  • Patent number: 10827677
    Abstract: A draper header for a harvester useful for providing hydraulic lifting and lowering of ground wheels. Hydraulic cylinders are capable of being actuated to independently lower and raise the ground wheels of the header while using the floatation pressure from the lift cylinders of the harvester. First and second hydraulic cylinders are fluidically coupled to a charge pressure of the harvester, the charge pressure providing a floatation pressure to position first and second ground wheels at a lowered operation mode and a raised operation mode.

    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.

  • Patent number: 7877974
    Abstract: A floating swathgate for a cutting and conditioning header for a frame-supported tractor in which the angular attitude of the swathgate relative to an airborne stream of crop material being ejected from conditioner apparatus is varied as the header moves vertically with respect to the tractor to optimally direct the crop material toward a rearwardly disposed crop merger conveyor. As the header moves vertically, changes in the angular attitude of the swathgate direct the airborne crop material to generally the same location on the merger conveyor to minimize crop losses that typically occur with a fixed swathgate when the crop trajectory varies directly with the header vertical movement.

  • Patent number: 7877975
    Abstract: A windrow merger lift mechanism having on a pair of rotational axes, skewed with respect to each other, to manipulate a merger apparatus between working and non-working positions. When the merger apparatus is in a first, or working position, the lift mechanism positions it to receive crop material from the conditioner rolls with minimal losses. When the merger apparatus is in a second, or non-working position, the lift mechanism positions the merger apparatus to allow crop material to be discharged from the header/conditioner with the same efficiency as a windrower having no installed merger attachment. The skewed axes of the merger lift mechanism optimize the merger position in both the working and non-working positions by moving the merger apparatus in four distinct, but related degrees of motion as the merger apparatus is moved between the positions.

  • Patent number: 7823372
    Abstract: A mower-conditioner is equipped with a double windrow attachment comprising a longitudinal conveyor which receives crop delivered rearwardly by a rotary conditioner. A side conveyor is located rearward of the longitudinal conveyor and is mounted for movement between a lowered operating position, wherein it is positioned for receiving crop conveyed rearwardly by the longitudinal conveyor, and a raised inoperative position wherein it permits the rearwardly conveyed crop to freely fall to the ground. The longitudinal conveyor is a roller conveyor with the rollers axes in a first embodiment comprising three sets of right- and left-hand rollers with the rollers of each set being skewed relative to a line extending perpendicular to a forward direction of the mower conditioner such that the axes of each set of rollers diverge rearwardly. In a second embodiment the rollers of each set are skewed such that their axes diverge forwardly.

  • Patent number: 7757469
    Abstract: A carousel merger is provided that is designed to replace existing belt conveyor devices. The carousel merger device has a crop receiving passageway which extends through a top surface of the carousel merger device toward a bottom surface of the carousel merger device. The crop receiving passageway has a plurality of crop receiving regions and a crop flow region. The crop receiving regions have arcuate sidewalls, support plates rotatably mounted to the bottom surface and blades mounted to the support plates. The crop flow region is provided adjacent the crop receiving regions with a portion of the crop flow region extending through the crop receiving regions. The crop flow region has a back wall opposite from the arcuate sidewalls of the crop receiving regions. A discharge is in communication with the crop flow region.

  • Patent number: 7743594
    Abstract: A mechanism for guiding a windrower while making an initial swath pass in a multi-pass windrow merging operation in a manner to establish the lateral spacing between an end of the header and the adjacent edge of the uncut crop so that the header encounters an optimal width of standing crop in a subsequent swath pass. The mechanism is selectively positionable between deployed (working) and stowed positions to maintain machine maneuverability when not in use. The mechanism further incorporates provisions to prevent damage to the mechanism resulting from inadvertent encounters with obstacles.

  • Patent number: 7673439
    Abstract: An agricultural machine for grouping windrows together or for windrowing products lying on the ground includes a main frame supporting a central gathering and windrowing device and two side gathering and windrowing devices connected to support arms that extend laterally during work. Each of the side support arms is articulated relative to the main frame on a substantially vertical axis about which it is foldable at an angle of approximately 90° for transport and each of the side gathering and windrowing devices is articulated on its support arm around a substantially horizontal axis about which it is foldable upwards at an angle of approximately 90° to obtain a reduced machine width for transport.

  • Publication number: 20090272090
    Abstract: A flexible tall crop knockdown barrier for use with rotary cutting headers in harvesting specialty crops such as grass seed. The knockdown barrier comprises a support frame mounted to the front of the header that extends forwardly and upwardly ahead of the header. A flexible barrier supported by the frame extends downwardly during idle conditions and downwardly and rearwardly as the header is propelled through the crop. The flexible curtain may be rolled around a lower spool and stowed on the support frame when not in use to improve visibility. The knockdown barrier serves to gently lean the crop forward before cutting so as to minimize seed shatter due whipping of the seed head.
