A shovel includes a lower-part traveling body, an upper-part turning body mounted on the lower-part traveling body, a hydraulic actuator mounted on the upper-part turning body, an internal combustion engine disposed in the upper-part turning body, provided with a supercharger, and configured to be controlled at a constant rotational speed, a hydraulic pump connected to the internal combustion engine, and a controller configured to control horsepower absorbed by the hydraulic pump. The controller is configured to increase a load on the internal combustion engine with the hydraulic pump before a load on the hydraulic actuator increases.
