In a mounted plough having a towing or mounting part couplable to a three-point linkage of a tractor by means of a coupler, the gear cooperating with the coupler and with the plough frame consists of two lockable links acting independently of one another. The first of these links is articulated at the adjusting tow point of the plough frame and the second at its control tow point. For the freely oscillating adjustment of the horizontal forces, the second link has an arrangement, movable at a parallel to acute angle or in a semicircular arc and lockable, for the purpose of changing its effective length.
