Abstract
A particulate matter or seed dispensing system for an agricultural implement having a mobile frame with a plurality of row units mounted to the frame. The seed dispensing system includes an upright storage hopper that is adapted to be carried by the frame and has the capacity for holding a large quantity of particulate matter such as seed. A bin is adapted to be carried on each row unit for holding a quantity of particulate matter or seed. Notably, each bin holds substantially less than the quantity of particulate matter adapted to be held in the storage hopper. A metering unit is adapted to be arranged on each row unit proximate a furrow opener of the row unit. The metering unit is arranged in material receiving relation relative to a respective bin on each row unit. The dispensing system of the present invention further includes an apparatus for delivering particulate matter from the hopper individually to each bin as a function of the quantity of particulate matter or seed material in the bins. A method of dispensing seed material from a planter, grain drill or the like is also disclosed.
