Abstract
A seeding machine comprising a transversely extending main frame and left and right transversely extending wing frames. The main frame and the wing frames are provided with a plurality of planting units. Left and right main seed hoppers are mounted to the main frame. The left and right main seed hoppers are transversely separated from one another by a longitudinally extending gap located along the longitudinal centerline of the seeding machine. A pneumatic seed on demand delivery system automatically directs seed from the left and right main seed hoppers to the planting units. A walkway is positioned in the gap between the left and right main seed hoppers to facilitate operator access to the lids of the main seed hoppers.
