The described model of a machine and tractor aggregates in the modeling environment MATLAB/Simulink is described in the article. The detailed description of the wheeled tractor subsystem is given. With the help of computer tests it allows to estimate the operating characteristics of machine and tractor aggregates. The results of the fulfilled tests are cited. The aim of the computer experiment is the evaluation of tractive and adhesion properties and fuel economic efficiency of the wheeled tractor during technological process implementation. The general view of the model of agricultural tractor in Simulink medium is presented. Sub-model of the tractor's engine, traction wheel and carcass is suggested. The main parameters of aggregate and work conditions are evaluated. The speed oscillogram in the technological cycle is displayed. The model allows carrying out the analytic researches of tractor's parameters of different composition with the help of computer testing. It may be used by the specialists during tractors completing substantiation.
