It is provided with a double pilot operated check valve which provides leakage control on the cylinder in any position. The reversal of the cylinder is controlled by a pressure compensated relief valve set to exactly in the dead head point of the plough, generating more power ad speed. It can be assembled on heavy and unbalanced ploughs with cylinders with the following internal diamters: 40/50, 60/80, 80/100, 100/110, 110/130 mm.
