Abstract
An electric working machine in one aspect of the present disclosure includes a motor, a setter, and a controller. The setter is configured to modifiably set a change characteristic in changing a rotational state of the motor from a low speed rotation to a high speed rotation. The high speed rotation is greater than the low speed rotation in rotational frequency of the motor.
