Abstract
A planting unit for a seeding machine having a seed meter with a metering member that moves seed sequentially along a first path to a release position at which the seed is moving in a first direction and a delivery system adapted to take seed from the metering member at the release position and control movement of the seed from the seed meter to a discharge location adjacent a seed furrow formed in soil beneath the seeding machine. The delivery system, at the release position, moves seed in a second direction along a second path. A blocking member located adjacent the first path immediately preceding the release position prevents movement of the seed in the second direction until the seed has passed the blocking member.
