<p>The plough has a cultivation trestle (2) with upper and lower linkage pivot points (5, 6) for attachment of upper and lower linkages fastened to a tractor. One of the upper and lower linkage pivot points is movably supported by a pivot point support device (9) against the trestle. A preloading device (10) is provided in a loading position for preloading of the pivot point (5) against the trestle, in which a driving force is induced in a lowered operating position of the plough at the upper linkage. A plough rear end is unloaded in the lowered operating position of the plough.</p> |
