Abstract of the Disclosure A seed-spacing drill comprises a discharge disc, which constitutes the rear wall of a seed box and has suction openings for sucking the grains and communicates with a suction fan and discharges the grains of seed through a discharge opening of the seed box out of the latter. To ensure that only a single grain will be discharged at a time, the discharge disc consists of two parts, namely, a disc body, which com- municates with the suction fan, and a disc blade, which contacts the disc body on the side facing the supply of seeds in the seed box. One of said parts is statio- nary and has a guide slot, which defines the discharge path. The other part is rotatably mounted and has peri- pherally spaced apart entraining slots, each of which extends throughout the radial extent of the guide slot.
