AIR SEEDER PNEUMATIC CONTROL SYSTEM

A seeder assembly for placing a commodity in underlying soil, where the seeder has a chassis member with at least one ground engaging mechanism configured to contact an underlying ground, a row unit coupled to the chassis, a third tank coupled to the chassis and to the row unit, a second tank coupled to both the chassis and the third tank, and a first tank coupled to the second tank. The first tank may be a commodity cart. The first tank may have a metering system and a pneumatic distribution system that distributes the material throughout the seeder assembly. The second tank may include one or more sensors and a status indicator. The second tank may calibrate the metering system, using sensors or by using a load cell.
