  • Patent number: 9930824
    Abstract: A windrower has a first dual-path steering mode, causing a left drive wheel and a right drive wheel to concurrently rotate, wherein the rotation of the left drive wheel is in a direction opposite that of the rotation of the right drive wheel and the position of tailwheel casters are not controlled but are permitted unconstrained rotation. The windrower also has a second tailwheel steering mode non-overlapping in operation with the dual-path steering mode, causing the left drive wheel and the right drive wheel to rotate concurrently in only a same direction and the tailwheel casters are steered based in part on tailwheel caster steer position information received from a sensor.

  • Publication number: 20180051513
    Abstract: Disclosed is a harvesting combine having a cab for an operator, a wheel assembly adjacent to a stairs assembly having a top and a bottom, and an improved stairs assembly for accessing the cab by the operator. The improved stairs assembly in a deployed state is angled outwardly from the top of the stairs assembly. The stairs assembly is rotatably connected about its bottom to both raise the stairs assembly and move its bottom inwardly. The stairs assembly is movably connected by a track assembly about its top so as to permit the top of the stairs assembly to move inwardly and upwardly when the stairs assembly is raised from its deployed state. The stairs assembly may be angled outwardly from the top end of the stairs assembly to an angle from the vertical of greater than 15° and may be rigidly anchored at its lower end.

  • Patent number: 9775287
    Abstract: A harvesting header has an outer impeller fixed to an outermost outboard cutter for rotation therewith to convey cut crop material laterally inwardly toward the center of the header. The outer impeller has a lower disc member forming the bottom of an impeller cage and an upper stationary grass ring. An intermediate impeller is located between the axes of rotation of the two outboard cutters, wherein the intermediate cage-like impeller is suspended on the harvesting header above the cutting plane and not fixed to any of the cutters and rotates in the same direction as the outboard impeller. The outboard and intermediate impellers have a plurality of crop conveying discs, wherein the crop conveying discs on the outboard impeller are offset vertically and overlap horizontally with the crop conveying discs on the intermediate impeller to form an intermeshing region between the two impellers.

  • Patent number: 9736980
    Abstract: A harvesting header has a crop conveying element fixed to an outboard cutter of a cutter bed. The crop conveying element includes at least one slinger attached to an upstanding spacer to space the slinger apart from a top wall of the cutter. The slinger includes a flat disc with a plurality of lobes extending outwardly from a central portion thereof and the spacer is shorter than an outer impeller such that a top extremity of the slinger is spaced below an upper level of an outer impeller. The spacer is also smaller in diameter than the outer impeller so as to provide a space below the slinger to allow flow of the crop material over the second outboard cutter, the space between the top wall of the cutter and the slinger being at least half of the height between a lower disc member and upper stationary grass ring of the outer impeller.

  • Patent number: 9648809
    Abstract: A pull-type mower conditioner includes a crop cutting assembly that severs crop material from the ground and a lift mechanism configured to raise and lower the crop cutting assembly to a desired height having at least one lift cylinder and a hydraulic lift circuit supplying hydraulic fluid to the at least one lift cylinder. The mower conditioner also includes a conditioning mechanism receiving the severed crop material from the crop cutting assembly. The conditioning mechanism includes a pair of counter-rotating conditioning rolls to condition the crop material and a tensioning assembly that urges the conditioning rolls relatively toward one another and resists their separation. The tensioning assembly includes a pair of hydraulic tension cylinders and a hydraulic conditioner circuit configured to supply hydraulic fluid to the tension cylinders.

  • Patent number: 8733770
    Abstract: A working vehicle has a castor wheel assembly selectively providing steering assist. A pivoting caster spindle coupled with a caster wheel and an engagement plate connected to the caster spindle in a fixed manner such that the engagement plate pivots with the caster spindle. A pivoting steering arm is rotatably connected to the caster spindle and a steering cylinder is connected to an outward end of the steering arm with a tie rod configured to pivot the steering arm. A keyed connecting mechanism selectively couples the steering arm with the engagement plate. In an engaged position, the keyed connecting mechanism couples the steering arm with the engagement plate such that the steering cylinder pivots the caster spindle and caster wheel. In a disengaged position, the steering arm is uncoupled with the engagement plate such that the caster spindle and caster wheel are free to pivot independent of the steering cylinder.

  • Patent number: 8695316
    Abstract: A crop harvesting header has a cutter bed to cut crop material as the harvester advances through a field. The cutter bed includes a plurality of rotatable cutters having knives extending from opposing ends of the cutters. Each cutter is ninety degrees out of phase with respect to its adjacent cutters such that the circular paths of travel of the knives of adjacent cutters overlap one another, and adjacent cutters rotate in opposite directions. Each cutter has a generally elliptical knife carrier, and a pair of knives at opposites ends of the carrier, wherein a portion of each knife extends beyond the end of the carrier to expose a cutting surface to sever the standing crop. The cutter also includes an attachment device connecting each knife to the knife carrier, and a fixed stop restricting rotational movement of the knife with respect to the carrier about the attachment device.

  • Patent number: 8601778
    Abstract: In an example embodiment, a harvesting header includes a helper roll having an auger flighting configured to move crop material laterally inward. The auger flighting may be outboard of a crop receiving area. The helper roll may be placed rearward of a cutter mechanism and forward of a conditioning roll of the header. The axis of rotation of the helper roll may be positioned slightly above a cutting plane of a cutting bed so that the auger flighting extends vertically past the cutting plane. In an example embodiment, at least a portion of the auger flights are positioning outboard of a conditioning roll of the header. The helper roll may be supported within the cutting zone and comprised of a plurality of sub-helper rolls.
