The purpose of this paper is to propose a newly agricultural tractor model, which enables to analyze vibration phenomenon due to the tire lug. The 6 DOF-tractor model includes the character of the tires modeled by spring-damper system, whose parameters were identified using the results of the tire excitation test and the modal analysis. We consider the amount of the tire lug vibration to be the equivalent of the spring-damper displacement amplitude. The input amplitudes were obtained by running road tests using one lug-pattern tire and three block-pattern tires. The calculated vibration amplitudes of the standard tractor (with all lug-pattern tires) were consistent with the experimental results. Thus, the validity of the proposed model and the method of identified parameters were confirmed.
