    Abstract: A self-propelled, single-stage snowthrower wherein, in one embodiment, drive members on each side of the snowthrower provide variable speed propulsion. A transmission that delivers power to the drive members may be adapted to de-clutch one of the two drive wheels when the ground speed of that wheel exceeds the driving speed of the transmission. In other embodiments, the snowthrower includes a rotor having a snow ejection surface forming a negative rake angle. Yet other embodiments include a chute rotation control mechanism that permits manual discharge chute rotation via one-handed input.

    Abstract: A housing for a snowthrower including an auger housing and an impeller housing. The auger housing may include a front portion and a rear portion protruding from a rear wall of the front portion. The impeller housing may be coupled to the auger housing at a rear-facing opening of the rear portion. At least a portion of the rear portion and the impeller housing form a bypass passage adapted to return snow that bypasses a discharge outlet. The snowthrower may also include an auger that includes a helical flyte adapted to collect snow. The helical flyte may include a first helical portion and a second helical portion, wherein the first helical portion is overlapping and coupled to the second helical portion.
