Abstract
A multiple variety planter has a direct vacuum system that allows for planting multiple varieties of seed while reducing occurrences of mis-planting events or planting inconsistencies such as multiples and skips by providing highly controllable seed meter vacuum performance characteristics that are controllable on a row-by-row basis. The direct vacuum system may include a vacuum unit at each row unit of the planter to apply a vacuum pressure to a seed meter at the row unit. Each vacuum unit may be individually and variably controlled to apply different vacuum pressures based on which seed variety is being planted with the respective seed meter at a given time.
