The article introduces a modified model for the movement of universal all-wheel drive traction vehicles of the Mercedes-Benz Unimog type on a deformable surface (according to the WES methodology of the US Army). The model is created in the MATLAB Simulink software environment, namely a software module for determining the maximum traction force that can be implemented on any support surface. By investigating the influence of design parameters and operating conditions on traction properties, this model helps in selecting appropriate equipment for technological operations, and a trailer for transportation purposes. The researchers also explore ways to increase the traction properties of a wheeled vehicle and reduce the negative impact on soil fertility. Through this simulation model, the researchers obtained the value of the free traction force of a universal wheeled vehicle of the Mercedes-Benz Unimog type (based on the project of the Open Joint Stock Company “Ukravtobusprom” – TUR VT-041 “Avtotrak”), determined its traction class according to the classification, and selected the appropriate technological equipment and a trailer. The adequacy of the elaborated methodology is assessed by comparing the results of experimental data of the wheeled tractor T-150K and the results of the corresponding simulation model, i.e. calculation by applying the above-mentioned module. The article highlights the problem of insufficient access to low-tonnage wheeled vehicles for small farms and utility companies. Importing such equipment often becomes an expensive and complicated process. To address this issue, it is expedient to study the expertise of the Western European countries after the Second World War and the current situation and to develop a concept of a universal wheeled vehicle of the N1/T1 category of the Avtotrak/Unimog type. This concept aims to create a vehicle that can perform various tasks in the conditions of small farms and utility companies by combining the functions of a small tractor with high traction and an all-wheel drive truck that can move on and off-road.
