Elucidating rice transplanter’s behavior is important for the safety. In this study, a model of a rice transplanter with four degrees of freedom and installed with a fixed front axle was considered. Vibrations from the planting mechanism were also considered. The parameters of the model were identified based on experiments. The rice transplanter’s behavior on accident site was simulated, and the influences of the speed and mass center position on an anteroposterior fall were considered. The results showed that when the running speed is 0.09 m/s or lower, the influence of speed on the anteroposterior fall is small and the optimum location of mass center position is at a distance of 46 %-48 % of the wheelbase from the rear axle.
