<p>A soil-tilling machine towed by a vehicle, comprising a chassis (1) bearing at least one drawbar (2) attached to the vehicle, means of lifting, a reference unit (4) and at least one plurality of soil-tilling tools (3) using a harrow pressure adjustable by means of the reference unit (4), the roller-type reference unit (4) rotating around an axis (YY'), the means of lifting the chassis (1) comprising at least one pair of wheels (5, 6) and being adapted to bring the chassis (1) from a tilling position in which the reference unit (4) is on the ground and in which the wheels (5, 6) are raised above the ground, to a transport position in which the reference unit (4) is raised above the ground and in which the wheels (5, 6) are on the ground. The axes (ZZ') of the wheels (5, 6) of the means of lifting are substantially orthogonal to the rotational axis (YY') of the reference unit (4), and the drawbar (2) is mounted movably on said chassis (2) between the tilling position in which it is substantially parallel to the rotational axes of the wheels and orthogonal to the rotational axis (YY') of the reference unit (4) and the transport position in which it is substantially perpendicular to the rotational axes (ZZ') of the wheels (5, 6).</p> |
