Abstract:
A self-propelled agricultural harvesting machine comprising:a first attachment having a first working width for harvesting stalked crop standing in a field and a second attachment having a second working width for picking up cut crop lying on a field, wherein the first and second attachments are used alternatively; a processing device for chopping or processing the crop; an unloading device arranged downstream of the processing device and comprised substantially of a curved spout for picking up the crop from the processing device at a pick-up location and for transferring the crop to a drop location on a transport vehicle spaced at a distance from the pick-up location; a drive motor; and a control device configured to adjust an operating speed of the drive motor to an idle speed, a nominal speed, and a speed range below the nominal speed, wherein the drive motor, when the first attachment is used with the harvesting machine and the distance between the pick-up location and the drop location of the curved spout has a first length (L1), is operated in the range of the nominal speed and, when the second attachment is used with the harvesting machine and the distance between the pick-up location and the drop location of the curved spout has a second length (L2), is operated in a speed range reduced relative to the nominal speed, wherein the first working width is greater than the second working width and wherein the first length (L1) is greater than the second length (L2).
