Abstract: A method for increasing the load on driving rear wheels (KB, KP) of a tractor during soil cultivation with a farm implement (2), attached to a three-point linkage (1) of the tractor. A vertical position of the attached implement (2, 20) is adjusted relative to the tractor by a position of the arms (4) of a lifting device and by adjustment of the length of the upper link (13) of the three-point linkage (1) of the tractor. After adjusting the length of the upper link (13), the axial force acting/induced in the upper link (13) is determined and during travel of the tractor is continuously monitored and automatically maintained at the adjusted value. Also the adjusted vertical position of the implement (2) attached to the tractor is continuously monitored (2) and is automatically maintained at the adjusted value, thereby maintaining the vertical position of the attached implement (3) in this regulation and thus also constant ploughing depth.

Abstract: The invention relates to a method for increasing the load on driving rear wheels (KB, KP) of a tractor during soil cultivation with a farm implement (2), in particular with a plough (20), attached to a three-point linkage (1) of the tractor, in which the vertical position of the attached implement (2, 20) is adjusted relative to the tractor by means of the position of the arms (4) of a lifting device and the length of the upper link (13) of the three-point linkage (1) of the tractor is adjusted.
