ABSTRACT:
A seeding machine is provided with a frame comprising a center frame section and left and right wing frame sections. The frame has a planting configuration and a transport configuration. The center frame section and the left and right wing frame sections each have a hollow toolbar forming a pneumatic manifold. Individual planting units are mounted to the toolbars. The pneumatic manifold of the center frame section is automatically pneumatically coupled to each of the left and right wing frame sections by a resilient bell that forms a pneumatic path between the center frame section and the left and right wing frame sections when the frame is in its planting configuration. The pneumatic manifolds are pneumatically coupled to pneumatic seed meters on the planting units by air hoses.
