The applied section of a threshing unit for use in an agricultural harvester comprises a rotary element, at least one concave, a hydraulic supporting system of the concave, a controller for regulating the pressure in said hydraulic support system of the concave and at least one position sensor. Said section of the threshing unit is supplemented with at least one pressure sensor for transmitting a signal, which represents the pressure in the stated to marked hydraulic supporting system of the concave, into said controller. Said controller maintains the stated pressure at the preset value, until the mentioned distance exceeds the preset distance, and then the mentioned pressure is increased, to prevent from the further deviation of the mentioned concave from said rotary element. The applied agricultural harvesting machine comprises a frame and a section of the threshing unit which rests on the stated frame. |
