PROBLEM TO BE SOLVED: To provide a tractor capable of stopping a machine body without stopping an operation of an engine only through a pedal handling of a brake pedal.SOLUTION: A tractor 1 comprises: a hydraulic stepless speed variator 8; a brake control ON-OFF switch 29; and a controller 3. The hydraulic stepless speed variator 8 transmits a driving force got from an engine 7 to rear wheels 5. The brake control ON-OFF switch 29 switches over between an operation and non-operation of a brake stop control mode for stopping a machine body through operation of a brake pedal 21. The controller 3 sets a trunnion arm 62 of the hydraulic stepless speed variator 8 to its neutral position when a pedal operation of the brake pedal 21 is detected during the brake stop control mode. 【課題】ブレーキペダルのペダル操作のみによりエンジンを停止させることなく、機体を停止することができるトラクタを提供すること。【解決手段】トラクタ１は油圧無段変速装置８とブレーキ制御入切スイッチ２９とコントローラ３とを備える。油圧無段変速装置８はエンジン７からの駆動力を後輪５に伝達する。ブレーキ制御入切スイッチ２９はブレーキペダル２１を操作して機体を停止させるブレーキ停止制御モードの実行、非実行を切り換える。コントローラ３はブレーキ停止制御モードを実行しているとブレーキペダル２１のペダル操作を検出すると油圧無段変速装置８のトラニオンアーム６２を中立位置にする。【選択図】図９
