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 system processes seeds that are present in crop material. The system includes a first shearing surface, a second shearing surface arranged opposite the first shearing surface, and a clearance between the first shearing surface and the second shearing surface. The system passes crop material between the first and second shearing surfaces, where the crop material contacts the shearing surfaces as it passes through the shearing surfaces. Contact with the first and second shearing surfaces damages seeds that are present in the crop material. The system can be installed in an agricultural harvester to damage seeds that are present in crop residue to prevent the seeds from germinating after the crop residue is discharged from the agricultural harvester back into the field.

A spreader system of an agricultural vehicle for spreading crop residue including a spreader device and a fan. The spreader device includes a plurality of paddles configured to rotate about a first axis, with the rotation of the paddles producing a stream of crop residue. The fan includes a plurality of impellers configured to rotate about a second axis, with the rotation of the impellers producing a stream of air. The stream of air is directed to exit the spreader system beneath the stream of crop residue as the crop residue leaves the spreader device.

A procedure for collection and processing of weed seeds of the type which includes: a first step of collecting of a plant material; fourth step of threshing of the harvested material; a fifth step of separating of grains from material other than the grains; a sixth step of cleaning of the main material; a seventh step of transporting the main material to a discharge device; and an eighth step of storing the main material in an appropriate media. Also includes a second step of placing the material obtained by a thresher head assembly into at least one conveyor belt towards a trailer; a third step of transferring the plant material into a transport and hauling vehicle to a stationary processing plant; a ninth step of grinding the residues; a tenth step of introducing the MDG into densification device; and a tenth step of incorporating in a mixer the resulting grinding of the ninth step along with at least one supplement.

In a combine, each of a plurality of dust-sending valves 30B includes a first dust-sending member 31 provided in an upper portion of a threshing chamber 16 in a state of extending in a left-right direction of a threshing chamber and in a state in which a sending angle is changeable by swinging, and a second dust-sending member 32 provided in a state of being fixed to a position located on an upstream side in a rotation direction of a threshing cylinder with respect to the first dust-sending member 31 such that a sending angle is not changeable. A portion of a top plate 19 facing the second dust-sending member 32 has an arc shape as viewed in a direction along a rotation axis P of a threshing cylinder 20.

A helical auger flight has an inner edge, an outer edge, an inner face, an outer face, and a leading extremity that includes a prominence and a leading edge that extends from the outer edge to the prominence. The prominence extends outward from the leading edge of the leading extremity to an outer end having an upturned jut. A wear plate is releasably connected to the inner face of the helical auger flight. The wear plate extends from the outer edge of the helical auger flight to the prominence. A front extremity of the wear plate extends forwardly of the leading edge of the helical auger flight so as to be in a shielding relationship with respect to the leading edge of the helical auger flight, and a nose of the front extremity of the wear plated is seated in direct contact against a contact surface of the jut.
