Abstract
A seed supply system for a multiple row sower comprises a main seed hopper connected to a plurality of sower units by seed supply ducts. The main hopper has a seed distributor that divides a supply of seed uniformly between the seed supply ducts as seed flows out by gravity. The hoppers of each sower unit are provided with partitions that can be moved up or down to adjust the seed volume contained within the hopper. The partitions can then be adjusted so that the volume of seed contained within a sower unit hopper and its associated seed duct is equal to the volumes of each other sower unit hopper and the associated seed duct. By equalizing the volumes in this way all hoppers will run out of seed essentially simultaneously.
