ABSTRACT:
A soil cultivation implement comprising a frame adapted to be coupled to a drive means, and said frame supporting, one behind the other in the direction of travel, first cutting means for cutting the ground substantially vertically, second cutting means for dividing the ground substantially horizontally and lifting it in a rearward direction, and a substantially horizontal rotor. The rotor is provided with power means from said drive means and is adapted to be driven rotationally and provided with prongs for penetrating the surface of the ground. The prongs are disposed helically on a rotor shaft in a least three rows staggered uniformly in relation to one another in the peripheral direction. The prongs are further substantially rectilinear and rigidly fastened substantially tangentially on the rotor shaft. Furthermore the prongs enclose in relation to the radii associated with their fastening points an angle of less than 90.degree., the length of each prong being substantially in the proportion of 2:1 to the diameter of the rotor shaft and the prongs are pointed at their outer ends and curved in blade form in the direction of rotation.
