  In this research, the effect of forward speed at four levels (1.8, 2.3, 2.9 and 3.5 km/h), tillage depth at three levels (30, 40 and 50 cm) and wing at two levels (winged and no-winged tines) were investigated on the draft requirement, soil disturbance area and specific draft of Paraplow. The results revealed that the effect of depth and wing was more than forward speed on the studied parameters, significantly. Increasing forward speed increased draft requirement and specific draft but decreased disturbance area. Increasing depth and adding wing led to increase draft requirement, disturbance area and specific draft. Transfering winged paraplow to under the hardpan decreased specific draft, significantly. The results recommended that using lower speed, minimum depth for hardpan breakage and wing will be better. A regression model included the speed, depth and wing width was developed to predict the draft requirement.
