The invention discloses a hand-push type working machine. The hand-push type working machine comprises a main body; a walking wheel set; the motor comprises a motor shaft for driving the wheels to rotate; a controller; the transmission mechanism is used for realizing transmission between the motor shaft and the wheel; the transmission mechanism has a first state and a second state, and when the transmission mechanism is in the second state, the wheel can freely rotate relative to the motor shaft; the operating part is operated to at least have a first operating state for controlling the motor to start and a second operating state for controlling the motor to stop; the controller comprises a rotating speed loop control module, and the input of the rotating speed loop control module comprises the target rotating speed of the motor; when the operation piece is switched from the first operation state to the second operation state, the target rotating speed of the motor is set as the first rotating speed, so that the transmission mechanism is switched from the first state to the second state; the first rotating speed is negative. By applying the negative rotating speed to the motor, shutdown tripping of the motor and the clutch is achieved, and the tripping reliability is high.
