Earth-moving vehicle with device for configuration of profile for circulation on road

A work vehicle comprising:

• an operating arm comprising a terminal stretch and an intermediate stretch and a hydraulic actuator for effecting relative movement between the terminal stretch and the intermediate stretch;
• a main valve hydraulically coupled to the actuator for controlling fluid flow to the actuator;
• a pilot valve hydraulically coupled to the main valve, wherein the pilot valve is manipulated by an operator and controls fluid flow to the main valve;
• a solenoid valve hydraulically coupled to the pilot valve, a reservoir and a pump, the solenoid valve being actuatable to one of a first position and a second position, the first position coupling the pilot valve to the reservoir and the second position coupling the pilot valve to the pump;
• and
• an electrical circuit coupled to the solenoid valve, the electrical circuit comprising a relay, a manual switch actuatable by the operator and a position-sensor switch, the relay and manual switch being disposed in series, wherein the position-sensor switch is closed when a pre-defined position of the operating arm is sensed by a position sensor, which is electrically coupled to the position-sensor switch,
• wherein the relay actuates the solenoid valve to the first position when the manual switch is actuated by the operator and the position-sensor switch is closed.
