Split seed hoppers for seed on demand seeding machine

A seeding machine comprising:

• a drawbar defining a longitudinal centerline;
• a transversely extending main frame, the main frame is provided with a plurality of planting units, each planting unit comprises an auxiliary hopper for holding seed, a seed meter for metering seed contained in the auxiliary hopper and a furrow opener for forming a planting furrow into which seed metered by the seed meter is deposited;
• left and right main seed hoppers for holding seed are mounted to the main frame, the left and right main seed hoppers are transversely separated from one another by a gap along the longitudinal centerline, the gap is provided with a longitudinally extending walkway between the left and right main seed hoppers;
• a pneumatic seed on demand delivery system automatically directs seed from the left and right main seed hoppers to the auxiliary seed hoppers of the planting units as needed.
