ABSTRACT:
A planter, in certain embodiments, includes a structural air manifold. The planter may include a hollow structural member configured to bear and/or distribute static and dynamic loads of the planter. The structural member may include a hollow interior having a first port and a second port. A plurality of individual planting units and a fan may be mounted to the structural member and coupled to the hollow interior at the first and second ports, respectively, via a conduit. The hollow interior may provide a path for forced airflow between the first and second ports to enable pneumatic operation of a feature of the agricultural seed planter. Further, each planting unit may include a seed meter pneumatically coupled to the fan. An orifice may be disposed in the first or second port to restrict the airflow through the port and to the seed meter.
