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.

An impeller assembly for a snowthrower includes a flexible impeller configured to rotate about an axis, wherein the flexible impeller extends radially from the axis to an impeller radial distance, and a cutting implement extending radially from the axis to a cutting implement radial distance less than the impeller radial distance, wherein the cutting implement is spaced apart from and does not contact the flexible impeller.

An impeller assembly for a snowthrower includes a driven shaft configured to rotate about an axis, a flexible impeller paddle coupled to the driven shaft for rotation about the axis, and a rigid cutting implement coupled to the driven shaft for rotation about the axis. The flexible impeller paddle is configured to clear snow from a surface to be cleared. The flexible impeller paddle extends radially from the axis to a paddle radial distance. The rigid cutting implement is configured to break up snow or ice on the surface to be cleared. The rigid cutting implement extends radially from the axis to a cutting implement radial distance less than the paddle radial distance.
