Abstract
A pneumatically powered seed delivery system for an agricultural planter includes an air lock between a main seed hopper and the forced air delivery system. The air lock accurately meters the seed and isolates the interior of the seed hopper from the forced air delivery system. Seed is delivered to individual planter row units, each including an air horn having a buffer reservoir for storing and feeding seed to the associated seed meter under controlled conditions, and a seed routing conduit for carrying seed not deposited in a given seed meter to the other row units downline.
