A sowing machine has row units, where each of the row units includes tillage tools and a hydraulic cylinder which applies a coulter pressure upon the tillage tools that is adjustable by a pressure valve. Further, a sensor arrangement includes at least two sensors for producing an electrical signal in connection with a total pressure acting upon the tillage tools of each row unit. In addition, an open-loop or closed-loop control device is connected to the pressure valves and the sensor arrangement and configured to adjust the coulter pressure of each row unit individually and to adapt it on the basis of the electrical signals of the sensor arrangement. In order to create a sowing machine with individual coulter pressure control that is inexpensive to manufacture, a reduced number of sensors is advantageously employed by using a functional relationship.
