PROBLEM TO BE SOLVED: To provide a working stage changeover structure for a mobile vehicle, which can automatically resume a work according to the end of a levee turning stroke, immediately after the working run restart of an engine even if the engine is stopped at the levee turning stroke.SOLUTION: In the case of a levee turning stroke, a control device 56 executes a measurement processing based on a command of measurement start command means M and a command of measurement completion command means N. When the measured distance obtained in the measurement processing reaches a control objective distance, a work device is switched from a non-working state to a working state. When a command of engine stop command means R is acquired during the execution of the measurement processing, the measured distance obtained in the measurement processing till the command is acquired is written in a nonvolatile storage device C, and the measurement processing is ended. When the start of an engine 7 is then detected on the basis of the output of an engine start detector S, the measurement processing is resumed, so that the attainment of the control target distance of the measurement distance is determined on the basis of the measured distance obtained in the measurement treatment after the resumption and the measured distance before the command acquirement written in the nonvolatile storage device C. |
