Sweep shovels fabricated using three different materials; two levels of each of heat treatment and edge thickness were field tested to establish differential responses of various parameters. Depth control wheels especially designed for the local sweep cultivator were also tested for their performance. Mild steel and medium carbon steel wore 89.3 and 64.3 percent faster than the high carbon steel. Local heat treatment though different from international methods, improved tool's wearing ability by 37.4 percent. As the edge thickness of tool increased from 6.35 - 7.94 mm, wear decreased by 2.7 percent. Depth wheels desirably controlled operational depth of the sweep cultivator.
