Claim 2:
3. The work machine according to claim 1, wherein
in a state where the power of the engine or the output of the hydraulic pump has decreased to a decrease threshold with the rotational speed detected by the rotational speed sensor being at the second rotational speed, the controller lowers the rotational speed of the engine from the second rotational speed to the first rotational speed; and
in a process of lowering the rotational speed of the engine to the first rotational speed, the controller outputs, to the regulator, a signal instructing adjustment of the discharge rate of the hydraulic pump so as to make the power of the engine or the output of the hydraulic pump have a value corresponding to a request load.
