The Finite Element Model (FEM) has been used to predict the soil behavior disturbed by tillage tool, as well as the necessary draft force to break it. The aim of the present work is to analyze, by a simulation model of soil-tillage tool interaction in finite element, the draft force behavior of the vibratory subsoiler bent leg (narrow farming tillage tool), tilling a Ferralitic soil block, using the linear form to the extended Drucker-Prager elastoplastic constitutive relation model. The software used was Solid Works and its complement Simulation to model the vibratory bent leg and the soil block. The mechanical properties of soil were determined in the soil box CS-CEMA-25 and assigned to simulation model which was analyzed in function of moisture, bulk density, working depth and forward speed. The results showed the FEM reliability to predict the draft forces behavior of narrow tillage tool.
