Abstract: A manual electrically powered snow throwing device has features that allow it to be used either in a shovel mode or in a pushing and pulling mode. The device has an upper handgrip with forward and rearward handgrip portions. The forward handgrip portion is located on the same axis as that of the handle. The rearward handgrip portion extends downwardly from the forward handgrip portion. The triggers are mounted to both forward and rearward handgrip portions. These triggers are connected in parallel, so that each will independently control the motor. The forward handgrip portion is used for a shovelling motion, while the rearward handgrip portion is used for pushing and pulling motion.

Abstract: 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.
