In this study, we have developed a behavior simulation program for tractors by using a Runge–Kutta method on the existing fixed support model and front–wheel pivot model, and through a comparative analysis, we examined the difference between the models and their usefulness. And the summary of the results is as follows. 1. As for front wheel reaction force, the fixed support model showed changes involving left–right symmetry whereas the front–wheel pivot model, as a whole, showed changes in fluctuation according to the motion of the machine. 2. As for rear wheel reaction force, the fixed support model showed changes involving left–right symmetry as with the front wheels whereas it showed in nearly equal levels at both left and right wheels for the front–wheel pivot model, thus verifying that the front–wheel pivot mechanism exercises huge influence not only on the dynamic characteristics of the front axle but also on those of the rear axle. 3. The rolling angle for the fixed support model was greatly influenced by changes in four–wheel reaction force, whereas the front–wheel pivot model did not show any changes when the front wheels were climbing the bump.
