PROBLEM TO BE SOLVED: To prevent parking brakes from being in a single brake state.SOLUTION: Provided is a tractor which includes: right and left brake mechanisms capable of separately braking right and left rear wheels 5; right and left brake pedals 8R and 8L capable of separately or simultaneously brake-operating the right and left brake mechanisms; a pedal coupling operation tool 11 capable of selectively operating coupling/non-coupling of the right and left brake pedals 8R and 8L; and a parking brake lever 9 capable of locking the coupled right and left brake pedals 8R and 8L at a stepped-on position. Further, the tractor is provided with: a pedal coupling sensor 15 for detecting coupling/non-coupling of the right and left brake pedals 8R and 8L; a parking brake sensor 14 for detecting parking brake operation of the parking brake lever 9; and a control unit 13 for carrying out prescribed notification when parking brake operation is performed by the parking brake lever 9 in a state that the right and left brake pedals 8R and 8L are in a non-coupled state.SELECTED DRAWING: Figure 6

    【課題】駐車ブレーキが片ブレーキ状態になることを防止する。【解決手段】左右の後輪5を独立して制動可能な左右のブレーキ機構と、左右のブレーキ機構を独立又は同時に制動操作可能な左右のブレーキペダル8L、8Rと、左右のブレーキペダル8L、8Rの連結/非連結を選択的に操作可能なペダル連結操作具11と、連結された左右のブレーキペダル8L、8Rを踏み込み位置で係止操作可能な駐車ブレーキレバー9とを備えるトラクタであって、左右のブレーキペダル8L、8Rの連結/非連結を検出するペダル連結センサ15と、駐車ブレーキレバー9の駐車ブレーキ操作を検出する駐車ブレーキセンサ14と、左右のブレーキペダル8L、8Rが非連結の状態で、駐車ブレーキレバー9による駐車ブレーキ操作が行われた場合に所定の報知を行う制御部13とを備える。【選択図】図6
