A mowing vehicle 1 provided with a traveling machine 10 and a mowing device 20 includes a first image-capturing device 30 and a controlling unit C configured to control the traveling machine 10 to travel autonomously along a boundary line of grass before and after mowing formed by the mowing device 20. The controlling unit C includes a boundary-detecting unit C2 configured to detect the boundary line and a traveling-controlling unit C3 configured to control traveling directions of the traveling machine 10. The boundary-detecting unit C2 is configured to generate intensity distribution information regarding texture information in a predetermined direction by filtering with a Gabor filter on a captured image. The boundary-detecting unit C2 is configured to carry out statistical processing on the intensity distribution information per inspection area divided in plural in a vertical direction so as to detect boundary points and to detect the boundary line from the boundary points per the inspection area.
