ABSTRACT:
The planting machine comprises a hopper having a bottom formed by a belt conveyor which extends outside the hopper. A tuber supply device supplies the tubers one by one from the conveyor to the furrow to be sown and comprises a collector cup mounted at the end of the conveyor which receives each tuber from the conveyor. A device responsive to the presence of a tuber in the cup stops the conveyor when the tuber is in the cup. Movable cups for taking up the tuber received in the collector cup drive the tuber into the furrow.
