PROBLEM TO BE SOLVED: To provide a paddy field working machine which can automatically perform lifting operation of a marker without any delay even in a structure of adopting a wide seedling planting device scheduled to plant many number of planting rows.SOLUTION: The paddy field working machine includes automatic operation means that can output an operation command to a marker operation device 60 to change over a marker 40 in a lowered use attitude, to a lifted nonuse attitude, besides an operation command by linkage means that outputs an operation command to change over the marker 40 to the lifted non-use attitude in conjunction with lifting operation of a main working device. The automatic operation means includes machine body condition discrimination means for discriminating whether the traveling machine body reaches a scheduled swivel position or not. The automatic operation means is configured to output an operation command to the marker operation device 60 on the basis of discrimination information that the traveling machine body reaches the scheduled swivel position, and to change over the marker 40 in the lowered use attitude to the lifted nonuse attitude.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2017,JPO&INPIT
