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 including a plurality of transversely spaced row units engageable with the ground for the planting of seeds therein, the improvement comprising: a nurse mechanism associated with each said tank to communicate with the corresponding said discharge opening and said corresponding conduit to receive seeds from said tank and convey said seeds to said planting mechanism; a control mechanism operatively associated with said nurse mechanisms to control the flow of seeds from each of said tanks to all of said row units engaged with the ground for the planting of said seeds therein; wherein said control mechanism permits the flow of seeds from only one of said nurse mechanisms at a time, a receiver header operatively coupled with said conduit from both said nurse mechanisms to deliver seeds to more than one row unit; and a receiver with each said row unit coupled with one of said receiver headers, said receiver being formed with two compartments to hold seed product from the respective tanks, said receiver header being operable to convey seeds from the respective said tanks to the corresponding compartments.
