This paper concerns with experimental verification of the theory on the safe VHP positions presented in the first part of this study. In the experiment, tillage operation was conducted using a plow mounted to the threepoint hitch and the forces acting on the hitch points were measured. Using the data from the test tractor and plow, computer simualtion was also conducted and its results were compared with those obtained from the field experiment. The comparison showed a reasonable agreement between the two results, by which the theoretical method for the determination of safe VHP positions for steering control can be verified. Some guidelines for expanding the safe VHP region were finally proposed.
