In seeding apparatus a plurality of discs for cutting slits in the ground are carried by arm assemblies which are spaced transversely across the apparatus. The arm assemblies are rigidly connected together in pairs to form separate units, and each arm assembly comprises an arm which is cranked at an intermediate point in its length with each arm carrying a pair of discs which are staggered longitudinally and transversely, being journalled for rotation on inner and outer arm portions on opposite sides of the crank. A pair of ground compacting rollers carried by the unit and journalled for rotation about axles normal to the longitudinal axis of the unit are each adapted to close slits cut in the ground by the two discs carried by each respective arm. |
