  • Crop Harvesting Machine with Calibration of the Header Float Springs
    Publication number: 20130305674
    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.

  • Sickle Guard Shape for Use in a Sickle Cutter System with Increased Ground Speed
    Publication number: 20130305681
    Abstract: In a sickle cutting system, it has been found that a significant increase in ground speed while maintaining an acceptable level of cutting efficiency as measured by the average stubble length can be obtained by a combination of one or more of the features where the cutting stroke is reduced from the conventional length of 3.0 inches to a value of the order of 2.0 inches; the length of the cutting edge of each knife blade is increased to a length greater than 2.2 inches; the width at the rear of the ledger surface of each guard is increased to greater than 1.0 inches; and the front edge of the blade is formed with an apex to shed crop material to one or other side of the apex.

  • Swather tractor with frame suspension
    Patent number: 8408567
    Abstract: A swather tractor has a frame defined by a main tractor frame carrying the cab, engine and drive system, rear axle with castor wheels and a transverse front frame assembly mounted at a front of the main frame. The front rigid frame assembly carries the header and comprises a cross member and a pair of upstanding legs each carrying a front ground wheel hydraulically driven so that steering is controlled by the rate of forward movement of the front wheels. In order to provide improved suspension, the main frame is connected to the front frame assembly by a coupling which allows up and down suspension movement of the main frame relative to the front frame assembly.

  • Crop harvesting header with rotary disks and impellers for transferring the crop inwardly to a discharge opening
    Patent number: 8341927
    Abstract: A crop header has generally horizontal flail disks mounted for driven rotation about generally upright axes. A pair of conditioner rolls is mounted in a discharge opening and a transfer roller is mounted behind the disks and in front of the nip. At each end, two disks are mounted outwardly of the discharge opening each rotating so that its blade moves inwardly and each carries an impeller to carry the crop inwardly. A third disk is arranged so that a line forward of the end of the discharge opening intersects the third disk inward of the axis of the third disk. The third disk rotates so that its blade moves outwardly so that the crop tends to pass between the second and third disks. A pair of impellers are mounted behind the second disk and move inwardly to carry the cut crop to the discharge opening.

  • Swather with automatic reel control
    Patent number: 8291684
    Abstract: In a swather formed by a tractor and attached heeder for cutting standing crop to form a swath, reel speed and optionally draper speed are controlled relative to ground speed by a control system including a manually operable input and display available to the operator. The control system can be used in an automatic mode to set an index value for an actual difference in reel speed relative to ground speed and to vary reel speed accordingly. In this mode a manually operable control varies the index. The control system can be switched by the operator to manual in which case the same control varies the actual reel speed. Minimum reel speed can be set by the same control and when operative the automatic system does not allow reel speed to fall below the minimum set value despite the values of index and ground speed.

  • Draper canvas with a shaped edge
    Patent number: 8291686
    Abstract: A crop harvesting header with a cutter bar and a draper assembly has a draper canvas with an edge portion across a front edge to cooperate with a rearwardly projecting element of the cutter bar extending over the upper run of the draper canvas to engage the upper surface of the edge portion to form a seal to inhibit entry of dirt or crop between the cutter bar and the draper canvas. The edge portion of the canvas is thicker and is canted upwardly at an angle of the order of 10 to 20 degrees. There is also provided a bead on the canvas on the surface opposite the strip within the width of the strip. The arrangement can be symmetrical with a strip at each of the front and rear edges spanned by the slats extending between them.

  • Crop pick-up assembly
    Patent number: 8286412
    Abstract: A crop pick-up frame has mountings for attachment to the feeder house of a combine harvester with a pick up assembly having transverse tine bars parallel to a transverse axis which move in a composite movement both around the transverse axis and parallel to the transverse axis such that each tine describes a closed path around the transverse axis and inclined to a radial plane of the transverse axis. Behind the bars is a belt conveyor followed by a converging auger where the belt conveyor is offset to one side relative to the bars so that the ends of the bars define a first path of travel at a first end of the bars and a second path of travel at a second end of the bars and the belt conveyor is offset such that one side edge extends beyond an outermost part of the second path of travel.
