The main objective in the design of agricultural tillage tools is for minimal material wear which provides the greatest workable lifespan without altering the performance of the tool. In the case of deep tillage ripper points, a welded hardsurfacing is used to offer added wear resistance to the winged surfaces of the point. Materials varying in composition were analyzed to determine the best resistance to wear. Through the use of a circular soil bin with abrasive sand for a soil medium, three test specimens were evaluated. Wear performance was gauged through physical measurements of leading edge wear and tool mass. The objective of these experiments was to compare the life cycle of each treatment and determine the material with the greatest wear resistance. It was also desirable to determine a relationship between mass and point loss in terms of a reduction in point length for the purpose of using mass as an indicator of tool performance.
