APPARATUS FOR REMOTE ADJUSTMENT OF THE STOP MECHANISM FOR CONTROLLING CONTRACTION OF A HYDRAULIC CYLINDER

摘要

A mechanism is disclosed utilizing flexible sheath and a cable is used in remote adjustment of the depth of penetration of the ground by earth working tools such as sweeps of a cultivator. The cable control is used to adjust the distance a piston rod of a power cylinder has to travel before the flow of hydraulic fluid is blocked by a control valve actuated by engagement of an abutment member and a stop plate.
