The work machine includes: a power device that drives rotation; a work device that operates using the power device as a power source; and an instruction device that instructs an increase and a decrease in rotational speed of the power device. The instruction device includes a first instruction device and a second instruction device. A minimum change unit of the rotational speed of the power device that can be instructed by the first instruction device is different from a minimum change unit of the rotational speed of the power device that can be instructed by the second instruction device.",
