Abstract: A combine for harvesting a harvested material that includes a grain, the combine comprising: a threshing chamber comprising a series of threshing and separating apparatuses, sequentially arranged, comprising at least: (i) a straight bar concave (ii) a first round bar concave, and (iii) a second round bar concave. The size of each of the straight bar throats is smaller than a size of the first openings, and the size of each of the first openings is smaller than the size of each of the second openings.

Abstract: A stalk roll having twelve flutes extending radially from the main cylinder along the length of the main cylinder. Within the row unit opposing stalk rolls cooperate to engage and capture the corn stalk, thereafter, controlling and processing the corn stalk. The flutes may be configured with differing edges to facilitate control and movement of the stalk to the point of ear separation within the row unit. The flutes may be configured such that opposing compressive forces acting on the exterior of the stalk at approximately 180° of separation operate to implode the stalk while sharp edges on the flutes operate to cut the stalk into small segments which are deposited on the ground for decomposition.

Abstract: A stalk roll may be configured to be mounted upon a stalk roll drive shaft of a corn harvesting header, wherein the stalk roll drive shaft has a generally square cross-sectional shape. The stalk roll may comprise a main cylinder with a plurality of flutes extending radially from the main cylinder along the length of the main cylinder. A taper may be positioned toward the front end of the main cylinder. The flutes may be configured such this with differing edges to facilitate stalk movement into and through the ear separation zone to the plant separation zone. The flutes may be configured such that a bladeless area proximate to the nose cone on each of two stalk rolls of an opposing pair cooperate to form at stalk engagement gap in at least one moment in time per revolution of the stalk rolls.

Abstract: Methods and systems utilize multiple components to improve the threshing operation within an agricultural combine. The methods and systems include a unique concave design, open valley rasp bars, and restrictor plates. Application of the methods and systems' 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.

Abstract: A MOG limiting device, herein described as a MOG limiter, approximates a portion of the curvilinear length of a concave. The MOG limiting device can include a connection point near the middle of a concave, slightly offset from center. A bolt, washer and nut assembly protrudes downwardly from the underside of the concave. Two assemblies are positioned in the middle of each side of the concave. The assemblies cooperate with a mounting plate on the MOG limiters to form an upper concave connection and a lower concave connection in each half of the concave. In the cross frame, insert slots are positioned to receive a hinge point located at the end of each arced member making up the frame (rail supports). The hinge points are slidably inserted into the opening and then rotated upwardly to be positioned adjacent to and in conformity with the curvature of the underside of the concave with the connection assemblies holding the MOG limiter in place.

Abstract: One embodiment of a stalk roll to be mounted upon a stalk roll drive shaft of a corn harvesting header comprises a cylindrical shell with a recess in the main cylinder, wherein reduced flutes are not present in the recess, but full flutes are present therein. This embodiment includes a stalk slot having a length equal to the length of the recess. Additionally, the flutes may be configured such that a stalk engagement gap is present at least once during a full revolution of two opposing stalk rolls.

Abstract: A flute for a stalk roll has a sharp edge defined by the relationship of the leading surface and a leading wall. The flute is positioned on a main cylinder of said stalk roll having a leading surface having its base nearer the main cylinder and its top farther from the main cylinder, the leading wall, and a trailing wall. The leading wall extends perpendicular to and outward from said main cylinder. The base of the leading surface intersects the leading wall and travels upwardly to intersect with the trailing surface to form an edge. The angle between the leading wall and leading surface is thirty degrees.

Abstract: A method for creating a narrow row head unit which may include a back plate secured to a left gearbox and a right gearbox, and which gearboxes may be positioned adjacent one another. Each gearbox may provide rotational power to a pair of stalk rolls and a drive sprocket for a gathering chain. A right mounting tab may be secured to the back plate and the right gearbox, and a left mounting tab may be secured to the back plate and left gearbox. A right plate and leg may extend outward from the back plate adjacent the right mounting tab and a left plate and leg may extend outward from the back plate adjacent the left mounting tab. A narrow row head unit positioned left-of-center on a header may have the gathering chain positioned substantially over the right plate, and right-of-center substantially over the left plate.

Abstract: 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.
