A regulator (25) for a nurse inductor mechanism (20) on an agricultural seeding implement controls the rate of entrainment of seeds into the stream of air directed into the nurse inductor mechanism. The regulator (25) includes a pivoted gate (29) mounted at the discharge opening of the seed reservoir of the nurse induction unit (20) to control the flow of seed particles into a pile for engagement with the stream of air (13) directed thereto. An actuation lever (28), positioned externally of the nurse inductor housing so as to not interfere with the sealed relationship between the divider walls (32) of the distribution apparatus and the housing, is selectively manipulable to move the pivoted gate between closed and opened positions. Once the pivoted gate is moved into the closed position, the flow of seed particles into the distribution apparatus is halted, but the full flow of air can still move through the distribution apparatus and seed distribution tubes to effect a clean-out of the nurse induction unit. <IMAGE> |
