Systems, methods, and apparatuses for automatically controlling a position of a reel relative to wing of an agricultural header in response to movement of the wing are disclosed. In some instances, a position of the reel, such as a portion of the reel, is located at a different position relative to the wing based on an amount of articulation of the wing, such as an amount of angular displacement of the wing relative to a datum, such as a center frame of the header.

An agricultural vehicle includes a chassis and a header carried by the chassis. The header includes: a header frame; a cutter movably coupled to the header frame; a reel arm pivotably coupled to the header frame; a reel carried by the reel arm and including a plurality of tines; a variable displacement fluid cylinder including an interior chamber, a first piston linked to the reel arm placed within the interior chamber and a second piston placed within the interior chamber, the interior chamber defining a shared volume between the first piston and the second piston; and a piston driver linked to the cutter and configured to translate movement of the cutter relative to the header frame into displacement of the second piston within the interior chamber.

An improved telescopic reel includes a telescopic supporting frame and a central module including at least one bracket constrained to the supporting frame and connectable to a bearing and/or guide through a fastener. The bearing and/or guide is adapted to bear and guide, during its rotary motion, at least one transversal intersection element of the reel; the bearing and/or guide being positioned on the at least one intersection element at a first distance from a longitudinal central shaft of the reel, the first distance being greater than or equal to a second distance between the central shaft and a crosspiece of the reel.

In a harvester/header combination according to the invention, the header is a crop pick-up header (2) coupled to a forage harvester (1). The header comprises a frame (10) and a rotatable reel (13) configured to collect crops from the ground, a rotatable auger (20) provided with two oppositely wound helicoidal flights (26), and one or more windguard rolls (15). The auger is rotatable with respect to a pair of support arms (21) which are themselves pivotable relative to the frame, so that the pivoting movement of the arms results in lowering or raising the auger (20). According to the invention, the header comprises at least one set of actuators (18.19) capable of actively raising the auger and the windguard roll(s) and the harvester/header combination comprises a control unit (46) configured to execute a sequence of steps for removing a foreign object from the header, after detection of the object and stoppage of the harvester's feed rolls (51). The removal sequence includes raising the auger while rotating the auger in the reverse direction, followed by lowering the auger while maintaining said reverse rotation.
