Abstract: A snow thrower impeller assembly (24) defines a mounting slot (84) for a wiper (70) in an embodiment. 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. Improving the efficiency of a snow thrower is described in one or more methods.

Abstract: A low-energy blade system having a quick-change attachment for a lawn maintenance tool is provided. The low-energy blade system requires a reduced amount of energy to rotate the blade system. The blade system includes a shell, a mounting plate attached to the shell, a plurality of quick-attach mechanisms, and a separate cutting blade attachable to each of the quick-attach mechanisms. Each quick-attach mechanism allows a cutting blade to be attached to the mounting plate without the need for external tools, such as screwdriver, wrench, ratchet, or the like.
