The invention relates to a soil tilling process and to an equipment specially designed for applying the same. According to the invention, the process consists in that the step of breaking up the dislocated soil layer takes place concomitantly with the steps of haulage, tensioning and breaking, followed by an overturning at 180 degree , all the removed fragments following straight trajectories parallel to the working direction. According to the invention, the equipment comprises a ploughshare (2) located perpendicular to the movement direction and inclined under an angle (alpha) in relation to the furrow bottom, followed by a pair of rotors (6 and 7) located horizontally, the axes of said rotors being located in a common transverse vertical plane, and by a bar (16) for supporting and overturning the fragments from the dislocated layer, said bar being positioned at a certain distance from the axis of the lower rotor (6), so that the centre of gravity of the overturned soil fragment is beyond this bar. |
