Abstract
An air seeder apparatus has a frame and a plurality of furrow opener assemblies spaced across a width of the frame at a narrow row spacing, and a plurality of bulk product containers and a bulk meter mounted on each, one of which dispenses seeds through a distribution network to a seed tube on each furrow opener assembly. A plurality of singulating meter is provided, each dispensing singulated seeds to the furrow opener on one of the furrow opener assemblies. During singulating operation seeds are delivered to the singulating furrow opener assemblies only by the singulating seed meter, and during conventional operation seeds are delivered to the singulating furrow opener assemblies only by the bulk meter. A lift system, when in a singulating mode, maintains idle conventional furrow opener assemblies in the transport position while moving singulating furrow opener assemblies between the operating position and the transport position.
