PROBLEM TO BE SOLVED: To provide a paddy field working machine which can absorb even the comparatively large unevenness of a ground (plough pan) reasonably, remaining an advantage to absorb the comparatively small unevenness of the ground (plough pan) by lifting right and left wheels with a suspension mechanism. SOLUTION: The paddy field working machine comprises a support arm 48 which is rockable up and down around the front and rear axis line P8 of a machine body. and extended to right and left sides from the front and rear axis line P8 of the machine body. The right wheel 2 is supported on the right side of the support arm 48 via a suspension mechanism 49, and the left wheel 2 is supported on the left side of the support arm 49 via the suspension mechanism 49, so that the right and left wheels 2 can be freely moved up and down.
