In a drill, adequately formed delivery tubes, possibly equipped with guide plates, lead to drill coulters 10, which are triangular and turned forwards in the direction of driving, and which are provided with spreading means 12. By said spreading means 12 being placed in a sloping position relative to the lower side of the coulter 10 or to the direction of driving, and the upper side preferably being formed partially parabolic, an improvement of the spreading action of the coulter 10 is obtained. <IMAGE> |
