Seed drill, with a frame and with seed coulters which are arranged vertically movably thereon and which are additionally connected individually to the frame via resilient elements which also act on them in the direction of the ground and the tension of which can be varied by means of a central adjusting device, there being arranged on the central adjusting device at least one resilient compensating element counteracting the resilient elements engaging on the seed coulters. In order to improve the seed drill according to the main patent so that, even under varying ground conditions, the coulter pressure is changed automatically in such a way that the desired depositing depth of the seed is always maintained, provision is made for arranging on the seed drill a measuring device (7) for recording the coulter draught (T) and a regulating device (25) connected to this measuring device (7), and for connecting this regulating device (25) to the central adjusting device (6). <IMAGE>
