Abstract
A system and method for regulating dispensation of seeds, fertilizer or other items. The system comprises a hopper, at least first and second movable metering plates, and an agitator assembly. Movement of the first and second movable metering plates in first and second directions, respectively, that are opposite one another increases a size of a plurality of output holes defined by interleaved portions of the metering plates, whereas movement of the first and second movable metering plates in the second and first directions, respectively, decreases the size of the output holes. An adjustable control handle can be moved to simultaneously move the first and second movable metering plates to adjust the size of the output holes. Each agitator remains in alignment with a center of a respective output hole regardless of a decrease or increase in the size of the output holes, resulting in more efficient dispensation.
