Abstract

PURPOSE: To enable the work in high efficiency with less meandering of the main body even with higher self-running speed, by the control depending on the amount of shift of steering wheel at automatic running so that the rotation of the steering wheel can be made only within a given range.
CONSTITUTION: With a tractor in self-running, the AND gate condition for an AND gate 11 is established, and the output signal is fed to an inoperative terminal 25 of a signal converting circuit (driving circuit) 16. Thus, the operation of the driving circuit 16 is inhibited and the operation of a steering hydraulic mechanism 17 is also inhibited. As a result, the front wheel 5 is inhibited to be rotated about 12° or more. Thus, since the front wheel 5 is subjected to too excessive displacement during the automatic control running, even if the tractor overpasses the boundary L with the dirdction control for the part, the front wheel 5 can be recorrected in a short time. Then, even if the tractor runs in remarkably high speed, almost no meandering is given.
