PROBLEM TO BE SOLVED: To provide a puddling working machine in which the plowing-in performance of straw existing in a field in the cultivated soil is improved, and an increase of cost can be suppressed.SOLUTION: A puddling working machine 1 includes: a first extension leveling plate left 26 L turnably supported in the vertical direction to the rearward of a shield cover left 25 L covering the upper part of a tilling rotor rotatably supported to an extension work body left 20 L a second extension leveling plate left 27 L turnably supported in this rear end an extension auxiliary leveling plate 55 turnably provided in the vertical direction to the outside end of the machine body width direction and a turning device 40 disposed on the shield cover left 25 L and turning the extension auxiliary leveling plate 55. A front side leveling plate 60 turnable in the vertical direction is provided centering on the front side shaft part extended in the longitudinal direction in the left side corner of the shield cover left 25 L, and the front side leveling plate 60 is turned while being linked with the extension auxiliary leveling plate 55 by the turning device 40.SELECTED DRAWING: Figure 1
