With the emergence of new types of transmission and the increase of the maximum speeds of wheeled tractors, the study of the process of acceleration of the wheeled tractors with hydrovolumetric and mechanical transmissions has become a burning issue. The article represents the dynamics of the process of acceleration of the wheeled tractors Fendt 900 Vario. The article shows the mathematical model of the internal combustion engine, of the hydrovolumetric and mechanical transmissions; it describes the interaction of the wheels with a supporting surface; it presents the physical and mathematical models of acceleration of the wheeled tractors Fendt 900 Vario when running forward and reverse, with a trailer. The physical and mathematical models take into account the drawbar force and the slipping. The mathematical models of acceleration of the wheeled tractors Fendt 900 Vario during their operation permit to study the changes of the kinematic, force and energy parameters of the hydrovolumetric and mechanical transmission while slipping, and the effect of the hydrovolumetric and mechanical transmission on the process of slipping when running forward and reverse with a trailerReferences
