Abstract
An electric working machine according to one aspect of the present disclosure includes an output shaft, a motor, a transmitting device, a drive device, a controller, and a current path. The transmitting device has transmittable allowable torque and transmits rotation of the motor to the output shaft. The drive device energizes the motor with electric supply from a battery in accordance with a command from outside the electric working machine. The current path is configured to be able to energize the motor with a current value larger than an allowable current value required to limit torque generated in the transmitting device due to rotation of the motor to the allowable torque or smaller.
