In succession to Part 1, the forced vibration experiment has been performed to clarify the vibration characteristics of the riding tractor with rotary tiller on the frequency ranging from 1.0[Hz] to, 10.0[Hz]. First, spring constant and viscous damping coefficient in the forward direction of the tractor were identified by phase method. Secondly, the simulation of frequency response was calculated, and simulated data were compared with measured data to discuss the validity for dynamic model. As a result, the factor which influences the difference between the simulated and the measured data in the frequency range beyond 6.0[Hz] was clarified, and showed the possibility of the vibration characteristics prediction in the forward and the pitching direction of the tractor.
