The paper shows the results of deformation and strength calculations in elastic-dissipative couplings of wheeled tractor dynamic system, which power is 110 kW when simulating its motion for a reference track with random profile. Spectral analysis shows the effectiveness of adjustable wheel suspensions on decrease in tractor loading and the impact on the road or the soil. Values of dynamic deflections for wheel suspensions with the optimal parameters were found.
