PROBLEM TO BE SOLVED: To solve problems that linear levees sometimes cannot accurately be formed by operation, meandering, etc., of a tractor in the formation of the linear levees or operation of operation residual corner parts of a field such as a paddy field and difficult operation such as reversing of the tractor is frequently performed by the operation in the operation handling of the operation residual corner parts of the field, etc. SOLUTION: This implement is equipped with a mounting frame 1, an operation part 3, an extensible rotating arm part 2 connected to the mounting frame 1 and the operation part 3 rotatably in the horizontal direction, respectively, a control part 4 for controlling the rotation and an operation part 5 for the control part. A connecting rod 7 urged and extended in the elongation direction with a spring 72 is stretched between the front position of an arm rotating shaft 14 on the side of the mounting frame 1 and the side of the operation part 3 of the rotating arm part 2. Thereby, straight advancing properties of the operation part during the meandering of the traveling machine or during operation in the surface intersecting the advancing direction at right angles are automatically corrected.
