This notification system enables communication over a communication device between a control device 10 of an agricultural work vehicle 1, a management server 3 of a management center 2 and a terminal device of a user 6, and the agricultural work vehicle 1 is provided with an inclination sensor 25 and connects to the control device 10. In energy-saving standby mode, during which a key switch 36 is switched off, if the value detected by the inclination sensor 25 is greater than or equal to a set angle of gentle inclination, then the control device 10 generates an alarm and notifies parties concerned, such as the user 6 and the sales outlet 8 in order to prevent theft of the vehicle. Further, the control device 10 generates an alarm if, during driving, the vehicle is inclined at greater than or equal to an angle at which there is a risk of overturning, notifies the parties concerned if the vehicle overturns, and, if there is no response from said parties, repeats the notification to secure assistance.
