  • Patent number: 7997406
    Abstract: A conveyor apparatus includes a tail portion connected to a head portion such that the head portion is moveable relative to the tail portion from a first position to a second position located lower than the first position. It should be appreciated that such movement of the head portion can permit the drop height of the conveyor apparatus to be adjusted. At least one frame portion is moveably positioned between the tail portion and the head portion. A stacker is also provided that includes the conveyor apparatus.
    Type: Grant

  • Patent number: 7748203
    Abstract: An implement for negotiating sloped hillsides having a front carriage with a rigid axle that stays oriented to the slope of the ground being traversed. The front axle and drive assembly has two opposing tilt connections which allow hydraulic or other operators on the opposite side of the implement to extend and tilt the implement body to maintain a level condition. This arrangement keeps the center of gravity lower and positions the points of load application to the axle assembly nearer the ends of the axle and adjacent to the wheels and tires or other ground contacting drive. The operator on one side is contracted when the opposing operator is to be extended. One operator is used to tilt in one direction and the opposing tilt operator is used to tilt in the opposite direction.

  • Patent number: 4750751
    Abstract: In the forward undercarriage of a self-propelled hillside combine, all components for support and control of the transverse equalizing or balance beam, are below the floor level of a forward portion of the combine's separator body. In a compact structure which maintains good access to the separator concave and stone trap, and also to the hydraulic cylinders used to control the balance beam, the leveling cylinders diverge widely from a center pivot assembly so as to provide smooth action in control of the balance beam and also to minimize bending moments in the balance beam.
