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.

Abstract: A push cart includes a wheel, a motor, an obstacle detector, and a controller. The motor is configured to generate a rotational force that rotates the wheel. The obstacle detector is configured to detect an obstacle. The controller is configured to execute, in response to detection of the obstacle by the obstacle detector, avoidance control to control driving of the motor such that a movement of the push cart is limited. The controller is configured to disable execution of the avoidance control in response to a determination that a specified disabling condition is satisfied.
