PROBLEM TO BE SOLVED: To provide a management system utilizing a GPS satellite capable of discriminating a field where an agricultural work is performed accurately from among many fields. SOLUTION: An electronic control unit (ECU) 11 provided on a tractor 10 can display a field NO. where the tractor is positioned on map information having the field NO. added thereto on an information terminal monitor screen 12, relative to each field deduced and acquired by reception of a radio wave from GPS 13, and various kind of information including the field NO. is transmitted to a base station by radio communication from the ECU on the tractor and a portable terminal connected to the ECU. This system is equipped with a communication control mechanism of the portable terminal for starting automatically the radio communication when transmitting the various kind of information to the base station from the portable terminal, and cutting automatically the radio communication at the point of time of reception finish of the various kind of information at the base station; and a field discrimination information correction control mechanism for transmitting to the base station a command for correcting field discrimination information of an agricultural machine deduced by reception of the radio wave from the GPS into correct field NO. information when the field NO. is inputted from the portable terminal, and displaying it on the information terminal monitor screen of the tractor.
