An agricultural harvester comprises a feederhouse pivotally attached to a chassis, where the feederhouse defines a conduit for conveying crop material rearwardly from a front opening. A header interface frame is pivotally mounted to the feederhouse over the front opening to permit header pitch adjustment around a pitch adjustment axis. Upper and lower linear actuators are connected on one side of the feederhouse between the feederhouse and interface frame to control the pitch adjustment.

A reel arm for a header of an agricultural harvester comprising a rotatable coupler, a first linkage assembly and a second linkage assembly is disclosed. The rotatable coupler has a central rotational axis and includes a control shaft extending therethrough parallel to the central rotational axis. The first linkage assembly includes a first end connected to the control shaft about a first lateral side of the rotatable coupler and a second end opposite the first end for connection to a reel tine bar of a first reel assembly of the header. The second linkage assembly includes a first end connected to the control shaft about a second lateral side of the rotatable coupler and a second end opposite the first end for connection to a reel tine bar of a second reel assembly of the header.

A feederhouse assembly for an agricultural vehicle includes a feederhouse frame including at least four interconnected walls, an open front end, an open rear end, and a hollow space circumscribed by the four interconnected walls. A header adapter is moveable relative to the feederhouse frame. The header adapter has an adapter sidewall disposed adjacent a feederhouse sidewall of the four interconnected walls. A torque stop is positioned within a gap formed between the feederhouse sidewall and the adapter sidewall. The torque stop has a low-friction bearing surface that is configured for bearing directly on one of the adapter sidewall and the feederhouse sidewall upon deformation of the frame to reduce friction between the adapter sidewall and the feederhouse sidewall.

A flexible and rotatable coupling assembly for a feeder conveyor of a combine harvester, for example. The coupling assembly connects a first rotatable shaft to a second rotatable shaft. The coupling assembly includes a spherical bearing that is connectable to the first rotatable shaft for accommodating a radial or angular misalignment between the first and second rotatable shafts; and a flexible and rotatable coupler that is non-rotatably connectable to the first and second rotatable shafts for transferring rotation between the first and second rotatable shafts. The flexible and rotatable coupler is either directly or indirectly connected to the spherical bearing. The flexible and rotatable coupler has a flexible component for accommodating the radial or angular misalignment.

A finger support for the fingers of a rotating drum conveyor (e.g. feed drum) and agricultural harvesting head includes first and second finger supports with first and second ring portions fixed together to define a gap into which a third ring portion is received and supported.

A header drivetrain coupling system including a harvester driveline mounted to a harvesting vehicle and a header driveshaft mounted to a detachable header. The harvester driveline is supported for rotation at an inboard end on a feederhouse and at an outboard end on a header tilt frame even when the header is detached therefrom. The harvester driveline comprises a telescopic portion which permits a coupling member on the outboard end to be moved into and out of engagement with a coupling member on the header driveshaft. A sliding support assembly is provided to support a bearing housing which holds the outboard end of the harvester driveline on the tilt frame. An actuator is configured to move the bearing housing with respect to the tilt frame to selectively engage and disengage the coupling members.
