extend a short distance inward from the periphery of the impeller. The impeller blades are substantially rigid during operation, and the impeller cooperates with two side walls and a continuous rear wall which form the active impeller housing 14. The continuous rear wall has a first portion whose cross section is a circular arc and generally follows the periphery of the impeller mounted within it, and a second portion which extends forward and upward to define a substantially planar snow guiding surface which, in normal operation, guides the snow forwardly and upwardly as it leaves the area of interaction with the impeller. <IMAGE>
