Abstract
A nurse distribution system provides dual capabilities for planting different seed varieties from a single planting mechanism. The air cart carries two tanks in which different seed varieties can be placed. The nurse mechanism selectively distributes seed from one tank to the on-row singulation meters, yet can switch to the seed in the second tank to correspond to different soil conditions encountered by the planting mechanism. The planting mechanism carries a first line from the first tank to the nurse receiver and a parallel second line from the second tank to the same nurse receiver. By keeping the nurse receiver as small as possible, thus having a small seed reservoir, the seed variety selection can be switched from one tank to the other in an effective manner.
