Abstract
A seeding machine is provided with banks of individual seed hoppers for directing seed to auxiliary seed hoppers located on individual planting units. The individual seed hoppers of each bank are provided with adjoining walls. The adjoining walls have notches so that seed in one individual seed hopper can flow into an adjoining individual seed hopper. A portion of the planting units can be disabled by placing them in a non-working position. The individual seed hoppers supplying seed to the disabled planting units are provided with removable baffles. Each removable baffle is provided with a downwardly extending leg that cooperates with the notches to prevent seed in an active individual hopper from entering an inactive individual hopper.
