The present invention simplifies a switching process for switching the usage of a molding plate, and prevents the interference of a grounding body in a worker. The grounding body (11) and a molding body (12) are formed to be shakable around a shaft core located along the width direction of a driving machine body (1) in the following posture conditions: a first posture condition making the grounding body (11) be in a non-working posture by crossing the grounding body (11) and the molding body (12) to locate the lower end of the grounding body (11) to be in front of the molding body (12) which is in a posture for compressing soil cultivated by a cultivation rotor (10); and a second posture condition making the grounding body (11) be in a working posture by crossing the grounding body (11) and the molding body (12) to locate the lower end of the grounding body (11) to be in the position lower than the molding body (12) which is in a non-working posture located on the upper side of a working posture. |
