A seed meter with a flat seed disk with seed apertures on the peripheral edge of the disk results is provided. The seed pick-up on the disk edge enables a more predictable seed trajectory thereby improving the accuracy of seed spacing. With seed pick-up on the disk periphery, the seed reservoir in the meter housing is located rearward of the disk as opposed to the side of the disk, resulting in a narrowing of the meter housing, making it easier to package two meters close together for twin row planting or to lower the meter in the row unit, reducing the seed drop distance. With improved seed placement accuracy, the planter travel speed can be increased. Further efficiency is gained by a vacuum clean-out of the seed meters, reducing the time required to change seed type or variety.
