FIELD: agricultural engineering. SUBSTANCE: ripping chisel has a tine with its front and back facets shaped as Archimedean spiral. A cutting plate with a sharpened lower edge is rigidly secured on the front facet. The cutting plate is axially bent, and its working surfaces are positioned one over the other at a blunt angle. The cutting plate surfaces are concave along a section of Archimedean spiral. The concavity is directed towards the axis of symmetry of the tine. EFFECT: higher tillage quality. 3 dwg
