[Solution] A control method of a work machine includes executing the deceleration control when the deceleration condition is satisfied and changing the rated rotational speed in accordance with an operation of the accelerator operation portion 37. In the deceleration control, the target rotational speed of the prime mover 40 for driving the hydraulic pump 41 that discharges hydraulic oil is switched from the rated rotational speed to a first specific rotational speed lower than the rated rotational speed. Here, in the control method, when there is an operation on the accelerator operation portion 37 while the deceleration control is being executed, the deceleration control is continued.
