A device for adjusting a horizontal level of a tractor is provided to improve a working efficiency, to prevent a part from being damaged previously by protecting a length adjusting unit from foreign matters, like a dust, and to reduce a maintenance cost considerably. A device for adjusting a horizontal level of a tractor includes: a main body(10), one side of which is connected to the rear side of the tractor, and having an inside space; and a rod(20), one side of which is inserted into the inside space of the main body and the other side of which is connected to a working tool, as well as which is moved backward and forward by a length adjusting unit. The length adjusting unit comprises: a rotating shaft, one side of which is mounted by a bearing inside the main body, and the other side of which is engaged with a connecting hole which is arranged in one side of the rod; a rotating gear, on one outer circumference of which many threads are formed so that it is engaged with a thread formed on one outer circumference of the rotating shaft; and a driving motor, connected to the other side of the rotating gear and controlled by a controller so as to rotate the rotating gear and to lead the rod into or out of the main body. |
