摘要：
A sectional control device (12) controls the flow of particulate material from a meter (28) assembly to a primary manifold (24) of an air seeding system. The sectional control device (12) includes a plate assembly (56) having particulate openings (36A, 36C, 36) extending between the meter (28) assembly and the primary manifold (24) and a shut-off mechanism configured to control the flow of the particulate material through the particulate openings (36A, 36C, 36). The shut-off mechanism includes a gate (44A, 44) configured to slide between an open position, where particulate material can flow through the particulate opening (36, 38), and a closed position, where particulate material is prevented from flowing through the particulate opening (36, 38). The shut-off mechanism also includes an actuator (40A, 40) configured to drive the gate (44A, 44) between the open position and the closed position.
