Abstract: A faceplate sub-assembly for an agricultural vehicle includes a faceplate and at least one biasing element. The faceplate is configured to be connected between (i) a feederhouse defining an inlet opening through which crop material is delivered for processing by the agricultural vehicle, and (ii) a header of the agricultural vehicle. The faceplate is configured to be pivotably mounted to the feederhouse such that the faceplate is configured for lateral tilting relative to the feederhouse. The at least one biasing element has one end connected to the faceplate and another end that is configured to be connected to the feederhouse for reducing a friction force at the interface between the faceplate and the feederhouse to accommodate lateral tilting of the faceplate.

Abstract: A cutter bar assembly for an agricultural vehicle header includes a cutter bar supported by movable arms extending from a header frame and capable of operation in flex and rigid modes. The support arms are joined to the header frame such that they may be displaced from a raised position in the rigid mode when subjected to a lifting force due to striking an obstacle without damage to the header structure. Also, an agricultural vehicle header and an agricultural combine harvester includes the cutter bar assembly.

Abstract: An adjustable stalk stomper and/or chopper curtain assembly for a header of an agricultural harvester. The adjustable assembly comprises a control arm, at least one member connected to the control arm, wherein the at least one member is configured to knock down plant stalks and/or to shield the agricultural harvester from flying debris, and wherein the control arm is configured to provide for adjustment of the orientation of the at least one member relative to the ground and the header. An agricultural harvester header may include the above adjustable assembly and a frame having a toolbar. An agricultural harvester may include such header.

Abstract: A knife head drive assembly for a header of an agricultural harvester including a knife head assembly for attachment to a forward end of the header. A first pivot arm and a second pivot arm are carried by the knife head assembly and are pivotably connected by a linkage. A rotating crank is operatively connected to and extending substantially transverse to the knife head assembly for engagement with a drive. A reciprocating shaft is connected to the rotating crank and either of the pivot arms or the linkage. Operation of the knife head drive assembly results in substantially linear, opposed oscillating motion of cutter bars carried by the knife head assembly.

Abstract: A harvesting reel assembly for a header of an agricultural harvester is disclosed. The harvesting reel assembly includes a central rotatable shaft, a plurality of support members, a cam assembly and an extendable reel arm. The plurality of support members extend widthwise across the reel assembly and connect to the central rotatable shaft for rotation therewith. The cam assembly guides rotation of the plurality of support members. The extendable reel arm includes a first end engaged with the central rotatable shaft for rotation therewith. The extendable reel arm also includes a distal end opposite the first end connected to one of the plurality of support members.
