The invention discloses a remote-controlled mountain tractor, which comprises a frame (9), an engine (12), a gearbox (6), a clutch, a driving wheel (5), a driven wheel (10), a crawler belt (16), and a hydraulic drive device (14), the signal receiving and processing device (15), is characterized in that: the left and right sides of the frame are symmetrically connected with a hydraulic pressure differential height device for adjusting the left and right balance of the body. The invention applies the remote control technology to the tractor, and each action can be controlled by the signal transmitting device, realized by the hydraulic drive device, and the operation is simple. Because the machine can remotely control the lifting of the height difference device on both sides according to the terrain conditions at any time, maintain the level of the fuselage and prevent rollover, and can also increase the height of the frame by simultaneously lifting the hydraulic cylinder to realize the cultivating operation of the conventional plow. It fully adapts to the working environment in rural areas, especially in mountainous and hilly areas, and completes operations such as arable land, dry farming variable water application, ridge mulching, and harvesting.
