This work vehicle is provided with: a positioning unit that receives a positioning signal from a satellite positioning system, and measures the work vehicle position on the basis of the positioning signal; a control unit that determines the positioning accuracy on the basis of the positioning status of the positioning unit, and permits autonomous travel when the positioning accuracy is at least a prescribed accuracy; and a notification unit that executes, in accordance with a control performed by the control unit, a first notification indicating that the positioning accuracy is a first accuracy that is at least a prescribed accuracy and a second notification indicating that the positioning accuracy is a second accuracy that is at least a prescribed accuracy.

Abstract: A display section displays information related to a plurality of fields. The operating section accepts a selection operation for one of the plurality of fields displayed on the display section. If the operating section accepts a selection operation for the one field, and if the position information acquired by the positioning unit corresponds to a position within the one field, the control section controls the display section to display a start button for starting the operation of the fertilizing apparatus. If an operation to the start button is accepted by the operating section, the control section starts the operation of the fertilizing apparatus, based on the work information for the one field stored in the storage section.

Abstract: A rice transplanter is configured so as to be capable of, while utilizing a satellite positioning system to specify the rice transplanter position, autonomous travel along a travel route set parallel to a reference route generated on the basis of preset points A and B. The rice transplanter is provided with a control unit that, during autonomous travel, activates a notification device if the rice transplanter position approaches a ridge-adjacent position L1 specified on the basis of point A or a ridge-adjacent position L2 specified on the basis of point B. The control unit is configured so as to be capable of changing one of the ridge-adjacent position L1 and ridge-adjacent position L2 to a ridge-adjacent position L3 specified on the basis of a point P different from points A and B. After said change, the control unit activates the notification device on the basis of the ridge-adjacent position L3 instead of said one of the ridge-adjacent position L1 and ridge-adjacent position L2.

Abstract: An automatic traveling system causes an agricultural work machine to automatically travel a first route and a second route in sequence, wherein the agricultural work machine supplies supply material to the first route and the second route while traveling along a travel route that is set in a field and comprises the first route formed by connecting a first start point and a first end point and the second route formed by connecting a second start point and a second end point. The automatic traveling system includes a correction route generation unit that generates a corrected travel route in which the second start point and the second end point are switched when a prescribed condition is satisfied after the agricultural work machine automatic travel is aborted before entering the second route, and before the agricultural work machine automatic travel restarts on the second route.
