PROBLEM TO BE SOLVED: To provide a tillage leveling machine that has an extension leveling body in which the leveling function of a field surface is not reduced, even if the extension leveling body is brought into a high front low rear condition.SOLUTION: A tillage leveling machine 1 includes: a tilling rotor 9 receiving power from a traveling machine body 90 and supported rotatably; a top cover 11 covering the upper part of the tilling rotor 9; a first leveling body 12 turnably provided in the vertical direction at the rearward of top cover 11; a second leveling body 20 turnably provided in the vertical direction at the rearward of the first leveling body 12; and an extension leveling body 30 turnably provided in the vertical direction mainly on a turning central axis 23 extending in an oblique direction, while a front side is positioned inside in the leveling body width direction from the rear side to the traveling direction of the second leveling body 20 at left-and right-hand ends of the second leveling body 20. The extension leveling body 30 is provided with a lower turning amount adjusting mechanism 40 supported approachably and separably at a turning central axis 23, and capable of adjusting the turning amount to the lower part of the extension leveling body 30 by coming into contact with the lateral direction end of the second leveling body 20. |
