The agricultural drilling machine has a depth guide and a pressure roller (7) with a disc (21) that is formed on a rear active arm (22). The rotation direction (23) of the roller is built bent and the outer approximately reduced. The arm may have pieces that are bent inwards at an angle of between 70 and 100 degrees especially 85 to 95 degrees. The end of the arm may have an L-shaped length of between 5 and 9 cm long and preferably 7cm long. The end of the arm may also be parallel with the upper ground surface.
