The present invention relates to a grader for agricultural machinery attachment, by which, if the width of the agricultural machinery gets bigger, the agricultural machinery is rotated to maintain the horizon so that a grader job can be performed to a blind spot due to the agricultural machinery. More specifically, a first frame is included to rotate left/right in the front of a connection frame for detaching or attaching the agricultural machinery; a second frame is connected to rotate left/right in the front of the first frame, and a blade part in which front/rear blades are formed is included to rotate up/down in the front of the second frame; a first operating machine which allows the blade part to rotate left/right with input and output operations by jointing each side of the first frame and the second frame; and a location control part which controls the location of the blade part by jointing each side of the first frame and the second frame. If the width of a working machine is smaller than that of the agricultural machinery, the blade part of the working machine is rotating-moved so that a blind spot of a working object is not generated to control a movement distance of the working machine, and, accordingly, the movement distance can be controlled according to a characteristic of a workshop which requires the grader job. |
