Última Draft force requirements of a dual bent blade subsurface tillage implement CIGR Journal Salar, Mahmood Reza; Esehaghbeygi, Ali; Hemmat, Abbas; Kargarpour, Hoda. Decreasing draft force of tillage tools is always one of the important concepts in tillage operation.  According to structure properties of bent leg, in this research, two upward and backward dual bent blade subsurface tools with two rake angles of 7.5 and 15 degree and two bend angles of 10 and 20 degree were developed and draft force, soil disturbance area and specific draft were compared in two soil moisture content levels of 0.7 and 0.9 of plastic limit (PL).  The effect of soil moisture content was not significant on any of the measured variables.  The draft force of the subsurface tools was increased with increasing rake and bend angles of blade.  The least mean of draft force was achieved in forward dual bent blade subsurface tool with bend angle of...
