Abstract

Ploughing is one of the most expensive tillage operations, which requires a large amount of fuel consumption and is accompanied by a heavy tractor load and intesive plough work part wear. Replacement of the latter involves high material and labour costs. The aim of this study is to find out whether the working parts of plough from different manufacturers have different yields, and therefore a comparative wear analysis is carried out in terms of weight and the longest diagonal length changes. The results of the study show that the plough points that were reinforced with hardening plates in the cutting edge and with wear-resistant weld coating on the working surfaces wore the least. The reinforced plough points wore 2,5 times less in mass and 4,53 times less in terms of the longest diagonal length than the original plough points. Original plough points and knife coulters yield is lower than the plough working parts of the other manufacturers used in the study. In general, the abrasive wear of geometrically identical parts is determined by hardness of the material from which the part is made.
