PROBLEM TO BE SOLVED: To prevent an unnecessary engine stop caused by erroneously operating a forward/backward switching operation tool to a predetermined position for stopping an engine, while effectively preventing useless fuel consumption.SOLUTION: This engine stop operation structure of a working vehicle is constituted so as to stop the engine 7 based on predetermined operation of the forward/backward switching operation tool 40, and includes an operability different means A for making operability different from between an advance state and a retreat state when stopping the engine 7 by the predetermined operation of the operation tool 40.COPYRIGHT: (C)2013,JPO&INPIT【課題】無駄な燃料消費を効果的に防止しながら、前後進切り換え用の操作具をエンジン停止用の所定位置に誤操作することに起因した不必要なエンジン停止を防止する。【解決手段】前後進切り換え用の操作具40の所定の操作に基づいてエンジン7が停止するように構成した作業車のエンジン停止操作構造において、操作具40の所定の操作でエンジン7を停止させる際の操作性を前進状態からと後進状態からとで異ならせる操作性相違手段Aを備えてある。【選択図】図12
