PROBLEM TO BE SOLVED: To provide a seedling transplanter for preventing the occurrence of an unexpected situation by preventing three travel modes (a road running mode, a planting-speed running mode and a neutral mode (PTO)) from being interchanged during running of a car body even if an auxiliary speed change gear is operated, thereby to prevent the occurrence of an unexpected situation.SOLUTION: The seedling transplanter comprises: an electric motor 16b for interchanging three travel modes (i.e., a road mode, a planting speed mode and a neutral mode) of an auxiliary speed change lever 16 and a PTO shifter 16c for regulating the operation of an auxiliary speed change lever 16, whereby the three running modes are not changed during the running of a car body 2 thereby to prevent the auxiliary speed change lever 16 from being operated by the contact of the foot or the like of an operator and to prevent the running car body 2 from being suddenly stopped or decelerated.COPYRIGHT: (C)2014,JPO&INPIT【課題】走行車体が走行中は、副変速レバーを操作しても3つの走行モード(路上走行モード、植付速走行モード及び中立(PTO)モード)が切り替わらないようにして不測の事態の発生を防ぐ苗移植機を提供すること。【解決手段】副変速レバー16の3つの走行モード(路上モード、植付速モード及び中立モードに切り替える電動モータ16bと車体2の走行中は副変速レバー16の操作を規制するPTOシフタ16cを設け、車体2が走行中は、副変速レバー16を操作しても前記3つの走行モードが切り替わらないので、オペレータの足等が接触して副変速レバー16が操作され、走行車体2が急停止したり急減速したりすることを防止できる。【選択図】図5
