Abstract
An impeller assembly for a snowthrower includes a driven shaft configured to rotate about an axis, a flexible impeller configured to rotate about the axis and extending horizontally across substantially a complete width of the impeller assembly parallel to the axis, and a rigid cutting implement. The flexible impeller extends radially from the driven shaft to an impeller radial distance. The rigid cutting implement extends radially from the driven shaft to a cutting implement radial distance less than the impeller radial distance, wherein the rigid cutting implement is spaced apart from and does not contact the flexible impeller.
