Driving simulation using the motion equations based on the 3-dimensional dynamic model of the rubber crawler traction system was performed under various conditions. The location ar-rangement of track rollers was estimated through the experimental results and driving simulation. Components of vibrational acceleration of the rubber crawler traction system with 6 degrees of freedom could be measured individually and accurately using the new measuring method proposed by the authors. Accuracy of translational components of vibrational acceleration improved remarkably compared with the conventional measuring method. Motion equations and frequency transfer function of a riding tractor with rotary tillage equipment were proposed. Simulated data of frequency response were compared with measured data of forced vibration experiment to determine the validity for tractor’s dynamic model.
