PROBLEM TO BE SOLVED: To provide a paddy field implement of transplanter in which a planting device is mounted on a lifting link mechanism disposed in the rear portion of a travel machine frame through a rolling control mechanism, which gives a constant leveling depth without affecting the rolling control of the planting device with the resistance of a field-leveling member and improves the lifting control and rolling control of the planting device. SOLUTION: This transplanter in which the planting device is mounted on the lifting link mechanism disposed on a travel machine frame through a rolling control mechanism is characterized by disposing a leveling member for leveling the unevenness of a field on the rolling control mechanism. The rolling control mechanism comprises an intermediate member capable of being laterally rotated with respect to the lifting link mechanism, an actuator for forcibly rolling and controlling the intermediate member to a set posture on the basis of the detection of a rolling detection sensor, and rolling springs which are disposed between the intermediate member and the planting device and roll and control the planting device in a driven state. The leveling member is disposed on the intermediate member. COPYRIGHT: (C)2004,JPO
