PROBLEM TO BE SOLVED: To provide a paddy field working machine advantageous in transportation and storage without causing deterioration in turning property and stability of a machine body in working.SOLUTION: A first working device A wider than the breadth of a travel vehicle body is configured to be changeable between a working state where a first working part 14 coupled to the rear part of the travel vehicle body via a coupling mechanism, and a second working part 15 coupled to the first working part 14 via a coupling part 16 are horizontally aligned adjacent to each other, and a storage state where the second working part 15 is displaced to the first working part side and the lateral width thereof becomes narrower than that in the working state. A second working device B narrower than the first working device A is coupled to the first working device A via a coupling frame 86 so as to displace between a working position adjacent to the first working device A and a retraction position separated from the firs
