Wider base of wedge is mounted on roller surface and narrower base is oriented lengthwise of roller side surface generatrix. Wedge is defined by two symmetrical joined sides. Flat parts of sides define axially symmetric knife segments with flat cutting edges. EFFECT: simplified construction, improved quality of tillage, increased efficiency by providing stable plant association on pastures and increased productivity. 5 dwg
