PROBLEM TO BE SOLVED: To provide a paddy working machine that is relatively lightweight and is also reduced in mud pushing, and includes means capable of exhibiting a superior soil preparation function.SOLUTION: A first auxiliary leveling body 31 is positioned at the front side of a predetermined interval L1 between main soil preparation floats 30 and is disposed between adjacent first auxiliary soil preparation bodies 31 across a predetermined interval L2. A second auxiliary soil preparation body 32 is disposed in a front place of the predetermined interval L2 between the first auxiliary soil preparation bodies 31. Each of the second auxiliary soil preparation body 32, the first auxiliary soil preparation bodies 31 and the main soil preparation float 30 is disposed so that the left-and right-hand width of a soil preparation range becomes narrower as the front side in the traveling direction.
