Improvements in the hydraulic elevators for farming implements, which are essentially characterized by the interposition of new elements in the structuring of the elevators, aimed at establishing a free circuit, of constant rhythm for the circulation of the oil, in avoidance of overheating, by means of of a combined set of concentric double valves equipped in addition with a key element, such as a latch or latch that, under the impulse of an eccentric, opens one of the valves at the appropriate time, to produce the smooth exit or evacuation of excess oil, which ends its course in the block carter.
