PROBLEM TO BE SOLVED: To provide a subsoiler implement reducing resistance during operation and mounted in addition to an implement. SOLUTION: This subsoiler implement can be mounted through a three-point link on a tractor to perform harrowing, tillage, land grading, or the like, and is equipped with a supporting arm for each digging reversal body mounted on a constituent frame or on a supporting frame member separate from the constituent frame and having a length in the operation width direction overhanging toward the operation forward direction and the digging reversal body mounted on the supporting arm for the digging reversal body. The implement is composed as follows. Digging reversal operation and other operations subsequent thereto can be performed and the digging starting point of the digging reversal body is in front of the constituent frame of the subsequent implement and near the position of the centroid of the tractor. Thereby, the ground contact pressure of drive wheels is improved by lowering of the centroid of the tractor. COPYRIGHT: (C)2005,JPO&NCIPI
