Abstract:
1. In an agricultural planting implement having a frame adapted for movement over the ground, a first tank supported on said frame for carrying a first supply of seed, a second tank supported on said frame for carrying a second supply of seed, each said tank having a lower portion including a discharge opening through which seed particles pass to exit said tank; a mechanism for creating a flow of air through a conduit associated with each said tank; and a remote planting mechanism engageable with the ground for the planting of seeds therein, the improvement comprising; a first nurse mechanism associated with said first tank and a second nurse mechanism associated with said second tank, each first and second nurse mechanism configured to communicate with the corresponding said discharge opening and said corresponding conduit to receive seeds from said first and second tanks, respectively, and convey said seeds toward said planting mechanism through one of a first plurality and a second plurality of primary nurse lines; and each of said first of primary nurse lines from said first nurse mechanism being connected via a first connect mechanism to an adapter having a plurality of distribution lines extending therefrom in communication with said planting mechanism, wherein each said adapter is configured to disconnect from each of said first plurality of connect mechanisms and connect to each of said second plurality of connect mechanisms so as to switch from delivering the first supply of seed via the first nurse mechanism from the first tank to delivering the second supply of seed via the second nurse mechanism from the second tank to the planting mechanism.
