The aim of the thesis was to prepare a list of structures, used in tractors, with a focus on the chassis and axle types.Another point was to characterize the methodology for measuring the tensile properties of the concrete surface, which carries out the state testing laboratory in Nebraska.Further develop methodologies terrain measurement of tensile properties.After this, tabular and graphical data obtained from the state testing laboratory, which concerned wheeled and caterpillar tractor Challenger, where the issue of tensile properties was solved, have been processed. The terrain measurements on the stubble were chosen two tractors John Deere 8320R wheeled and caterpillar 8320RT. The measurement was focused on differences in tensile properties depending on the kind of the tractor chassis. From the analysis of the measured values shows that the caterpillar tractor has higher values of tensile properties in the measurement of on the concrete surface and on the stubble. The difference is caused by different contact surface of the chassis unit. On soft stubble there are differences in tensile properties pronounced because of deformation of the base. It is proven that we can achieve higher efficiencies of work with tracked tractor and with the fact lower fuel consumption because of better transmission of engine power.
