Abstract
A dynamic model of the «operator – feller-buncher machine – object of labor – tree» has been developed. The mathematical description is in the form of the Lagrange equation of the second kind. The system of equations is solved for the elastic deformation of the operator's seat back by the Runge-Kutta method, using the MathCAD programming environment. Approbation of the model was carried out on the example of commercially available feller-bunchers machines LP-19A.
