PROBLEM TO BE SOLVED: To provide an operation mechanism of a working vehicle capable of realizing the selected states of controlling modes corresponding to the state of a working ground, working form, etc., simply and surely even in the case that the states of the working ground, working form, etc., are not standard types.SOLUTION: This operation mechanism of the working vehicle is equipped with a multiple number of selective operation tools 49, 60, 74, 77, 81, 84, 93, 97, 98, 99 for switching the multiple number of controlling modes used selectively and corresponding controlling modes to a selected states that the uses are selected and the selection-released state of canceling the selections for the uses, and a single-package operation tool 103 switching the multiple number of controlling modes selected in advance to the selected states and selection-canceled states as the single package, and is constituted so as to change, by a prescribed renewal operation, the set of selected states of the expressed controlling modes based on the operation of the single-packaged operation tool 103 from standard selection states for selecting the multiple number of controlling modes selected in advance to optional selecting states for selecting the optionally selected multiple number of controlling modes.COPYRIGHT: (C)2008,JPO&INPIT【課題】 作業地の状態や作業形態などが標準的ではない場合でも、作業地の状態や作業形態などに対応した制御モードの選択状態を簡単かつ確実に現出できるようにする。【解決手段】 選択して使用される複数の制御モードと、対応する制御モードを、使用が選択された選択状態と、使用の選択が解除された選択解除状態とに切り換える複数の選択操作具49,60,74,77,81,84,93,97,98,99と、予め選定された複数の制御モードを一括して選択状態と選択解除状態とに切り換える単一の一括操作具103とを備え、所定の更新操作によって、一括操作具103の操作に基づいて現出される制御モードの選択状態が、予め選定された複数の制御モードを選択する標準選択状態から、任意に選定した複数の制御モードを選択する任意選択状態に設定変更されるように構成してある。【選択図】 図9
