FIELD: agriculture; machine building.
SUBSTANCE: invention relates to the field of agricultural machine building. Ploughshare is a part in form of plate having radius of curvature of cross section. An abrasion-resistant coating is surfaced on the back part of the ploughshare blade. On the working surface of the ploughshare along borders of undercutting area there are rolls made of abrasion-resistant material, the space between which is filled with a glue polymer composition with high resistance to abrasive wear.
EFFECT: higher resistance to abrasive wear and longer life of ploughshare.
