The invention provides an electric tractor with an adjustable gravity center. The electric tractor mainly comprises a gravity center adjusting mechanism, a charging and DC-DC all-in-one machine, a power battery, a driving motor, an instrument panel, a force-measurable suspension device and a chassis. The power battery is installed above the gravity center adjusting mechanism and can adjust the gravity center position of the electric tractor in real time; the charging and DC-DC all-in-one machine is connected with the power battery and is used for charging the power battery and converting the voltage of the power battery into available voltage of vehicle-mounted electrical equipment; the driving motor serves as a whole vehicle power device and is mounted on a lower bottom plate; the instrument panel is installed below a steering wheel and can display the vehicle speed, the electric quantity information of the whole power battery and a single power battery and fault information in real time; the force-measurable suspension device has a force measuring function and can detect the traction resistance borne by the electric tractor in real time during tillage. On the basis of an originaldiesel tractor, electrokinetic transformation is conducted, the electrokinetic process is accelerated, environmental protection is facilitated, the gravity center of the electric tractor is adjustable, and the stability and traction performance of the electric tractor can be improved.
