Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a PTO control device of a work vehicle that can perform safe work travelling by a control system operated on the premise that an operator is seated on a driver's seat, and, furthermore, enables securing of safety when the operator is not seated, and a stable stationary operation of a PTO device by a simple operation.SOLUTION: A PTO control device of a work vehicle executes operation control for a PTO clutch 3a provided to a PTO device 3, and a travelling system clutch (11), and can execute stop control for an engine (2) when the time the operator is not seated on a driver's seat for a predetermined time by a seating sensor (5a) provided to the driver's seat (5). A stationary PTO operation implement (3b) for operating the PTO clutch (3a) is provided, and by this stationary PTO operation implement (3b), the transmission of the travelling system clutch (11) is regulated, and the stop of the engine (2) is regulated so as to achieve securing of safety when the operator is not seated, and stable stationary operation of the PTO device.SELECTED DRAWING: Figure 3 【課題】運転席への着席を前提として作動する制御システムによって安全な作業走行を可能とした上で、簡易な操作のみで、離席時の安全確保とＰＴＯ装置の安定した定置作動を可能とする作業車両のＰＴＯ制御装置を提供する。【解決手段】作業車両のＰＴＯ制御装置は、ＰＴＯ装置３に設けたＰＴＯクラッチ３ａと、走行系クラッチ（１１）とを作動制御するとともに、運転席(５)に設けた着座センサ(５ａ)による所定時間の離席継続時に前記エンジン(２)を停止制御可能に構成され、前記ＰＴＯクラッチ(３ａ)を作動させる定置ＰＴＯ操作具(３ｂ)を設け、この定置ＰＴＯ操作具(３ｂ)により、前記走行系クラッチ（１１）の伝動を規制するとともに、前記エンジン(２)の停止を規制することにより、離席時の安全確保とＰＴＯ装置の安定した定置作動を可能とするものである。【選択図】図３
