The agricultural machine can be offset into a working state and a storage state by operating a portion 88 of the agricultural machine by an actuator 84 using the control of a control unit in a control box 33 disposed in the agricultural machine, on the basis of the operation signal received. A switch 331 for emergency operation is provided in the control box 33, and the switch 331 for emergency operation is operated. Then, the control unit operates an expansion and contraction of an electric hydraulic cylinder 84 being the actuator, and the working state is brought into the storage state. |
