摘要： A working machine includes a machine body, an engine on the machine body, a motor/generator to perform an assisting action in which the motor/generator functions as a motor to assist the engine in driving and an electricity generating action in which the motor/generator functions as a generator to generate electricity using power from the engine, a battery to store electricity generated by the motor/generator, an operation actuator to perform an operation of the machine body, a starting action determiner to determine, upon operation of the operation actuator, whether the operation corresponds to a starting action for the machine body, a first setter to set, if the starting action determiner determines that the operation of the operation actuator corresponds to the starting action, a torque of the motor/generator for the assisting action or the electricity generating action to a first torque, and a second setter to set, if the starting action determiner determines that the operation of the operation actuator does not correspond to the starting action, the torque for the assisting action or the electricity generating action to a second torque differing from the first torque set by the first setter.
