PROBLEM TO BE SOLVED: To provide a device for controlling the operation of a working vehicle in which a course of operations between engine starting and working is simplified.SOLUTION: The device for controlling the operation of a working vehicle includes: a traveling machine and a working machine which are driven by the output of an engine a working clutch freely switchable between an ON condition for transmitting the output of the engine to the working machine and an OFF condition for blocking the output of the engine and an accelerator for switching between an idling state for allowing the engine to run at the idling speed and a rated rotating state for allowing the engine to run at a rated rotation speed. The operation control device is provided with: an operation controller for operating the working clutch and the accelerator and an operation command unit that is a manual operation type, and for issuing an operation start command. When the operation command unit issues an operation start command to the operation controller, the controller puts the accelerator to the rated rotating state and the working clutch to the ON condition.COPYRIGHT: (C)2012,JPO&INPIT【課題】エンジンの始動状態から作業を行うときの操作の簡略化を図ることができる作業車の操作制御装置を提供する。【解決手段】エンジンの出力にて駆動される走行装置及び作業装置と、エンジンの出力を作業装置に伝達する入り状態と伝達を遮断する切り状態とに切り換え自在な作業クラッチと、エンジンをアイドリング回転速度で回転させるアイドリング状態と定格回転速度で回転させる定格回転状態とに切り換えるアクセル手段とが設けられた作業車の操作制御装置であって、作業クラッチ及びアクセル手段を操作する操作制御手段と、作業開始指令を指令する手動操作式の作業指令手段とが設けられ、操作制御手段が、作業指令手段にて作業開始指令が指令されると、アクセル手段を定格回転状態に操作し且つ作業クラッチを入り状態に操作するように構成されている。【選択図】図5
