The report presents results of a 3D study of the contour and angles of subsoil shanks changes which develop due to wear caused by the soil during the ground cultivation. The results of 3D imaging were subject to the analysis aimed at the identification of the limit wear of the parts concerned. Significant differences were found in changes in the contour and angles of blades with regard to the design variants. The results of the study can indicate a need of further operation research to verify the suitability of certain variants of the blades exhibiting differences in terms of material and design.
