A traction vehicle comprises a hydraulic system (5) as well as two bottom links (9) and at least one top link (10) for attaching a mounted implement (11). An adjusting device that extends in the direction of the longitudinal axis of the vehicle and comprises at least one hydraulic cylinder (8) or an electromotive adjusting device is associated with at least one of the bottom links (9). The invention makes available a control means and a mechanism for directing mounted implements and machines on traction machines and tractors with precision at right angles, along parallel lines, even in hilly terrain or on slopes and on straight or odd-shaped fields. This serves as a basis for automating agriculture as a whole.
