Abstract: 

Soil has hard particles that can scratch and wear steel. This type of wear is called abrasive wear. Abrasive wear is the main factor Limiting the life and performance of shares and other tillage tool

components. Shares wear fast and this has a considerable effect on performance of the plow. In this research, abrasive wear near the edge of shares in a semimounted four-bottom moldboard plow was studied. The soil was sandy clay with 13-17% moisture content. It was found that, near the edge of shares, the amount of wear with respect to distance from the tip of share was a polynomial function of second or third degree with determination coefficient of 0.94 or 0.98, respectively. Over 55% and 75% of wear occurred at 1/6 and 1/3 lengths of the blades respectively and only 16% of wear occurred at second half of the blades. Shares were worn unevenly but this unevenness was nearly the same in all shares. It is recommended that for decreasing the amount and the unevenness of wear, focus on increasing the wear resistance at regions that are worn faster. These regions are 1/6 to 1/3 lengths of each share from the tip.
