Abstract
An automatic running work vehicle which is adapted to repeat a running travel reciprocatingly and which has means for teaching the running course of one travel by sampling the running direction detected by an orientation sensor every predetermined running distance detected by a distance sensor during the travel and for steering the work vehicle based on the information of running course taught by the preceding travel when follower sensors fail to detect the boundary of the running course for a predetermined period of time.
