Tillage techniques are oriented towards dramatic reduction in soil plowing depth and the number of operations to minimize soil environmental damage. Tillage operations should provide optimal conditions for the development of growth plants. Literature review shows tillage used 60% of total mechanical energy. The required draft force of plow implements can be significantly reduced by the vibration of its shanks which are involved with the soil. Because of the less contact of tools with soil during vibration, the draft force is reduced. On the other hand, vibration reduces soil resistance with reducing the cohesion and its effective tensions in the dry soils. For deep tillage such as subsoilers with have high draft, using vibration to reduce the draft force desirable. According to the high draft force of tools vibration can be useful. Vibrating mechanisms was designed and manufacture for field performance evaluation of double bent blade. Vibration double bend blade was designed by Solid Works 2013 software and components analysis was done by Abaqus 2013 Software. Some physical and mechanical properties of field soil were measured. The effect of vibration frequency, soil moisture content and soil depth of tillage on the draft force, disturbed soil surface area, mean weight diameter and specific draft force was investigated. Two different frequencies (F 1 = 2 Hz, F 2 = 0.88 Hz), two different moisture content (M 1 = 0.9 PL, M 2 = 0.7 PL), two different tillage working depths (D 1 = 100 mm, D 2 = 200 mm) were considered. ANOVA showed vibration frequency and tillage working depth on draft force were significant (LSD 0.1%), but the effect of soil moisture content was not significant. The mean values of draft force for the vibration frequencies of 2 and 0.88 Hz were 22.2 and 5.37 kN. Effects of vibration frequency and tillage working depth on the disturbed soil surface area were significant (LSD 0.1%), but the effect of soil moisture content was not significant. The mean values of disturbed soil surface area for the vibration frequencies of 2 and 0.88 Hz were 1439.52 and 1354.77 cm 2 . Effects of vibration frequency and tillage working depth on the specific draft force were significant (LSD 0.1%), but the effect of soil moisture content was not significant. The mean values of specific draft for the vibration frequencies of 2 and 0.88 Hz were 14.08 and 44.63 kN/m 2 .Effect of vibration frequency and tillage depth on the mean weight diameter of soil were significant (LSD 5%), but the effect of soil moisture content was not significant. The mean values of mean weight diameter of soil for the vibration frequencies of 2 and 0.88 Hz were 15.71 and 17.93 mm.The vibration frequency of 2 Hz, soil moisture content of 0.7 PL and tillage depth of 100 mm, resulted in the low draft force that its value was 904 Newton. The vibration frequency of 2 Hz, soil moisture content of 0.7 PL and tillage depth of 200 mm, resulted in the high disturbed soil surface area that its value was 1966.83 cm 2 . The vibration frequency of 2 Hz, soil moisture content of 0.7 PL and tillage depth of 100 mm, resulted in the low specific draft that its value was 10.027 kN/m 2 . The vibration frequency of 2 Hz, soil moisture content of 0.7 PL and tillage depth of 100 mm, resulted in the low mean weight diameter that its value was 14.819 mm 2 .
