The invention relates to a plough which is used by actuating a thrust movement from a tractor vehicle with one arm lowered and with the other one raised, then it is turned and returns to the same furrow with the arms in the opposite position. The said plough is constituted by a metal chassis, wheel sets, a vertical tripod or turret, a receptacle for electrically operated valves, turning means, fluid transmission lines, hydraulic cylinders and dispensers. |

1. Hydraulic plough actuated by tractor vehicle thrust, constituted by a horizontal metal chassis (1) in the form of a cross, supported on at least four wheel sets (2), wherein each wheel set has two twin wheels which rotate around 360° and are adapted to the terrain by their beam, uniformly distributed for the stability of the assembly by means of two transverse shafts, one of them in the front area and the other in the relatively central area, with a vertical tripod or turret (3) in order to hitch up to the front linkage of the tractor, and, in its base, a receptacle for electrically operated valves (4) and controlled turning means for the said tractor vehicle, with fluid transmission lines (5) which are connected at one end to the vehicle, and at the other end to the receptacle for electrically operated valves, and then in turn to the hydraulic cylinders, characterized in that it has four cylinders (6) for the control of dispensers, two cylinders (7) to control the depth of ploughing and raising of the plough, two cylinders (8) for the gauge widening of the central wheels and four cylinders (9) which raise the plough for travel on a road. |
