PROBLEM TO BE SOLVED: To solve such the problem that in the conventional rice transplanter, when a travel vehicle body travels forward, in the case when a prescribed load on a seedling transplanting device which transplants seedlings, is produced, a missing plant movement distance of the travel vehicle body since power is turned off by a safety clutch mechanism until the travel vehicle body stops, is normally about 5 meters, but the distance cannot be determined correctly, and accordingly, in a period in which the travel vehicle body is moved backward by the missing plant movement distance and stopped, and the travel vehicle body is moved forward by the missing plant movement distance again, the prescribed load is produced, and a work for causing the seedling transplant device in which power to be transmitted is turned off by the safety clutch mechanism, to transplant the seedling, is not easy.SOLUTION: There is provided a rice transplanter comprising a controller 100 for performing control for causing a movement distance detection part 150 to detect a missing plant movement distance of a travel vehicle body 10 since power is turned off by a safety clutch mechanism 130 until the travel vehicle body 10 stops.SELECTED DRAWING: Figure 4
