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
