In order to achieve the above object, the present invention includes an electric push rod assembly, a farm tool power input shaft, a farm tool height controller, a front distance sensor, a middle distance sensor, a rear distance sensor, a left end farm tool mounting seat, a right farm tool mounting seat, and a farm tool height Adjusting seat, tractor main body, agricultural implement main body, battery; electric push rod assembly includes electric push rod shell, push rod, straight slide potentiometer slide rail, straight slide potentiometer handle; straight slide potentiometer slide rail is fixed on the electric push rod On the casing, the handle of the straight-slide potentiometer is fixed on the push rod, and the handle of the straight-slide potentiometer reciprocates on the slide rail of the straight-slide potentiometer with the movement of the push rod; the electric push rod shell at one end of the electric push rod assembly It is connected to the tractor frame in the form of a swivel pair, and the push rod at the other end is connected to the height adjustment seat of the farm tool in the form of a swivel pair. The power input shaft of the farm tool main body is fixed on the left and right farm tool mounts. The shaft can be rotated in the left and right agricultural implement mounts; the implement height controller and battery are installed in the main body of the tractor, and the front distance sensor, middle distance sensor, and rear distance sensor are respectively installed in the front and middle of the tractor chassis and the rear; implement height controller, battery, front distance sensor, middle distance sensor, rear distance sensor and straight slide potentiometer slide rail are electrically connected.

When the tractor is in operation, the front distance sensor, the middle distance sensor and the rear distance sensor respectively measure the height of the front, middle and rear of the frame from the ground, and the data are aggregated to the implement height controller; the implement height controller is based on the three The distance sensor data analyzes the terrain and controls the electric push rod assembly to do telescopic movement; the straight-slide potentiometer slide rail measures the movement distance of the push rod, and the data is fed back to the implement height controller to realize closed-loop control; when the push rod is doing telescopic movement , the main body of the farm implement rotates around the power input shaft of the farm implement to realize the height adjustment of the tail of the farm implement main body.
