A non-row sensitive forage harvester header is formed with a single rotary member driven by a simplified drive mechanism coupled to the primary drive of the forage harvester to which the header is mounted. A horizontal drive shaft transfers the rotational power laterally to a gear box. The vertical output shaft from the gearbox has a first drive sprocket mounted thereon to connect directly with a drive chain fixed to the crop transfer disks, and a second drive sprocket mounted thereon and coupled to a drive chain entrained around a driven sprocket on the cutting disk to provide a drive speed differential with respect to the crop transfer disks. The crop guides are formed with rearwardly angled transfer arms cooperable with sweeper members on the crop transfer disk to direct the severed crop into engagement with the transfer disks for feeding into the forage harvester.

A corn harvester includes a first stalk roll having a plurality of first blades circumferentially spaced apart by a first angle. A second stalk roll has a plurality of second blades circumferentially spaced apart by a second angle. The first and second stalk rolls are rotatable about parallel first and second axes that are separated by a centerline therebetween. In an operational state when a tip of one first blade is aligned with the centerline, a tip of one second blade is angularly offset from the centerline by a third angle. The third angle is less than 45% of the second angle. The one first blade forms a cross section perpendicular to the first axis having an altitude extending from the tip toward the first axis along a first blade altitude. The cross section of the one first blade is asymmetric about the first blade altitude.

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.

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 maize header (2) comprising multiple mowing and infeed units (10) and comprising feeding drums (12) and turning drums (14, 15) arranged behind the mowing and infeed units (10), in the working position a feeding drum (12) is behind the two central mowing and infeed units (10a) and a first turning drum (14) is behind a transfer region between the central mowing and infeed units (10a) and a first lateral mowing and infeed unit (10b) that is laterally next to it, and to transfer the maize header (2) between the two positions, the mowing and infeed units (10) pivot relative to one another about axes (16) so the first lateral mowing and infeed units (10b) and one of the first turning drums (14) is pivotable relative to the adjoining central mowing and infeed unit (10a), so that, in the transport position, a frustoconical envelope (14a) of the respective first turning drum (14) is completely inside a permissible transport width of the maize header (2).

This is the assembly of the snout of corn headers where said snout is fixed to an end bearing (R) that allows the roller to maintain its rotating condition with respect to its own shaft, wherein said bearing (R) is fixed to an arm support (10) for its arrangement linked to the chassis of the machine. From the inner ring of the end bearing (R), a shaft (14) projects outwards to be associated with a ball joint (15) that is housed in a cavity that is defined between said support arm (10) and the internal face of an end cap (12) that is fixed by threading to the same support (10). The support arm (10) includes a transverse conduit (18) that extends to the internal threaded section through which the threaded cap (12) runs, and in said transverse conduit (18) there is a grub screw (16) that pushes, displacing a locking block (17). It is contemplated that the shaft that projects outward from the inner ring of the bearing may be a smooth shaft, a splined shaft, or may have a surface shape for coupling the internal cylindrical surface of the ball joint.

A self-propelled forage harvester is disclosed. The self-propelled harvester includes a mounting device having a feeder for harvested material and an adapter unit that is detachably arranged on the mounting device. The adapter unit is configured to mount and adapt an attachment designed for a combine harvester, with the adapter unit comprising a control and regulating module that is configured to perform control and regulating functions specific to the combine harvester for setting operating parameters of the mounted attachment.
