Method for operating an agricultural harvester (1), wherein the agricultural harvester (1) has an attachment (2), wherein the attachment (2) has a receiving conveyor (7) which is driven at a defined first speed, wherein the attachment (2) has a discharge conveyor (8) which is driven at a defined second speed, wherein the harvester (1) has an infeed unit (4) with infeed rollers (5, 6) which are driven at a defined third speed. The second speed, at which the discharge conveyor (8) is driven, is determined depending on the third speed, at which the infeed rollers (5, 6) are driven, and also depending on the speed of travel of the agricultural harvester (1).

An attachment for connection to a harvester comprises a plurality of picking devices (2) arranged next to each other and in a distributed manner along the working width. Each picking device (2) has a picking gap (6), below which are disposed at least two picking rotors (10) which can be driven to rotate in opposite directions, the picking rotors (10) being provided with flutes (12), which project in a radial direction beyond the rotor casing (16) and the enveloping circles (20) of which mesh with each other. To propose a way of easily adapting the picking rotors to different harvesting conditions without having to replace them all, the invention proposes for one or more shear bars (18) which are releasably connected to the picking rotor (10) and/or to the flutes (12) to be inserted in the intermediate space (22) between adjacent flutes (12) of a picking rotor (10), the shear bars filling portions of said intermediate space during a rotating movement of the picking rotors (10).

A crop head for a harvester includes a folding frame having a first frame portion and a second frame portion configured to be folded in a transport state and unfolded in a harvesting state. The first and second frame portions are lockable with respect to each other to inhibit folding and unlockable with respect to each other to allow folding. A plurality of crop dividers is supported by the first frame portion. The plurality of crop dividers includes at least one movable crop divider that is movable with respect to the first frame portion. The crop head also includes a cylinder and a piston movable with respect to the cylinder. The piston is operable to move the movable crop divider between the first and second positions and is configured to directly engage the first and second frame portions to lock the first and second frame portions with respect to each other.

A corn harvesting header (24) includes a powered row unit (38) and a gathering hood (98). The row unit (38) defines a longitudinal crop row path that extends in a generally rearward crop travel direction and receives a corn row as the header (24) is advanced along the corn row. The gathering hood (98) partly overlies the row unit (38) and includes a laterally extending dam (132) that restricts corn from moving forwardly. The dam (132) at least partly defines a gutter to receive corn kernels and direct the corn kernels rearwardly.

An agricultural implement includes a first central implement section. At least one second implement section is positioned on each of two sides of the first implement section. Adjacent implement sections are each displaceable relative to one another about a pivot axis in order to displace the implement between a transport position and a working position. Each implement section comprises mowing mechanisms, conveying mechanisms or both. A hat-like conveying element made from an elastically deformable material is positioned on at least one of the mowing mechanisms, on at least one of the conveying mechanisms or both.

A chopper assembly having a discharge conduit. A first and a second beater disposed within the discharge conduit and a first door and a second door in the bottom wall of the discharge conduit positioned below the first beater and the second beater respectively.

A non-row sensitive forage harvester header utilizes a single rotary transfer member to convey severed crop material from the forwardly positioned rotary cutting members to the feed rolls of the forage harvester. A fixed guide plate dislodges severed crop from the right cutting member to transfer the crop material to the left cutting member to convey the crop further rearwardly to the rotary transfer member. Additional fixed guide plates establish a flow path for the severed crop material and facilitate the movement of the severed crop from the left cutting member to the rotary transfer member and then to the feed rolls. A drive mechanism is provided to power the rotation of the cutting members and the rotary transfer member with a cutting disk on each cutting member being driven faster than the multiple crop engaging members also carried on the cutting members above the cutting disk.

A cutting disc for a machine for harvesting stem-like plants includes a number of elements which together can be attached or are attached to a bracket forming a circular ring with an outer cutting edge. At least one of the elements is attachable to the bracket in a first position, in which a first edge of the element forms the outer cutting edge, and in a second position, in which a second edge of the element forms the outer cutting edge. No matter whether the element is in the first of second position, a circular cutting edge is made up.

A cutting device is embodied for cutting agricultural crop plants by a rotational movement about a cutting rotation axis and has at least one knife element that, in a plan view of a top side of the cutting device, is embodied open in circulating direction. At least one radial conveying element, arranged at least at the top side and stationary relative to the knife element, is provided that at least in sections thereof is embodied for conveying the crop plants in a conveying direction that, relative to the cutting rotation axis, is oriented partly tangentially and partly radially relative to the cutting rotation axis. Moreover, a harvesting attachment with a plurality of such cutting devices and a field chopper with such a harvesting attachment is provided.

A crop head for a harvester includes a folding frame having a first frame portion and a second frame portion configured to be folded in a transport state and unfolded in a harvesting state. The first and second frame portions are lockable with respect to each other to inhibit folding and unlockable with respect to each other to allow folding. A plurality of crop dividers is supported by the first frame portion. The plurality of crop dividers includes at least one movable crop divider that is movable with respect to the first frame portion. The crop head also includes a cylinder and a piston movable with respect to the cylinder. The piston is operable to move the movable crop divider between the first and second positions and is configured to directly engage the first and second frame portions to lock the first and second frame portions with respect to each other.
