Abstract
System for controlling wing tool bars of an agricultural implement are provided. One implement includes a tool bar assembly having a central tool bar and a first wing tool bar rotatably coupled to an end of the central tool bar. The implement also includes a first actuator coupled to the first wing tool bar and to the central tool bar, and configured to raise and lower the first wing tool bar. The implement includes a solenoid controlled valve fluidly coupled to the first actuator. The implement also includes a switch electrically coupled to the valve. The switch measures an angle of the first wing tool bar relative to the central tool bar and is configured to transition the valve between a first and a second position based on an angle of the first wing tool bar relative to the central tool bar.
