PROBLEM TO BE SOLVED: To provide a paddy working machine controlling the attitude of a seedling-planting device non-parallel to a machine body even when a chemical-spraying device is mounted on the seedling-planting device.
SOLUTION: The seedling-planting device 6 is mounted on the machine body so as to roll around a rolling axis X, and a main balance spring 29 for returning the seedling-planting device 6 to an attitude parallel to the machine body and urging thereof is provided. The chemical-spraying device 1 is mounted on the seedling-planting device 6 so that the seedling-planting device 6 is controlled so as not to assume the attitude non-parallel to the machine body by mounting the chemical-spraying device 1. An auxiliary balance spring 45 for returning the seedling-planting device 6 to the attitude parallel to the machine body and urging thereof is provided over the machine body and a bracket 24b which is deflected and located in one of the right and left separated from the rolling axis X in the seedling-planting device 6.
