ABSTRACT:
A shut-off means for an air-actuated planter is disclosed, which includes a butterfly valve located within the air manifold of the planter unit, which is connected to a rotational means further connected to a solenoid. A power source is connected to the solenoid which, with the activation of a switch, causes current to flow to the solenoid, rotating the rotational means, and causing the butterfly valve to move within the air manifold. In this manner, air within the air manifold may be blocked at any point where the air valve is located, shutting off the air source to one or more planter units.
