Disk are provided with main left- and right-hand teeth and auxiliary teeth positioned between main teeth. Left-hand teeth are fixed along perimeter of carrier disk at an angle with respect to disk plane, with tooth cutting edge being oriented from disk rotation axis to the left and rearward in the direction of rotation. Tooth has one-side sharpening and beveled end. Shape and attachment method of right-hand teeth are similar to that of Left-hand teeth and make mirror image. Right-hand teeth are positioned in teeth gaps of Left-hand teeth. EFFECT: increased efficiency, wider operational capabilities and enhanced reliability in operation. 3 cl, 3 dwg
