To provide a work vehicle capable of reducing an operational load on an operator and improving workability.SOLUTION: A tractor is provided with a traveling machine body 1 to which a work machine 5 is connected so as to be lifted or lowered, an external hydraulic take-out device 10 for outputting working fluid to a hydraulic actuator (hydraulic cylinder 5c for inversion) of the work machine 5, and a control unit 25 for controlling a hydraulic output state of the external hydraulic take-out device 10. The external hydraulic take-out device 10 includes a plurality of external hydraulic ports A and B for outputting the working fluid. The control unit 25 includes external hydraulic automatic control means for controlling the hydraulic output state of the external hydraulic take-out device 10 on the basis of preset setting information when the work machine 5 is determined to have been lifted.SELECTED DRAWING: Figure 6 【課題】オペレータの操作負担を軽減し、作業性を向上できる作業車両を提供する。【解決手段】作業機５が昇降可能に連結される走行機体１と、作業機５が備える油圧アクチュエータ（反転用油圧シリンダ５ｃ）に作動油を出力する外部油圧取出装置１０と、外部油圧取出装置１０の油圧出力状態を制御する制御部２５と、を備えるトラクタであって、外部油圧取出装置１０は、作動油を出力する外部油圧ポートＡ、Ｂを複数備え、制御部２５は、作業機５が上昇したと判断したとき、外部油圧取出装置１０の油圧出力状態を予め設定された設定情報に基づいて制御する外部油圧自動制御手段を備える。【選択図】図６
