PROBLEM TO BE SOLVED: To provide a rice transplanter capable of identifying the operation position of an inter-seedling speed changing lever for operating an inter-seedling speed changing device and the operation position of an operation lever for operating a power transmission switchover mechanism.SOLUTION: On a first power transmission shaft 43, a sparse planting side gear set 70 and a dense planting side gear set 71 are arranged at a predetermined interval, and an inter-seedling speed changing gear 72, which selectively engages with the sparse planting side gear set 70 and the dense planting side gear set 71 in a manner sliding in an axial direction of a second power transmission shaft 46, forms a neutral position that cuts off power transmission between an engine 15 and a transplanting work machine 9 at the predetermined interval where the inter-seedling speed changing gear 72 engages with neither the gear set 70 nor the gear set 71. With respect to the neutral position, tilting an inter-seedling speed changing lever 75 to one side selects a wide inter-seedling space (inter-seedling space for sparse planting) and tilting the inter-seedling speed changing lever 75 to the other side selects a standard inter-seedling space (inter-seedling space for dense planting).COPYRIGHT: (C)2014,JPO&INPIT【課題】株間変速装置を操作する株間変速レバーと伝動切換機構を操作する操作レバーの操作位置を識別可能な田植機を提供する。【解決手段】第1の伝動軸43に所定間隔を開けて疎植側ギヤ組70及び密植側ギヤ組71を配置し、第2の伝動軸46の軸方向にシフトして疎植側ギヤ組70及び密植側ギヤ組71と選択的に噛合する前記株間変速ギヤ72が、これらギヤ組70,71の両方と噛合しない前記所定間隔において、エンジン15と植付作業機9との間の動力伝達を遮断するニュートラル位置を構成する。該ニュートラル位置を基準にして、株間変速レバーを一方側に傾倒すると広株間(疎植株間)、他方側に傾倒すると標準株間(密植株間)に設定される。【選択図】図4
