Loads transmitted by mechanical vehicles to soil result in its deformation and compaction. Increasingly bigger and more efficient machines affect the base they move on to a significantly greater extent. The purpose of this study with the use of digital simulation is to reduce expenses on costly experimental studies with the use of off-road vehicles or specially developed laboratory machines. The simulations were conducted using the Mechanical Event Simulation module, which is a part of the Autodesk Simulation Mechanical software. For each step, the simulation program provides the value of stress in all nodes of the base grid. The stress values obtained via dynamic simulations are consistent with the values registered under laboratory conditions. When classical experiments are replaced with numerical methods, not only the cost is reduced, but also the impact of weather conditions on measurement results is avoided and the time required for the study is shortened. The use of the described methods allows for design and selection parameters of exploitation pneumatics drive mechanism, which will significantly reduce the negative impact on the natural environment by machines in agrotechnical treatments and forestry. This is related to the environmental protection issues.
