Abstract: A feederhouse assembly for an agricultural harvester includes a frame, a header lock pin, a biasing member coupled to the frame and the header lock pin, and a latch coupled to the frame and the header lock pin. The biasing member is configured to urge the header lock pin outward to lock a harvesting header to the frame. A rotatable latch in a first positron protrudes from the frame and retains the header lock pin in an inward positron. The latch in a second position permits the header lock pin to travel outward. A method includes applying a force from a harvesting header on a latch protruding from a frame of a feederhouse, pushing the latch to release a header lock pin from an inward position, and urging the header lock pin outward to lock the harvesting header to the frame.

Abstract: A straw chopper for a combine harvester including a rotor supporting a plurality of chopping elements. A rotor housing including an inlet opening, an outlet axially aligned with the inlet opening, and at least one outlet that is axially offset from the inlet opening. A portion of the straw is conveyed tangentially to the axially-aligned outlet, whilst a further portion is conveyed from the inlet opening to the axially offset outlet(s) via a path having an axial component, for example a helical path. Guide vanes may be provided on the inside of the housing to impart an axial force upon the straw.

Abstract: A mini-hopper for an agricultural row unit that has a fill tube supplying material to a hopper. A backflow preventer is disposed in the fill tube or in a line to the inlet to prevent flow of material from the mini-hopper through the fill tube when the mini-hopper is in a transport position.

Abstract: A sickle guard counter-knife insert includes a pair of counter-knives. Each counter-knife defines a channel for an operable sickle bar between mutually-coupled upper and lower portions. The counter-knives and a connecting crossbar are formed together as an integral unit.

Abstract: A combine harvester including a grain tank having an auger trough in which a screw conveyor of an unloading system is disposed. The screw conveyor is operable to define an upturning side and a downturning side. The grain tank includes a floor section that covers the upturning side to prevent back flow and the formation of a stagnation zone in the vicinity thereof.

Abstract: A chain and slat conveyor with first and second continuous chains and a plurality of slats. Each slat is connected to the first chain by a keyhole connection and to the second chain by a bolt or rivet which passes through a hole in the slat.
