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.

A material introduction lock for a distribution machine for pneumatically conveying granular material in a conveying line adjoining a material introduction lock includes: an air inlet, a material conveying element, and a material infeed element, where a pneumatic conveying flow is supplied to the material conveying element via the air inlet, and the material infeed element is arranged between the material conveying element and the conveying line so that the granular material in the conveying line supplied via the material infeed element is conveyed in the conveying line by the pneumatic conveying flow supplied by the material conveying element. Further, the material infeed element includes a rinsing nozzle element which is connected to the air inlet and creates a film of air that sheathes the material infeed element from the inside, and the rinsing nozzle element is configured to reduce contact between the granular material and the material infeed element.
