To enable stably stopping irrespective of a vehicle speed (travel speed).SOLUTION: A work vehicle includes: a travel clutch capable of switching between a connection state of transmitting power to a travel device, and a cutting state of cutting transmission of power to the travel device; a brake capable of braking the travel device according to the operation of a brake operation member; a control device capable of executing brake control of braking according to the operation of the brake operation member, and automatic switch control of switching the travel clutch from a connection state to a cutting state according to the operation of the brake operation member; and a switching member switching the automatic switch control valid or invalid. The control device performs first processing of operating the brake operation member when the automatic switch control is valid, and switching the travel clutch from a connection state to a cutting state when the vehicle speed of the travel device is less than a threshold value, and performs second processing of not switching the travel clutch from a connection state to a cutting state even upon the operation of the brake operation member when a vehicle speed of the travel device is equal to or more than a threshold value.SELECTED DRAWING: Figure 1

    【課題】車速(走行速度)に関わらず、安定して停止することができるようにする。【解決手段】作業車両は、走行装置に動力を伝達する接続状態と、走行装置への動力の伝達を切断する切断状態とに切り換え可能な走行クラッチと、制動操作部材の操作に応じて走行装置の制動が可能な制動装置と、制動操作部材の操作に応じて制動を行う制動制御と、制動操作部材の操作に応じて走行クラッチを接続状態から切断状態に切り換える自動切換制御とを実行可能な制御装置と、自動切換制御の有効又は無効を切り換える切換部材と、を備え、制御装置は、自動切換制御が有効である場合に制動操作部材の操作が行われ且つ走行装置の車速が閾値未満である場合には、走行クラッチを接続状態から切断状態に切り換える第1処理を行い、走行装置の車速が閾値以上である場合には、制動操作部材の操作が行われても走行クラッチを接続状態から切断状態に切り換えない第2処理を行う。【選択図】図1
