A method for operating a root crop conveying machine is provided, as well as a root crop conveying machine. Sensor data are recorded by at least one optical sensor. The optical sensor is directed to a measurement region of a flow of harvested material conveyed by at least one conveying element in a conveying direction. On the basis of the sensor data, mass data characterizing at least a mass of at least a part of the harvested material are calculated by an evaluation device. Yield data are calculated and provided by the evaluation device at least on the basis of the mass data. The yield data reflect at least the mass and/or a value calculated on the basis of the mass.

A method of detecting a potato virus in a crop image depicting at least one potato plant includes storing the crop image in a memory, identifying a first region of the crop image depicting potato plant leaves, identifying a plurality of edges within the first region, determining whether an image segment of the crop image within the first region satisfies one or more leaf creasing criteria symptomatic of leaf creasing caused by the virus based on the edges that are located within the image segment, determining whether the image segment satisfies one or more color criteria symptomatic of discoloration caused by the virus, and determining whether the segment displays symptoms of potato virus based on whether the image segment satisfies one or more of the leaf creasing criteria and the color criteria. A system and computer readable medium are also disclosed.

Machine for harvesting roots planted in the ground and aligned in rows, comprising a unit (36) for horizontally cutting the head of the roots, said unit having a means for automatically adjusting the level of its cutting blade depending on the level of this head, and being followed by a harvesting unit (48) that hollows out the earth beneath the roots at a relative height beneath the cutting level, characterized in that it has a means for detecting the height of the top of the root e, and a means for adjusting the relative height of the harvesting unit (48) with respect to the cutting level, depending on this height.

A method is provided for controlling the operation of a machine for harvesting root crop. At least one optical image-capturing unit captures at least one test image of harvested material comprising root crop which is moved along relative to a machine frame by means of at least one conveyor element. A conveying speed of the conveyor element is set on the basis of a test data set which is generated using the test image or formed by means of the latter. An evaluation device generates, on the basis of the test data set, a conveying speed signal, independent of a speed of the harvested material, for setting the conveying speed.

A folding rear cross system for a harvesting device having a harvesting direction and a discharge includes first and second substantially linearly aligned reversible endless belt sections, positioned near the discharge and oriented transverse to the harvesting direction. Each belt section has an inboard end disposed in overlapping relationship with the inboard end of the other. A lifting device is attached to selectively lift and lower the first and second reversible endless belt sections to reverse the overlapping relationship.
