  • Publication number: 20240023472
    Abstract: A work vehicle includes a car body, a traveling portion, working portions, operation display portions, and control portions. The car body can travel in a work field. The traveling portion makes the car body travel. The working portions conduct work on a target in the work field. The operation display portions output an operation signal. The control portions control the working portions and the traveling portion based on the operation signal. The control portions control the operation display portions so that the operation display portions display a travel control image and a work control image simultaneously with each other or at different timings from each other. The travel control image includes an image for operating the traveling portion. The work control image includes an image for operating the working portions.
