1. An impeller for a snowblowing apparatus, the impeller being designed to rotate about a rotation axis thereof, the impeller comprising:
a front axial region thereof, the front axial region being configured to receive snow therein in an impeller's eye; a rear axial region thereof; a periphery thereof; a hub, generally located between the front axial region and the rear axial region, adapted to rotate about the rotation axis of the impeller; a plurality of axial vanes generally radially extending from the periphery of the impeller toward the rotation axis, the plurality of vanes including a portion configured to propel snow disposed between the front axial region and the rear axial region, the plurality of vanes including a void area around the rotation axis toward the front axial region for receiving snow in the impeller's eye, the plurality of vanes including a respective snow-engaging portion secured thereon, the snow-engaging portions being generally located toward the front axial region of the vanes and respectively angularly aligned and secured adjacent to the plurality of vanes, wherein the snow engaging portions are orthogonally positioned in respect to the rotation axis and are extending from the periphery further toward the rotation axis over the impeller's eye, the snow engaging portions including an angle of attack toward the front axial region for engaging snow when the impeller is rotating about the rotation axis. |
