PROBLEM TO BE SOLVED: To provide a seedling transplanting machine that can further enhance accuracy of automatic straight traveling.SOLUTION: A seedling transplanting machine includes: a traveling vehicle body (2) with a steering wheel (4) being steered by a steering device (110); a seedling planting unit (50) connected to the rear of the traveling vehicle body (2) in a freely lifting/lowering manner; a position information acquisition device (120) for acquiring position information of the traveling vehicle body (2); a tilt detection unit (180) for detecting a longitudinal tilt of the traveling vehicle body (2); and a control unit (150) for performing straight traveling support to support automatic straight traveling of the traveling vehicle body (2) by controlling the steering device (110) based on the position information acquired by the position information acquisition device (120). The control unit (150) lowers at least a portion of the seedling planting unit (50) to prevent the tilt of the traveling vehicle body (2), when a tilt detection unit (180) detects that an upward posture of the traveling vehicle body (2) is more than a predetermined angle while executing the straight traveling support.SELECTED DRAWING: Figure 9

    【課題】自動直進走行の精度をより高めることのできる苗移植機を提供すること。【解決手段】操舵装置(110)により操舵される転舵輪(4)を備えた走行車体(2)と、走行車体(2)の後部に昇降自在に連結される苗植付部(50)と、走行車体(2)の位置情報を取得する位置情報取得装置(120)と、走行車体(2)の前後方向の傾きを検出する傾き検出部(180)と、位置情報取得装置(120)が取得した位置情報に基づき操舵装置(110)を制御して走行車体(2)の自動直進走行を支援する直進サポートを行う制御部(150)とを備える。制御部(150)は、直進サポートを実行中に、走行車体(2)の前上がり姿勢が所定角度以上であることを傾き検出部(180)が検出した場合、苗植付部(50)の少なくとも一部を下降させて、走行車体(2)の傾きを抑制する。【選択図】図9
