Abstract:
1. In an agricultural planting implement having a frame adapted for movement over the ground, a hopper supported on said frame for carrying a supply of seed, said hopper having a lower portion including a discharge opening through which seed particles pass to exit said hopper; a flow mechanism for creating a flow of air through a conduit; and a remote planting mechanism engageable with the ground for the planting of seeds therein, the improvement comprising: a nurse mechanism supported on said hopper to communicate with said discharge opening and said conduit to receive seeds from said hopper and intercept the flow of air coming from said flow mechanism and create an air stream through said nurse mechanism, said nurse mechanism entraining seeds with said air stream for conveyance through a discharge tube in flow communication with said nurse mechanism; a receiver at said planting mechanism in flow communication with said discharge tube to receive seeds entrained in said air stream, said receiver accumulating a supply of seeds for utilization by said planting mechanism; a receiver header operatively coupled with said discharge tube and said receiver to direct seeds entrained in said air stream toward said receiver; and at least one movable baffle disposed internally of said receiver header and having first and second outlets associated with first and second singulation meters, the baffle being selectively movable between an open position directing seed delivery through said first and second outlets and a second position blocking seed delivery from at least one of said outlets.
