PROBLEM TO BE SOLVED: To provide a work vehicle capable of preventing an operator from being misunderstood when a positioning state changes frequently. SOLUTION: A positioning unit 43 that receives a positioning signal from a satellite positioning system and measures the position of its own vehicle based on the positioning signal, determines the positioning accuracy based on the positioning state of the positioning unit 43, and determines the positioning accuracy. The control unit 60 that permits automatic traveling when the accuracy is higher than the accuracy, the first notification indicating that the positioning accuracy is the first accuracy equal to or higher than the predetermined accuracy, and the positioning accuracy are predetermined according to the control by the control unit 60. It is provided with a notification unit 66 that executes a second notification indicating that the second accuracy is higher than the accuracy, and within the first predetermined time after executing the first notification according to the transition of the positioning accuracy to the first accuracy. When the positioning accuracy satisfies the condition for transitioning from the first accuracy to the second accuracy, the first notification is continuously executed until the second predetermined time elapses, and the first notification is performed after the second predetermined time elapses. It is configured to end the notification and execute the second notification.
