Abstract
A seed metering system includes a seed tank including a seed tank outlet, and a number of row units. Each and every row unit of the number of row units comprises a singulating meter in selective communication with the seed tank outlet, a bypass conduit in selective communication with the seed tank outlet, and an outlet. The seed metering system further includes a volumetric metering system positioned upstream of the number of row units and operable to volumetrically meter the plurality of seeds. The seed metering system is operable in a first mode of operation in which the seed tank outlet communicates with each singulating meter via the volumetric metering system to singulate the plurality of seeds. The seed metering system is operable in a second mode of operation in which the seed tank outlet communicates with each bypass conduit via the volumetric metering system and seeds are not singulated.
