FIELD: machine engineering, namely manufacture of soil tilling machines such as cultivators.
SUBSTANCE: in order to improve wear resistance of working organs of tilling cultivators made of steel 60C2A, after imparting desired shape to working organ subjecting it to preliminary heat treatment at hardness 40 - 48 HRC; then surfacing stripes onto working surface of working organ by means of electrode and performing chemical-and-heat treatment by means of nitrogen for providing hardness of working surface 55 - 62 HRC. Invention provides increased by 1.5 times wear resistance of working surface of working organ.
EFFECT: improved wear resistance of working organ.
