Abstract
A nurse receiver header for an agricultural planting implement is cooperable with a nurse mechanism that conveys seeds entrained in an air stream from a central hopper. A receiver is positioned at the planting mechanism to receive the seeds entrained in the air stream and accumulate a supply of seeds for utilization by the associated planting mechanism. The receiver header includes a plurality of legs and a rotatable baffle positioned internally at an uppermost position of at least one leg of the receiver header. The baffle is pivoted by an external lever that is positioned in the same orientation as the baffle to indicate the position of the baffle. The header can be placed in a closed configuration by positioning the baffle across the leg to be blocked. When in an open configuration, the baffle is positioned parallel to the leg and all of the legs of the header are open.
