[Problem] To provide a working machine provided with an electric load application means and capable of burning particulate matter trapped in an exhaust gas purification system even when an electrical drive control system including an electric assist motor and electrical storage device is in failure. [Solution] A load application means, which applies a load to an engine 2 such that a temperature of exhaust gas is raised to a temperature required to burn particulate matter, is comprised of an electric load application means for applying the load to the engine 2 to raise the temperature of the exhaust gas by operating an electric assist motor 23 to generate electric power and a hydraulic load application means for applying the load to the engine 2 to raise the temperature of the exhaust gas by increasing a delivery pressure of a variable displacement hydraulic pump 4, and a selection control means is provided for performing control processing to selectively actuate the electric load application means and/or the hydraulic load application means. |
