<P>PROBLEM TO BE SOLVED: To sow seeds with excellent accuracy regardless of presence of inclination in the lateral direction of a traveling machine body by accurately detecting presence of failure in sowing seeds in respective seed feeders. <P>SOLUTION: A working part S includes a plurality of seed feeders A arranged in the lateral direction of the traveling machine body for intermittently feeding seeds stored in a seed tank 32 by a set amount by a feeding rotator 52 which can be rotationally driven and dropping the seeds toward a field. In the paddy field working machine, the working part S is connected to the rear of the traveling machine body in such a way as to roll around a rolling axis X in the longitudinal direction of the traveling machine body. The height of disposition of the feeding rotator 52 in each of the plurality of seed feeders A is set approximately equal to the height of disposition of the rolling axis X. Each of the plurality of seed feeders A includes an optical sensor 90 for detecting drop of seeds in a dropping feed pathway disposed for dropping seeds from the feeding rotator 52 toward the field. <P>COPYRIGHT: (C)2012,JPO&INPIT |
