ABSTRACT:
An actuating system for a planting device. The actuating system has an electric motor that provides an actuating force for a seed shaft. A pneumatic acting member is connected to a source of compressed air through a valve and positioned to engage the electric motor to actuate the electric motor. The source of compressed air and electric motor can thus be connected to a controller that operates the source of compressed air and the electric motor in order to provide selective actuation to control planting of the planting device.
