Abstract
An agricultural seed planter and seed meter therefore, wherein the seed meter includes a rotary vacuum drum disposed within a stationary housing to entrain individual seeds on an annular circumferential periphery of the drum. As the entrained seeds rotate with the drum the seeds are singulated before being released from said vacuum drum. The seed metering and dispensing device is adapted to be mounted below the seed hopper to discharge the seeds into a seed tube as is conventional, or alternatively the seed metering and dispensing device is preferably adapted for mounting just above the soil surface and between the furrow opening assembly and furrow closing wheel assembly of a conventional agricultural planter such that the seeds are deposited directly into the seed furrow.
