    Abstract: A sectional control device controls the flow of particulate material from a meter assembly to a primary manifold of an air seeding system. The sectional control device includes a plate assembly having particulate openings extending between the meter assembly and the primary manifold and a shut-off mechanism configured to control the flow of the particulate material through the particulate openings. The shut-off mechanism includes a gate configured to slide between an open position, where particulate material can flow through the particulate opening, and a closed position, where particulate material is prevented from flowing through the particulate opening. The shut-off mechanism also includes an actuator configured to drive the gate between the open position and the closed position.
