Description: A tillage tool operating in agricultural soil was considered as a cantilever beam subjected to fluctuating soil cutting resistance. A finite element model was developed to simulate the responses of the deflection, velocity, and acceleration of the shank. The soi I resistance consisted of transverse and axial components. A dynamic soil cutting model was developed to obtain the relationship between the applied soil resistance and the movement of the tillage tool. It was found that the resulting responses of the shank were related to the natural frequency of the system and the applied soil cutting resistance. The parameters of the tillage tool that affected the shank vibration were investigated. The peak values of deflection, velocity, and acceleration ofthe shank were proportional to the length of the shank and decreased as the stiffness of component increased.
