    • PROBLEM TO BE SOLVED: To provide a paddy field working machine capable of preventing muddy water in a field from being gushed away in a large quantity outward from both right and left sides of a working device. SOLUTION: A ground levelling device is disposed between a travelling machine body and the working device. The ground-levelling device includes ground-levelling rotators 62A and 62B to be driven and rotated around a horizontal axis, and a mud cover 66 for preventing muddy water from scattering onto the working device. In the ground-levelling device 53, the large-diameter ground-levelling rotator 62A and small-diameter ground-levelling rotator 62B have different outer diameters from each other, and are disposed in such a state that the rotators are driven and rotated around the same horizontal axis. A small-diameter cover portion 66B of the mud cover 66 is disposed in such a state that the rear end of the portion is located on the machine body front side from the rear end of a large-diameter cover portion 66A, and a muddy water passing space S2 is formed between the small-diameter cover portion 66B and the large-diameter cover portion 66A.

    • 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.
