A useful model refers to agricultural machinery, in particular, to tools for soil tillage without loosening.The working body of the cultivator-planarar has a stand fixed on it with a main paw having wings with flaps bent upwards and cutting edges, the contour of which is made in the form of smoothly conjugated segments of a logarithmic spiral. In this case, it is provided with additional removable knives in the form of wing-shaped wings mounted behind the stand at the crushing angle and connected to it by means of a bracket. Moreover, the cutting edge of each wing of additional knives copies the back edge of the wings of the main paw, and the distance between them in the longitudinal direction is not less than 100 mm. In addition, the plane of the cutting edge of the wings of the additional knives is located below the plane of the cutting edge of the wings of the main paw. The back edge of the wings of the main leg is provided with bars of equal length parallel to the plane of their cutting edge, the length of the bars being greater than the distance between the back edge of the main leg and the cutting edge of the wings of the additional blades in the longitudinal direction, and the distance between the bars in the transverse direction is 30 mm. On the lateral edges of the wings of the additional knives are installed obliquely located rollers at an angle to the direction of movement, and their rear edge is equipped with bars having different lengths, the distance between the bars in the transverse direction is 50 mm. The width of the additional knives is equal to the width of the main paw. 3 z.p. f-ly, 3 ill.
