    IPC: E01H5/04

    Abstract: Provided is a snow thrower impeller assembly (24) that defines a mounting slot (84) for a wiper (70). The wiper includes a wiper portion (86) that slides into the mounting slot to mount the wiper to the impeller (54). The wiper contacts an interior wall (56) of an associated impeller housing during rotational operation of the impeller in order to limit a gap (74) between an impeller blade (66) and the interior wall. The wiper can move radially inward and outward to remain in contact with the interior wall without input from the operator. Another embodiment of the impeller assembly includes impeller blades with a first portion (116) and a second portion (118). The second portion extends at a non-zero angle from the first blade portion of the impeller blade. Methods of improving the efficiency of the snow thrower are also provided.

    Abstract: A walk-behind working tool having a frame, a power source, and a handle attached to the frame is provided. The working tool includes at least one axle operatively connected to the frame and a pair of wheel assemblies connected to the axle. The wheel assemblies include a hub, a rim, a tire, and a flexible vibration dampening assembly that operatively connects the hub and rim, wherein the dampening assembly is configured to reduce the vibration transferred between the rim and hub and through the handle to the operator. The dampening assembly includes a plurality of elastic elements having a spring constant for smoothing out movement of the frame when the working tool is guided over rough or uneven ground.
