Abstract: An agricultural harvesting machine has a control arrangement including an optical sensor device for recording image series of a continuous main crop stream, an evaluation device for ascertaining a portion of damaged grain, a portion of non-grain in the main crop stream or both, on the basis of an image analysis of the recorded image series and a visualization device for displaying the portion of damaged grain and/or the portion of non-grain. The control arrangement cyclically records image series of the continuous main crop stream and, within a predetermined processing time after an image series has been recorded, displays a current portion of damaged grain, a current portion of non-grain or both, based on the image series.

Abstract: A cleaning device for cleaning a grate bar comprising a pair of tongs having two limbs held in an opened position, and being squeezable into a working position by hand-applied force. A holding element at a free end of each limb. The holding elements are disposed such that: (1) when the tongs are in the opened position, there is no overlap between the holding elements, which are separated by a distance that is larger than the diameter of a grate bar, and the free ends are separated by a distance which is smaller than the distance between adjacent grate bars; and (2) when the tongs are in the working position, the holding elements overlap. The cleaning device includes, at the free ends of the limbs, a cleaning element in the form of at least one flexible cleaning cable which can be at least partially wrapped around the grate bar.
