PROBLEM TO BE SOLVED: To stop a travelling vehicle body safely even if a defect occurs in a braking mechanism.SOLUTION: The work vehicle comprises: a power transmission device (D) having a travelling vehicle body (1a), an engine (E), and a clutch member (48) which is supported to be movable between a transmission position for transmitting power from the engine (E) and a shut-off position for shutting off the power a braking device (301) braking control means (CA4) which moves the clutch member (48) to the shut-off position and activates the braking device (301) when braking the vehicle body braking determining means (CA4b, CA4c) which determines whether or not the vehicle body is braked when activating the braking device (301) and engine control means (CB2) which stops the engine (E) when determining that the travelling vehicle body (1a) is not braked based on determined results by the braking determining means (CA4b, CA4c).SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】制動する機構に不具合が生じても安全に走行車体を停止させること。【解決手段】 走行車体(1a)と、エンジン(E)と、エンジン(E)からの動力を伝達する伝達位置と遮断する遮断位置との間を移動可能に支持されたクラッチ部材(48)を有する動力伝達装置(D)と、制動装置(301)と、制動する場合にクラッチ部材(48)を遮断位置に移動させると共に制動装置(301)を作動させる制動制御手段(CA4)と、制動装置(301)を作動させた場合に制動されたか否かを判別する制動判別手段(CA4b,CA4c)と、制動判別手段(CA4b,CA4c)の判別結果に基づいて走行車体(1a)が制動されていない場合にエンジン(E)を停止させるエンジン制御手段(CB2)と、を備えたことを特徴とする作業車両。【選択図】図3
