Abstract: 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).

Abstract: An agricultural harvesting machine embodying a forage harvester includes a comminution assembly with a drum equipped with a plurality of knives. The drum is set into rotation opposite a stationary shear bar in order to comminute crop fed in a region of a cutting gap formed by knives and the shear bar during the harvesting operation. A device controls a rotational speed (n) of the drum at least during a maintenance procedure of the comminution assembly, depending on a property of the drum.

Abstract: A self-propelled agricultural harvesting machine such as a forage harvester includes a front harvesting attachment for picking up crop from a field as well as one or more working mechanisms for processing and conveying the crop. At least one functional device assigned to the harvesting machine can be adjusted with respect to one or more parameters for the purpose of adapting to different conditions of use. The machine includes a control device that operates in a field initial-cutting mode in order to specify at least one parameter setting for at least one of the functional devices so that the parameter setting the harvesting machine can be brought into a configuration that is suitable for the initial cutting of the field.

Abstract: An agricultural harvesting machine embodying a self-propelled forage harvester is equipped with a shredding assembly for the continuous shredding of crop conveyed as a crop stream through the shredding assembly and a recutter disposed downstream of the shredding assembly relative to the direction of crop flow that comprises at least one cutting element that is moveable into and out of the crop stream. A control device that is operated via actuation of an actuator assigned to the cutting element to move the cutting element out of an inactive position (P0) in which the cutting element is ineffective relative to the crop stream into at least one active position (P1) in which the cutting element extends into the crop stream effectively imposing a shredding effect on the crop.

Abstract: A method for controlling a transfer device (2) mounted pivotally on a harvesting machine (1) so that it can be pivoted about both a vertical axis (3) and a horizontal axis (4) is described. In this method the transfer device is automatically swung from an actual position (A) about the vertical axis (3) into another position above a supporting member (11) for the transfer device (2) mounted on the harvesting machine (1). The transfer device (2) is then automatically lowered into a street travel position on the supporting member (11) within an event-controlled street travel positioning procedure.

Abstract: A method and apparatus for determining the distance between an agricultural machine and a surface such as the ground, wherein at least one sensor contactlessly determines the distance between the sensor and the surface. The sensor uses electromagnetic waves to penetrate through the field vegetation. The sensor may be a radar, a microwave or a laser sensor. The electromagnetic wave is emitted in a vertical direction toward the ground and reflected back to the sensor. The determined distance is used for automatically maintaining a working height of a front attachment, such as a cutterbar.
