PROBLEM TO BE SOLVED: To prevent a state in which a marker is broken by coming into contact with a ridge between rice fields, when an automarker function is equipped in a paddy field working machine having left and right markers. SOLUTION: The paddy field working machine is equipped with a turning detection means for detecting initiation of turning and a travel distance detection means for detecting the travel distance of the machine body based on the rotation number of a wheel. The end of turning is detected based on the initiation of turning detected by the turning detection means and the travel distance of the machine body detected by the travel distance detection means. A marker control means which operates a marker in a working posture to be a housed posture when a grounding implement 5 rises, and operates a marker 19 opposite to the marker 19 operated in the working posture to be the working posture based on the detection of end of the turning.
