The method and apparatus for continuous turn-over of soil in accordance with the invention are characterized in that the turn-over of soil takes place in a system including a rotor, the direction of rotation of which is opposite to the wheels of a vehicle drawing the rotor, and symmetrically-shaped plough units cooperating with the rotor in such a way that the pikes of the bows of the rotating rotor engage the soil, which has been lifted by the plough unit, from beneath and from behind, as seen in the direction of movement of the apparatus. The flow of soil thus lifted up is divided up into transverse pieces, which are turned and deposited behind the apparatus. During this process the rotary movement of the rotor is independent of the control of the displacement movement of the apparatus. Also, the compactness of the soil material may be levelled out to the required degree through preparatory working. Reference FIG. 1.
