The present invention relates to a self-propelled
forage harvester (1) comprising a height-adjustable header (4) for receiving
crop (2), working units (20) for
processing the received
crop (2), an unloading device (15) for discharging the processed
crop (2), a camera
system (16) for capturing images (41) of a crop flow (21) passing through the
forage harvester (1), an
image evaluation device (27) for evaluating the images (41), and a driver assistance
system (17) for controlling the header (4), the working units (20), and the unloading device (15), wherein the driver assistance
system (17) has a memory (40) for storing data and a computing device (39) for
processing the data stored in the memory (40), wherein the
image evaluation device (27) together with the driver assistance system (17),The front attachment (4) and the working units (20) form an automatic setting system, in that the
image evaluation device (27) is configured to continuously analyze the images (41) of the crop flow (21) for the proportion of, in particular inorganic, impurities contained in the crop flow (21) by means of a
machine learning
algorithm and to transmit a derived degree of
contamination (DC) to the driver assistance system (17), which autonomously and continuously adapts a setting of the front attachment (4) and / or at least one of the working units (20) depending on the degree of
contamination (DC).
