Title: WORK VEHICLE AND AUTOMATIC STOP SYSTEM OF WORK VEHICLE
Abstract: [0001]    A work vehicle according to an embodiment includes: (i) a travelling vehicle body that includes a power source to a work part and a travel part; (ii) a communication unit that is able to transmit and receive signals to and from a portable communication terminal; and (iii) a control unit that is able to control the travel part on the basis of a signal transmitted from the portable communication terminal and received by the communication unit. A plurality of communication systems is provided between the communication unit and the portable communication terminal. The communication systems include a first communication system that is able to transmit a first signal from a portable communication terminal, and a second communication system that has a smaller communication area than that of the first communication system and is able to receive a second signal indicating that the portable communication terminal exists in a predetermined area.
