FIELD: agricultural industry.
SUBSTANCE: present group of inventions refers to the agricultural machinery industry and may be used in reaping threshers. The method provided in the present invention involves setting optimum rotation speed of drum beater and concave gap depending on the delivery rate required by given conditions. Deviation of actual delivery rate from the set value is automatically detected and at least one of the aforesaid values is adjusted with the actual value. The reaping thresher comprises a drum beater, control unit for setting optimum rotation speed of drum beater and concave gap. The said control unit incorporates a drum beater rotation speed control device which adjusts at least one of the aforesaid parameters set for the drum beater with the actual delivery rate.
EFFECT: quick automatic response of the beater drum to any change in delivery rate.
