PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of preventing a support member of a rotor and a suspension member of the rotor from interfering with each other when the rotor is moved upward, achieving satisfactory planting accuracy, and thereby performing appropriate soil preparation.SOLUTION: The seedling transplanter includes: auxiliary wheels 12c 12d mounted on travel wheels 12a, 12b； a seedling planting part 3； rotors 39； plural rotor holders 203 suspending plural rotor support frames 205 and the rotors 39 so as to be moved vertically； and rotor arms 209 connecting lower parts of the rotor support frames 205 and lower parts of the rotor holders 203. The rotor holders 203 are arranged between the travel wheels 12a, 12b and the auxiliary wheels 12c, 12d. Connection pipes 217 connecting the respective rotor arms 209 are arranged in lower parts of the rotor arms 209. When a seedling planting part 3 is lowered, the rotor holders 203 are prevented from interfering with the travel wheel 12b. When the rotors 39 are lifted, the connection pipes 217 are prevented from coming into contact with the rotor support frames 205.SELECTED DRAWING: Figure 15
