  • Patent number: 8118650
    Abstract: An adjustable flow distributor for a spreader of an agricultural combine operable for discharging a flow of straw and other crop residue in a sideward direction for deposition over a field, the flow distributor including an edge portion oriented at an oblique angle to a reference such as a back plate of the spreader, defining an oblique shaped space therebetween, the edge portion being pivotally adjustable in the fore and aft direction for controlling the portions of the flow of crop residue deposited beneath the spreader and discharged sidewardly therefrom, respectively, for instance, so as to better and more evenly distribute the crop residue over a swath of an agricultural field from which the crop was harvested, particularly a region of the swath in proximity to the spreader and/or chopper.

  • Patent number: 8092286
    Abstract: A concave pan portion of an integral chopper assembly that includes a concave pan shell portion with a separate grate portion that may be easily installed into and removed from an intermediate opening in such concave pan portion for replacement in the event of undesirable wear thereto, and a separate interruption plate installable downstream from the slots in the grate portion for the purpose of effecting a lower mean length of chop (LOC) as the integral chopper assembly operates. The separate grate portion is configured to be installable to fill the intermediate opening in the concave pan shell portion, with a plurality of slots therethrough positioned side by side in the crossways direction to accommodate knife elements that are part of the counter knife assembly.

  • Patent number: 8006926
    Abstract: A knife bank assembly of a counter knife assembly of an integral chopper assembly of a combine harvester that includes an elongated bracket member that extends between opposed knife bank end plates and has a plurality of spaced retainment mounts securable therealong, with at least one, and preferably two, knife blades being removably connectable to each retainment mount in a side by side arrangement. The knife elements are removably connectable to the retainment mounts at first and second space mounting points, preferably in such a way that the knife elements are maintained in an extended position by application of a biasing force at the second mounting point but are rotatable about the first mounting point to a displaced or relaxed position if a sufficient force is applied to the leading edge of the knife element to overcome the biasing force.

  • Publication number: 20100267433
    Abstract: The concave adjust assembly uses a torsion axle connecting a drive to a concave. The torsion axle includes an inner element having an angular sectional shape, a tubular outer element disposed about the inner element and having a larger angular sectional shape oriented such that corners of the tubular element are disposed opposite flats of the inner element, the elements being laterally relatively rotatable, and damping elements disposed between the inner and outer elements such that the rotation will compressively load the damping elements. The drive includes a motor, such that operation of the motor will adjustably move the concave, and the damping elements will damp impulse loads generated from threshing, to reduce transmission of the loads to the drive.

  • Publication number: 20090253474
    Abstract: A vertical spreader of a combine harvester has a reflexing deflector elements hingedly secured to a flow guide element, and the deflectors are reinforced by over-center linkage so as to automatically hinge in response to the positive pressure of an oversized wad of crop residue and/or by loss of impeller speed. The wad is thereby discarded, and the deflector elements thereafter return to the original position held prior to hinging.
