PROBLEM TO BE SOLVED: To provide a rice transplanter which can compact a structure for changing the attitudes of line-drawing markers and can prevent the damages of line-drawing markers, even when a push-up force acts during a work for forming a planting track.
SOLUTION: The rice transplanter having right and left line-drawing markers 72 for forming the planting tracks of the next step on the surface of a field and actuators 79 for lifting the line-drawing markers 72 from the surface of the field to places above the ground, wherein the line-drawing markers 72 are formed so as to be capable of being moved into a working attitude for contacting the line-drawing markers on the surface of the field or into a storing attitude for lifting the line-drawing markers from the surface of the field to places above the ground, the rice transplanter has marker arms 73 for supporting the line-drawing markers 72 on the end sides, holders 83 disposed at the base end portions of the marker arms 73 in an abutting manner, and marker-lifting gears 78 driven with the actuators 79, wherein the holders 83 are projectedly disposed on marker lifting gears 78, and the base end portions of marker arms 73 are pushed with the holders 83 to lift the line-drawing markers 72 from the surface of the field to places above the ground.
