FIELD: agriculture.
SUBSTANCE: harrow has a frame and teeth rigidly fitted on it. The teeth are in form of solid metal bands. The bands are fitted vertically and are curved in the transverse-vertical plane along symmetrical broken lines with the same interval of curvature. At the summits of the projections, on the lateral sides of the teeth, perpendicular the direction of motion, cultivators are fitted with provision for removal. The rippers have articulated bushes along the whole length. The length of the bushes is determined from the relationship: Lb.=Gs.Wct, where Lb. is the length of the bushing, Gs. is the golden section, which is equal to 1.618, Wct. is the curving width of the tooth. The teeth of the harrow are symmetrically directed towards each other along their axes. The summits of projections of adjacent teeth are displaced from each other in the direction of motion by half the interval of projection of the teeth. The harrow has a weigh box.
EFFECT: higher quality of tilling.
