Wear Resistance of Cultivator Tine (Part 1)

Distribution of Wear on Tine

Abstract

In order to develop a high speed tiller for minimum tilling operation, knowledge of wear mechanism, among others, is a basic requirement. In one of the models of the high speed tiller, the wear mechanism of a cultivating tine is investigated to improve its wear resistance. In this paper wear characteristics is discussed. Wear improvement techniques is discussed in part 2 of this study. In this study, the amount of wear and condition of surface wear on the commonly used cultivator tine, together with tines coated with fine ceramics that would give a good wear resistance were investigated. The experiments were performed both in the laboratory and on the field at various runs. The results show that the maximum wear of the tine tip occurs at the center as well as at the extreme edges of the tip. The amount of surface wear is proportional to the depth of penetration of the tine. The surface which is coated with fine ceramics is observed to show minimum wear.
