The circumstances that give rise to overloads in agricultural machinery and implements are increased in any territory due to demanding soil conditions and heavy soil characteristics. In agriculture, it is common to find examples of machines and implements, both domestic and imported, that suffer deformations in their structure or frequent breakages in their working parts. The determination of dynamic load coefficients that make it possible to obtain, with an acceptable degree of accuracy, the stress and deformation states in parts and structures subjected to impact loads, presents a high level of difficulty, especially when the elements subjected to the action of these loads have a configuration that is not simple, making it necessary to implement other methods that simplify the calculation and make it possible to deal with cases not considered typical. The paper presents a case study in which finite element analysis is applied as a tool during the determination of stresses and deformations in a structural element subjected to impact loads, compared with the calculation by traditional methods. As a result, it is found that during the calculation of structural elements by traditional methods, the dynamic load coefficients obtained give higher values of stresses and deformations than those obtained by finite element impact analysis.
