PROBLEM TO BE SOLVED: To solve problems that in conventional technology, the angle of inclination of a ground implement to a tractor is not changed when viewed in a plane by longitudinally moving lower links relatively to the tractor and effects of reduction in soil resistance in change of operation width and in operation and correction of the implement making parallel with the machine body of the tractor for avoiding the interference with the machine body during a rise are not expected. SOLUTION: The ground implement 2 is connected to the tip parts of the lower links 1 and 1, the base end parts of the lower links are connected to right and left hydraulic cylinders 3 and 3, respectively so that the implement is joined to the rear part of the tractor 4. The support controller of the tractor implement moves the lower links 1 and 1 forward and backward and the right and left inclination angles of the ground implement 2 to the tractor 4 when viewed in a plan are adjusted.
