An agricultural vehicle includes a chassis, a threshing and separating mechanism supported by the chassis and configured for threshing and separating a crop material, a cleaning system positioned downstream of the threshing and separating mechanism in a direction of crop material flow, and an auxiliary processing system positioned downstream of the threshing and separating mechanism in the direction of crop material flow. The auxiliary processing system has an inlet and an outlet, and includes a discharge chopper having an end and a first direction of rotation about an axis of rotation. The auxiliary processing system also includes at least one rethreshing element coaxially aligned with the discharge chopper and adjacent to the end of the discharge chopper and having a second direction of rotation opposite to the first direction of rotation of the discharge chopper.

A threshing and separating system including a rotor cage, a first vane rail movably connected to the rotor cage, and a first vane portion with a first constrained end pivotably connected to the rotor cage and a first movable end linked to the first vane rail. The threshing and separating system further including a second vane rail movably connected to the rotor cage, and a second vane portion with a second constrained end pivotably connected to the rotor cage and a second movable end linked to the second vane rail, the second vane portion and the first vane portion together define a substantially continuous vane.

A kit and method of abrading grain provides multiple components to improve the threshing operation within an agricultural combine. The kit includes a unique concave design, open valley rasp bars, and restrictor plates. The method of abrading grain allows threshing operations for large grains such as corn and, also, for small grains such as soybeans. For example, the kit can be used to facilitate construction of a harvesting system that comprises: a drum of a rotary combine; a straight bar concave in a first position, wherein the straight bar concave utilizing intersecting bars, wherein at least some of said intersecting bars including a sharp leading edge, wherein the sharp leading edge abrades harvested materials and separate grain therefrom when the rotary drum rotates; and a plurality of round bar concaves in at least a second and a third position.

A kit provides multiple components to improve the threshing operation within an agricultural combine. The kit includes a unique concave design, open valley rasp bars, and restrictor plates. Application of the kit components allows more efficient threshing operations for large grains such as corn and, also, for small grains such as soybeans resulting in an increased capture and retention of seed from the threshing operation.

A threshing drum and a combine using a threshing drum are disclosed. The threshing drum comprising a drum body and beater bars. The beater bars each have a beating edge which describes a circumferential circle about a center axis of the drum body, on which the particular beating edge rotates about the center axis in a beating radius during operation of the threshing drum. To improve a flow of harvested material while the flow is being transferred from a threshing device to a downstream separating device, a cutting ring is positioned centrally on the drum body, viewed in the longitudinal direction of the drum body, which rotates in the circumferential direction of the drum body. The cutting ring has at least one circumferential cutting edge which describes a circumferential circle whose cutting radius, measured with respect to the center axis, is greater than the beating radii of the beating edges.

A harvesting machine that has a first rotor rotationally coupled to a chassis, a second rotor rotationally coupled to the chassis, and a spine separating the first rotor from the second rotor. Wherein the spine has threshing inserts coupled thereto to facilitate threshing of crop processed by the first and second rotors.

Provided is a threshing cylinder with a threshing processing section provided on the rear side of a raking section. In the threshing processing section, a front support member, an intermediate support member, and a rear support member are supported by a threshing cylinder support shaft. A plurality of front-side divided threshing teeth support members are supported by the front support member and the intermediate support member in a state in which the front-side divided threshing teeth support members are arranged at the same arrangement pitch in the circumferential direction of the threshing processing section. A plurality of rear-side divided threshing teeth support members are supported by the intermediate support member and the rear support member in a state in which the rear-side divided threshing teeth support members are arranged at the same arrangement pitch in the circumferential direction of the threshing processing section.

A material processing system having a barrel also referred to hereinafter having a milling or impact surface and a central axis. The impact surface is impervious, in that material cannot pass through the surface, but rather is contained by the surface. An impact mechanism is located within barrel and is rotates about the central axis. The system has inlet openings and formed in the barrel at axially spaced locations along the axis. At least one outlet opening is formed in the barrel at a location intermediate of the inlets. The impact mechanism includes a plurality of hammers mounted on shaft which rotates about the axis.
