WALK-BEHIND HAND-GUIDED WORKING MACHINE

A walk-behind electric device includes a device body, a moving wheel, a moving motor, a power interface, and a control unit. The moving wheel is connected to the device body. The moving motor is configured to drive the moving wheel. The power interface is connected to a power supply so as to supply power to the moving motor. The control unit is configured to identify, according to device parameters of the walk-behind electric device, an auxiliary operation that a user wants to perform on the walk-behind electric device, where the auxiliary operation is at least partially positively correlated to at least one output parameter of the moving motor.
