FIELD: agriculture.
SUBSTANCE: mounted reversible plough contains a hinged element for attachment to a tractor, an inversion device pivotally attached to the hinged element relative to the inversion axis, an inversion actuator between the hinged element and the inversion device, a frame on which a double row of ploughing elements is installed, which are alternately activated in accordance with the position inversion device relative to the inversion axis. The frame is attached to the inversion device by means of an articulated arm and a frame linearization actuator. In order to change the working width between successive arable elements, an actuator is provided for adjusting the working width of the arable elements. The articulated arm at its first end is pivotally attached to the frame relative to the linearization axis of the frame, and at its second opposite end is pivotally attached to the inversion device relative to the articulation axis. The linearization actuator is driven by a pressurized fluid, the flow of which can be stopped by a valve to limit the straightening of the frame, which is controlled by the linearization actuator when the frame is driven to rotate about the inversion axis. The valve is actuated according to the relative angular position of the pivot arm with respect to the inversion axis.
EFFECT: simplified design with a well-protected and efficient valve control circuit, eliminating assembly play.
