An agricultural motor vehicle able to connect to a variety of agricultural implements, and comprising a structural set having four parts: a lower chassis, an intermediate structure, a front complementary structure, and a rear complementary structure. The set is supported over a set of front traction wheels and a set of smaller rear wheels and also houses a vibrating sieve, above which is located a beating cylinder, the front edge of which connects to a concentrating guiding roller and a hinged inlet nozzle, as well as a cockpit and a grain dumper located over the set. Preceding the grain dumper is a clean grain collection gutter, a motor power set, a suction cleaning set, a clean grain elevator and lastly, a retractable side belt, whose lower edge is hinged at its midpoint and located on the upper edge of the intermediate structure.

A concave for an agricultural combine includes threshing beds carried by a base frame and forming openings therebetween for grain to pass through. Each threshing bed includes a first end, a second end, a length from the first end to the second end, an inner extremity, an outer extremity, and a separating grate extending across one of the openings for separating grain from threshed crop material. The separating grate extends along the length between the first end and the second end, is between the inner extremity and the outer extremity and includes grate openings and spaced-apart bars. The bars are between adjacent grate openings and include struts each connecting two adjacent parts of the separating grate between adjacent grate openings and severed bars each including bar segments extending inwardly toward one another to respective free ends on either side of a gap between adjacent grate openings.

A combine for harvesting chick peas includes a first rotatable shaft having components that cut a crop and pass the cut crop in a rearward direction, and a drum that includes an outer shell with stationary threshers and a cut crop opening, a rotatable central mount, a plurality of rotatable threshers. Each of the rotatable threshers is attached to the central rotatable mount and in line with a stationary thresher. A plurality of cutters is attached to the outer shell, a flame source projects a flame into the drum, and a water source projects water into the drum. The cut crop passes into the cut crop opening, to be further cut by the plurality of cutters and threshed by the plurality of rotatable threshers, such that the flame and water are projected onto the cut crop, resulting in a processed crop and detritus that is separated from the processed crop.

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 cutting and threshing blade for a bush hog, wherein the blade has a trailing edge and a leading edge. At least a third of the leading edge of the upper-side of an elongate distal portion of the blade has a knife edge with a knife length that thickens toward the trailing edge. The trailing edge can have an upward air deflector. The bottom-side of the elongate distal portion has a threshing element, which includes a threshing block, which is a steel block having a block length that is comparable to the knife length and projects downward and substantially parallel to the knife edge. The rotating blades pummel growth carriers (i.e.; cob, husk) bearing seeds, grains, and kernels with enough force that they are released. The synergistic rotating knife edge and threshing block transform the bush hogging process from a cutting process to a cutting and threshing process.

A thresher for a combine harvester has a concave cage and a rotor disposed within the concave cage. The rotor carries material manipulators that extend outward from the rotor toward the cage to manipulate material in the concave cage as the rotor rotates. One or more air nozzles are provided that direct air outward from the rotor and toward the concave cage. A source of forced air circulates air through the one or more air nozzles.

A threshing section of an agricultural harvester. The threshing section includes a threshing drum and at least one concave assembly positioned proximate to the threshing drum. The concave assembly has a plurality of modularized assemblies, each modularized assembly being independently configurable.
