  • Publication number: 20190200525
    Abstract: A crop feeding apparatus having a roller through which the fingers are extended and retracted, has fingers that are formed with tubular finger bodies extending between an inner end configured to be mounted on a finger drive arrangement of the crop feeding apparatus and an outer end of the finger body configured to protrude from the outer peripheral wall of the roller. A breakaway region is formed in the finger body by diametrically opposed slots which are circumferentially elongated to define a shear plane perpendicular to the long axis of the finger body. A slot axis extending between opposing ends of each slot is parallel to the axis of the crop feeding apparatus. The finger body is also hardened by heat treating, and by applying a wear resistant coating over the heat treated body.

  • Patent number: 9706707
    Abstract: In a swather a support arm is attached to the header to carry the heavy hydraulic hoses which are connected to the tractor for supplying the drive fluid to the hydraulic system of the header. The support arm is articulated so as to accommodate the up-and-down and twisting movement of the header relative to the tractor during harvesting action and this supported to prevent collapse when the hoses are disconnected from the tractor manifold. The support arm is attached at the rear to the tractor preferably at the wheel strut by a releasable ball joint coupling. From the coupling at the wheel strut, there is a free portion of the hydraulic hoses which extends to the manifold at the tractor where the ends of the hoses are attached to manually graspable handle portions which can be lifted away and the attached to a bracket on the support arm.

  • Patent number: 9392747
    Abstract: A crop feeding roller for a header includes a plurality of finger units within the roller each having a pair of fingers projecting outwardly for engaging crop outside the peripheral wall of the roller. The peripheral wall has opposed finger guide holes associated with the pair of fingers. Each finger unit including an inner member carrying the fingers and containing an elongate guide slot transverse to the axis of the roller and a stationary guide member within the guide slot at a position within the roller arranged to cause the inner member with the fingers of each of the finger units to reciprocate during the rotation of the roller. The guide slot is shaped with at least one curved lobe to one side of a transverse center section so that the slot can be S-shaped or C-shaped to improve the dwell time and swept area obtained by the finger movement.

  • Patent number: 9258941
    Abstract: A crop header has generally horizontal flail disks mounted for driven rotation about generally upright axes of a cutter bar. A tilting system is provided for tilting the cutter bar about an axis transverse to the machine so as to tilt the cutting plane from a generally horizontal position forwardly and rearwardly. A sensor is provided which is responsive to upward and downward floating movement of the cutter bar relative to the support frame and is arranged to analyze changes in the signal to determine times when the cutter bar is moving upwardly when the cutter bar is tilted rearwardly, times when the cutter bar is moving downwardly when the cutter bar is tilted forwardly and times when the cutter bar is remaining at a constant height.

  • Patent number: 8863484
    Abstract: A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. It can be driven cab forward in a working mode with a header on the forward end. It is rotated to engine forward in the transport position for more stable higher speed travel. There is provided a float module with adjustable and calibrated springs on the header which allows the header to float relative to the lift system on the tractor. The float force is adjusted by raising and lowering the lift system in dependence on an angle measurement of the lift position. The lift system includes a lift cylinder and tilt cylinder controlled to change cutter angle while maintaining a sight line to the cutter bar for the operator.

  • Patent number: 7497069
    Abstract: A crop harvesting header includes a sickle knife driven by a first hydraulic motor and a crop transfer system including three conveying drapers which is driven by at least one second hydraulic motor. A mechanical drive input from the combine harvester drives a first pressure regulated piston pump generating flow for the first motor and a second gear pump for the second motor. When the drive input is driven in the reverse direction, hydraulic fluid is supplied from the second pump in the reverse direction for driving the second motor in the reverse direction. As the first pump does not pump in the reverse direction the hydraulic control circuit is arranged such that, when the second pump is driven by the drive input in the reverse direction, hydraulic fluid is supplied from the second pump to the first motor for driving the first motor in the reverse direction.
