PROBLEM TO BE SOLVED: To provide a seedling transplanter which can easily plant seedlings into proper positions of a farm field.SOLUTION: A seedling transplanter 1 comprises: left and right front wheels 12a arranged at a front part of a traveling vehicle body 2 which travels in a farm field so as to be steerable by a handle 31 left and right rear wheels 12b arranged at a rear part of the traveling vehicle body 2 a calculation part 101 which calculates an ideal traveling trace of the farm field a storage part 102 which stores an actual traveling trace of the traveling vehicle body 2 of the farm field and a control part 103. The control part 103 steers the left and right front wheels 12a so that the actual traveling trace is overlapped with the ideal traveling trace on the basis of the ideal traveling trace calculated by the calculation part 101 and the actual traveling trace stored in the storage part 102.COPYRIGHT: (C)2014,JPO&INPIT【課題】圃場の適切な位置に苗を容易に植え付けることができる苗移植機を提供する。【解決手段】苗移植機1は、圃場を走行する走行車体2の前部にハンドル31によりステアリング操舵可能に設けられた左右の前輪12aと、走行車体2の後部に設けられた左右の後輪12bと、圃場の理想の走行軌跡を算出する算出部101と、圃場の走行車体2の実際の走行軌跡を記憶する記憶部102と、制御部103とを備える。制御部103は、算出部101が算出した理想の走行軌跡と、記憶部102に記憶された実際の走行軌跡とに基いて、実際の走行軌跡が理想の走行軌跡に重なるように左右の前輪12aをステアリング操舵する。【選択図】図3
