An engine-driven machine having plural kinds of load devices driven by an engine is provided with a load torque calculation unit that calculates a present load torque applied to the engine from a load device of at least one kind, and a control unit that performs variable control of a maximum output characteristic of the engine in accordance with the calculated load torque, such that a maximum output torque that can be outputted by the engine at the present engine revolution speed becomes a maximum output torque that is equal to or greater than the calculated load torque.
