FIELD: agriculture.
SUBSTANCE: disc soil tiller comprises the main disc (1) with the mounting opening (2) in the center, and the cutting and crumbling sharpened discs (7) made hemispherical and freely-rotating, installed around the main disc (1) circumference. The cutting and crumbling sharpened discs (7) are mounted on curved elastic radial arms (3) of circular section through the hubs (5) with bearing assemblies (6) at their ends, the location axes (8) of which are arranged around the circumference with a radius greater than the radius of the main disc (1) and at an angle to the fastening axes of the curved radial arms (3) of the main disc (1).
EFFECT: increased efficiency of surface soil loosening, reducing the draft resistance and extending the tiller service life.
