Seed drill with a frame, a supply container, seed coulters having at least two separate inlets and outlets for two different materials, and depth-guide and pressure rollers arranged respectively behind the seed coulters, one material being fed to the front outlet and the other material to the rear outlet, each in adjustable quantities, via separate guides within the seed coulters, in order to be introduced into the ground, the outlets being at a distance from one another, as seen in the direction of travel, and a narrow tear-open body for tearing open the ground and for drawing a sowing furrow being arranged respectively on the side of the seed coulter facing the direction of travel. To achieve a reliable separate depositing of two materials, such as seed and fertiliser, even on heavy ground in the zero-tillage method, a widening body (41) projecting downwards into the sowing furrow is arranged respectively in the region of the rear outlet (30) of the respective seed coulter (1), the widening body (41) is at least somewhat wider than the tear-open body (25), and the lower end of the widening body (41) terminates higher than the lower tip (31) of the tear-open body (25). <IMAGE> |
