PURPOSE:To allow the self-travel transfer safely in a narrow area by automatically stopping the travel when the change of the longitudinal tilt angle of a vehicle body within a predetermined time is a preset value or more in a working vehicle such as a combine. CONSTITUTION:The presence of the lateral displacement of a machine against grain straws to be reaped and the displacement direction are detected by a displacement detecting mechanism 7 and entered into a control means 19. On the other hand, the longitudinal tilt angle of the machine is detected by a sensor 12, and the tilt angle change is determined by a detecting means 18 and entered into the control means 19. The control means 19 judges whether the tilt angle change is a preset value or more, and if it judges that there is a change, it outputs signals to a stop unit drive circuit 15, a clutch operating circuit 11 and a buzzer drive circuit 17 for the engine stop, buzzer warning, and travel stop. According to this constitution, self-travel transfer is allowed safely in a narrow area.
