摘要
An agricultural seeder has furrow opener assemblies spaced along a width of the implement frame. Each furrow opener assembly has an opener arm pivotally attached to the implement frame, and a furrow opener attached to the opener arm. A product delivery system delivers agricultural products to the furrow opener assemblies, and a product control controls the product delivery system such that agricultural products are delivered only to active furrow opener assemblies. A bias force system is operative, when activated in a transport mode, to exert an upward bias force on the active and idle furrow opener assemblies, and operative, when activated in an operating mode, to exert a downward bias force on the active furrow opener assemblies, and to exert substantially no force on the idle furrow opener assemblies.
