The extended land grading body is composed so that the side of the outer end of the extended land grading body 31 in the developed operative state is lowered and located below the land grading body 21 by a reduction in the tilt angle of the land grading body 21. The extended land grading body 31 has a plurality of ground contacting surfaces 51 and 52, and 53 having different tilt angles to the horizontal direction when viewed from the side during the state of the developed operative state.
