ABSTRACT:
The present device is adapted for use with conventional row planters which have two separate groups of planting devices thereon. The present invention permits each of the planting systems to be separately turned on or off. The planting selector is operated on a gear driven fulcrum bar that is connected at its opposite ends to two levers. Each lever has a fork on one end that engages the clutch mechanism for one of the two planter systems. The gear driven fulcrum bar is driven by an electric motor which is capable of driving the fulcrum bar in a first direction or which is capable of being reversed to drive the fulcrum bar in an opposite direction. The fulcrum bar has three positions. In the middle position, the device will allow the two separate clutches for the two separate planting systems to be engaged so as to activate both planting systems. The two other positions permit one of the planting systems to be deactuated and the other of the planting systems to be activated.
