Abstract

The plough is attached to the three-point linkage of a tractor. The lower link (16) is operated by the piston (18) of a hydraulic lifting jack. A control valve (21) is mounted on the upper link (20). The pressure feeler responds to the force transmitted by the upper link (20). The upper link (20) is formed for two sections which move elastically in relation to one another with the effect of the force transmitted, and the valve (21) is regulated by the relative movement of the two upper link sections. The first upper link section forms a casing (68) open on one side and closed on the other, divided into two compartments by a partition with a central hole, with a spring in each compartment.
