The present invention lies in a three hopper bin air seeder. The contents of the central hopper bin are capable of being emptied into the rear hopper bin or the front hopper bin, or when central hopper bin ports are closed, the contents of the central hopper bin can be directed into a primary conveyance duct. The invention also employs a pair of blower fans and three pressurized ducts. By using flexible and moveable couplings, the contents of any two or three hopper bins can be combined into a single particulate stream. Similarly, three separate streams of material such as seed, fertilizer or granular herbicide can be directed to various soil working tools on a cultivator, or other seeding device.
