Development of new model-following control for a farm vehicle were discussed in Part. 3. In this paper, experimental results of running on a paddy field with the control are presented. The running tests were done on the field just after tilling and just after puddling. The result clearly shows that the side velocity and the yaw angular velocity of the test vehicle followed reference model quickly and stably with this developed control system. Furthermore, the system attenuated the influence on the motion of the vehicle due to unevenness of the field in order that it could run straightly in 40m steady running tests without divergence. The directional stability was improved with the system considering that the mean width of meandering was 0.24m.
