Zusammenfassung:	A hand operated snow thrower has an impeller with blade mounts that allow the blades to be easily removed, yet effectively retained with the blade mount. The impeller includes a rigid rotor that is rotatably driven by the snow thrower. The rotor has three blade mounts, each blade mount having a blade supporting surface. The blade supporting surface has an inner edge and an outer edge. A retainer extends over the inner edge of the supporting surface to define a channel. A slot extends from the supporting surface rearwardly into the rotor. The flexible blade that is mounted to the impeller has a flange that is received within the slot. The blade has an inner edge that is received within the channel.
