PROBLEM TO BE SOLVED: To provide a paddy field working machine for uniformizing soil in paddy field so as to enable uniform harvest of crops such as rice even in any part of fields without making the surface uniform but keeping the depth of plowed soil constant by making plowing bottom horizontal in preparing conditions of the paddy field. SOLUTION: This working machine is suitable for forming, in plowing the paddy field, the field with horizontal plowed bottom by working with the plow bottom of a bottom working machine surely keeping horizontal based on a reference plane, so that the thickness of the plowed soil is uniformized by working with the bottom lifting and lowering, wherein a sensor for detecting horizontality in the front and rear directions is set on a frame of the bottom working machine, the front end of the working machine is controlled by a horizontal signal received with a laser light sensor and attitude control of the rear end of the working machine is performed, by a gauge wheel or heel height, by the horizontal signal received with the horizontal sensor.
