This invention discloses a center of gravity control system, an excavator, and a method for controlling the center of gravity of the excavator. The center of gravity control system includes a turntable, a center of gravity detector, a servo motor pump, a counterweight mechanism, and a controller. The controller is connected to both the center of gravity detector and the servo motor pump, receiving center of gravity position signals from the detector and controlling the servo motor pump to steer, causing liquid in the first and / or second liquid counterweight tanks to flow towards the solid-liquid mixture counterweight tank, or vice versa. The center of gravity control system provided by this invention has a simple structure and is easy to operate. The center of gravity control method enables manual and automatic adjustment of the machine's center of gravity, effectively improving the stability of the entire machine and enabling the excavator to adapt to multiple working conditions and perform multiple functions.
