The invention relates to a 6 * 4R tractor drive axle power system which comprises an intermediate drive axle which comprises an intermediate axle bearing air bag and a first air pressure sensor for detecting the air pressure of the intermediate axle bearing air bag. The lifting drive axle comprises a rear axle bearing air bag and a second air pressure sensor for detecting the air pressure of the rear axle bearing air bag; the power disconnecting mechanism is connected to the middle drive axle and the rear lifting drive axle so as to control the combination and disconnection of the middle drive axle and the rear lifting drive axle; and the electronic control unit is used for controlling the connection and disconnection of the power disconnection mechanism according to the pressure values of the first air pressure sensor and the second air pressure sensor, and controlling the lifting drive axle to be in a lifting state and a falling state. The working modes of the tractor can be automatically controlled and switched according to the actual working conditions of the tractor, the operation economy of the tractor is improved, the tire loss and the fuel consumption of the whole vehicle under the no-load or light-load working condition are reduced, and better operation economy is provided for the whole vehicle.
