Abstract: Suspension systems and grounds maintenance vehicles incorporating the same are disclosed. The suspension system may include biasing elements or springs that may be adjusted to vary the preload and thus change the spring and dampening characteristics of the suspension system. In some embodiments, the system may include an adjustment mechanism that permits simultaneous adjustment of two springs via a single action. In other embodiments, features adapted to assist an operator with mounting/dismounting the vehicle are disclosed.

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.

Abstract: A snowthrower having a rotor housing with first and second sidewalls and a rotor extending between the sidewalls. As the rotor wears, it may be repositionable, relative to a ground surface and to the rotor housing to maintain snowthrower performance. In some embodiments, end portions of the rotor may connect to the sidewalls via an adjustable coupler.
