Abstract: 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.

Abstract: A lubricating oil maintenance cap assembly includes a cap having an outer side, and an inner side, a shield, anchor assemblies, the shield is applied to the inner side of the cap, and the anchor assemblies anchor the shield to the cap. The cap is fashioned of a first material, the shield is fashioned of a second material, and the second material is different from the first material and is more thermally resistant than the first material enabling the shield to thermally shield the inner side of the cap.

Abstract: A concave for an agricultural combine includes threshing bars carried by a base frame and forming openings therebetween for grain to pass through. Each threshing bar includes an inner extremity, a deflecting extremity including a deflecting surface, a separating grate between the inner extremity and the deflecting extremity, the separating grate extends across an adjacent one of the openings between the inner extremity and the deflecting extremity for separating grain from threshed crop material, the deflecting surface projects angularly upward relative to the separating grate, and the deflecting surface and the separating grate are arranged at an obtuse angle therebetween forming a grain-collecting trough between the deflecting surface and the separating grate.

Abstract: A concave for an agricultural combine includes first and second frames and a threshing mat that includes threshing bars each including a separating grate. An engagement assembly non-destructively connects each of the threshing bars to the first frame, the threshing bars form openings therebetween for grain to pass through, the separating grate of each of the threshing bars extends across an adjacent one of the openings for separating grain from threshed crop material, and the separating grate of each of the threshing bars is fixedly connected to an adjacent one of the threshing bars. The engagement assemblies enable non-destructive removal of the threshing mat from the first frame, when the second frame is spaced apart from the first frame. The second frame restrains non-destructive removal of the threshing mat from the first frame via the engagement assemblies, when the second frame is juxtaposed to the first frame.

Abstract: A concave for an agricultural combine includes first and second frames connected together for movement between closed and open positions. The first frame includes curved members axially spaced from one another, and bars each movable between a first position removably connected to the first frame and a second position detached from the first frame, wherein the bars are spaced from one another and extend axially between the curved members forming openings therebetween for grain to pass through in the first position of each of the bars. The second frame restricts movement of each of the bars between the first and second positions in the closed position of the first and second frames, and the second frame allows movement of each of the bars between the first and second positions in the open position of the first and second frames.

Abstract: A concave for an agricultural combine includes a frame having curved members, and angle members each having opposite ends, a corner segment, a straight threshing segment including a threshing edge, and a straight separating segment having a separating grate. Each of the opposite ends of each of the angle members is non-destructively held in a respective one of a plurality of corresponding angle slots of the curved members.
