Abstract:
1. An agricultural implement, comprising: a tool bar assembly comprising a central tool bar and a first wing tool bar rotatably coupled to a first end of the central tool bar; 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 relative to the central tool bar; a solenoid controlled valve fluidly coupled to the first actuator, wherein the solenoid controlled valve comprises a first position configured to enable fluid flow to the first actuator to raise the first wing tool bar relative to the central tool bar, and a second position configured to block fluid flow to the first actuator; and a switch electrically coupled to the solenoid controlled valve, wherein the switch is configured to measure an angle of the first wing tool bar relative to the central tool bar and to instruct the solenoid controlled valve to transition between the first and second positions based on the angle of the first wing tool bar relative to the central tool bar.
