PROBLEM TO BE SOLVED: To provide a paddy field working machine having a land grading apparatus between a paddy field working apparatus and a machine body and effective for avoiding the interference of the land grading apparatus with the paddy field working apparatus and the machine body in the case of making the paddy field working apparatus to enable free lifting and lowering motion and the land grading apparatus to enable free change of the height of the apparatus.
SOLUTION: The paddy field working apparatus 5 is supported in a freely liftable state at the back of the machine body through a link mechanism 3, and the land grading apparatus 53 is supported in a freely liftable state between the paddy field working apparatus 5 and the machine body. The machine is further provided with a changing means 56 to freely change the height of the land grading apparatus 53 relative to the paddy field working apparatus 5 or the machine body. The machine is additionally provided with a controlling means to apply a restriction on the change of the height of the land grading apparatus 53 by the changing means 56 according to the height of the paddy field working apparatus 5 relative to the machine body.
