Abstract
A master/slave hydraulic system is disclosed for raising and lowering a farming implement such as a cultivator. The system is provided with a system of check valves and a pressure reducing valve arranged such as to avoid rebound in the cylinder system. The chatter in the system on lowering of the implement is avoided by providing means to utilize the pressure generated by the weight of the implement in combination with the pilot pressure from the lower line. The system disclosed also secures the locking of the pressure insidethe system to prevent leaking through the control valve to the tank of the supply/discharge system by way of check valves in each of the two supply/discharge lines.
