FIELD: agriculture .
SUBSTANCE: group of inventions relates to agriculture and can be used for prompt perception of altering harvesting conditions and efficient adjustment of performance parametres of grain combine operating elements. The grain combine is equipped with at least one device for withdrawing masses going from a screen with the device being fitted by at least one sensor to define the flow going from the screen. Signals for the masses going from the screen are generated by at least one sensor and are used to adjust one or more performance parametres of at least one operating element. The above signals are the signals stating the mass amount going from the screen and grain content in the mass.
EFFECT: ensuring prompt and effective response to altering conditions of cereal crop harvesting.
