ABSTRACT OF THE DISCLOSURE An hydraulic ram is situated between the tillage tool and the frame and is normally fully extended and acts as a rigid link. The ram has a predetermined and adjustable pressure so that if an obstruction is encountered by the tool, it only re- tracts when the preset pressure is exceeded and then returns to the fully extended position as soon as the obstruction is passed. It can be used on machines such as discers, hoe drills, press drills or any ground working implement which includes tillage tools which are pivoted to the frame and which do not. engage the ground by raising and lowering the frame.
