[Problem] To provide a series hybrid combine which, in order to improve the fuel consumption for an engine which is the drive source for a motor, uses as small (low output) as possible engine and generator, and, while doing so, is free of instances of the vehicle stopping that would have resulted from unexpected interruptions of the generator. [Solution] The series hybrid combine is provided with: a generator (81) driven by engine output a motor (82) driven by electric power from this generator (81) an electrical machinery control unit (85) that controls the generator (81) and the motor (82) a traveling device (1) that makes the vehicle travel by rotary power from the motor a vehicle speed setting operating device (OD) for setting vehicle speed according to an operating position and an engine rotation sensor (S2) that acquires engine rotational speed. Furthermore, the constitution is such that the motor (82) output torque is diverted such that the generating load on the generator (81) does not exceed the allowable load.
