A series hybrid combine realizes reduced engine noise and inhibited fuel consumption. The series hybrid combine is composed of an engine, a power generator driven by the output of the engine, a motor driven by the electric power from the power generator, a driving device enabling a vehicle to run by the rotation power from the motor, a vehicle speed setting operation member for setting the vehicle speed in a corresponding operation position, an engine control unit controlling the output of the engine, and a crop harvesting device for harvesting crops. The series hybrid combine further has an engine target rotation speed calculating unit calculating a target rotation speed of the engine based on the operation position, an actual load obtaining unit obtaining the actual load of the engine, a reference engine rotation speed calculation unit which calculates the reference engine rotation speed by using reference engine output characteristics and based on the actual load, and an engine instruction rotation speed calculation unit which calculates the engine instruction rotation speed based on the target rotation speed and the reference engine rotation speed, and outputs an engine control instruction based on the engine instruction rotation speed to the engine control unit.
