<P>PROBLEM TO BE SOLVED: To provide an expanded auxiliary landing plate rotation device of an agricultural work vehicle, capable of suppressing an increase of cost when changing a synchronization arm damaged or the like. Ž<P>SOLUTION: There is provided a puddling implement 1 having an extended auxiliary leveling plate set freely rotatably around a shaft extending longitudinally, at the end in machine width direction of a second extended leveling plate rotatably supported at the rear end of a first extended leveling plate 24 vertically freely rotatably supported on a shield cover 23 covering the upper part of a tilling rotor freely rotatably supported on a machine body 5. On the shield cover 23, a normal/reverse rotation motor 43, a gear transmission mechanism 47 attached on its axis and a joint 60 attached on a large gear 50 of the output side of the mechanism 47 are set to unitize, and an interlocked arm 53 connected to the joint 60 and rotating accompanied to rotation of the joint 60 is attached on the shield cover 23 separately from unitized normal/reverse rotation motor 43 and the like.
