  • Patent number: 6185920
    Abstract: A self-propelled utility tractor having articulated steering, a standing operator, a turning radius near the rear wheel on the inside of a full turn, the radius of turn being not substantially longer than the wheel base, independent rear wheel brakes to assist in tight turns, a steering wheel for operating a steering linkage, an engine and transmission, centrally mounted with the engine below the transmission transmitting power by a jack shaft so the out put shaft of the engine extends down to power an attachment. Where the attachment is a mower deck, a rear discharge chute on the tractor deflects the clippings uniformly across the rear to avoid wind rowing. Flexible elements rotate above the mower blade to provide additional mulching and turbulent air flow and self-cleaning of the underside of the deck.

  • Patent number: 6112612
    Abstract: A single lever hand control for multiple functions having two distinct axes of movement. In the case of a stand-up, battery powered lift truck having a mast, a carriage with forks raised and lowered on the mast, and the forks side shifted on the carriage, which also can be tilted from vertical, forward or back, the operator stands facing to the side with reference to the direction of travel of the truck. Movement of the control lever right to left from a neutral position relative to the direction the operator is facing controls the forward or reverse direction and the speed of the truck. The mast and carriage operations are controlled by the lever being pushed or pulled by the operator transversely to the direction of travel. The force required to displace the lever in one direction is less than that required in the other consistent with the large muscle groups employed to overcome the respective forces.
