The invention relates to a seed-spacing drill, consisting of a cellular wheel which rotates about a horizontal axis and which is formed from a hollow cylinder closed on one side and has in its open edge, in a manner distributed over the circumference, cells each receiving one seed grain, and of a stationary cover wall which has the seed inlet and which surrounds the cellular wheel on the outside by means of an all-round axially projecting edge leaving only the seed outlet free, whilst within this edge is provided a cover ring which, during the rotation of the cellular wheel, prevents the seed grains from falling out of the cells towards the seed outlet, the said seed-spacing drill being characterised in that there is provided at the end of the seed outlet a cell cleaner which reaches close up to the outer circumference of the cellular wheel and which presses any seed grains or foreign bodies "S" caught in the cell out of the cell inwards.
