Effects of tillage depth and forward speed on draft of three primary tillage implements were studied by using a tension load cell in clay loam soil. Implements included a moldboard plow, a disk plow and a chisel plow, each of them with one tillage unit. A photoelectric speed sensor was used for measuring forward speed. The effects of forward speed and tillage depth on draft measurements were investigated through strip-split plot design. A significant increase in draft was observed for all the implements with increase in tillage depth and forward speed. Comparing of average draft in treatments with Duncan’s multiple range test showed that moldboard plow in highest forward speed and tillage depth had maximum draft and disk plow in lowest forward speed and tillage depth had minimum draft values. The relationships between draft and forward speed are presented graphically.
