WORK VEHICLE

To provide a work vehicle which can improve the braking property of the work vehicle when a test target does not function for a vehicle including a confirmation test function of soundness of a braking device.SOLUTION: A work vehicle 1 comprises: a drive source 21 which gives driving force; a first braking device 16 which brakes a front wheel 3 with friction force; a second braking device 17 which brakes a rear wheel 4 with friction force; a third braking device 18 which brakes the work vehicle; detectors 63, 64 which detect the travel state of the work vehicle; and control devices 70, 80 which control the drive source and the first to third braking devices. The control device drives the drive source in such a state that the braking device of the test target is operated when an execution operation of a confirmation test of the soundness is input with at least one of the first and second braking devices as the test target, determines whether the braking device of the test target is normal on the basis of the detection result of the detector, stops the output of the drive source when determining that the braking device of the test target is not normal, and operates the third braking device.SELECTED DRAWING: Figure 5 【課題】制動装置の健全性の確認テスト機能を備えた車両に関し、テスト対象が機能しないときの作業車両の制動性を向上できる作業車両を提供する。【解決手段】作業車両１は、駆動力を与える駆動源２１、前輪３を摩擦力により制動する第１の制動装置１６、後輪４を摩擦力により制動する第２の制動装置１７に加え、作業車両を制動する第３の制動装置１８、作業車両の走行状態を検出する検出器６３，６４、駆動源及び第１～３の制動装置を制御する制御装置７０，８０を備える。制御装置は、第１及び第２の制動装置の少なくとも一方をテスト対象としてその健全性の確認テストの実行操作が入力された場合、テスト対象の制動装置を作動させた状態で駆動源を駆動させ、検出器の検出結果に基づきテスト対象の制動装置が正常であるかを判定し、テスト対象の制動装置が正常でないと判定した場合に駆動源の出力を停止させると共に第３の制動装置を作動させる。【選択図】 図５
