Abstract

According to an aspect of the present invention, an electric working machine is provided. The electric working machine comprises a motor, an operation portion, a working portion, and a controller. The working portion is configured to be driven by the motor and act on a work target. The operation portion is configured to be operated by an operator. The controller is configured to control a maximum power that can be input to the motor to a first power when receiving an operation signal indicating an amount of operation to the operation portion. Further, the controller is configured to perform first switching control to switch the maximum power to a second power that is less than the first power when rotation speed of the motor becomes less than a first threshold due to a load on the working portion.
