PROBLEM TO BE SOLVED: To solve a problem which when a coolant sub tank of a radiator is disposed near an engine, a temperature of the sub tank is easily increased by radiation heat of the engine or the like and thus heat radiation effect is not expected in the sub tank itself.SOLUTION: In a tractor where a radiator is placed near an engine in an engine hood 2, a coolant sub tank 12 of the radiator is provided located near an inner surface of the engine hood in an upper end portion of a shroud. Further, an air bleeding hole 16 for bleeding air of a cooling circuit is provided in a portion of the engine hood 2 which corresponds to the sub tank 12. 【課題】ラジエータの冷却水用サブタンクがエンジンの近傍に配置されたものでは、エンジンの輻射熱等で温度が上がり易いため、サブタンク自体に放熱効果が期待できないことを解消する。【解決手段】ボンネット２内のエンジン近くにラジエータを配置してあるトラクタにおいて、ラジエータの冷却水用サブタンク１２をシュラウドの上端部位でボンネットの内面近くに配置して設け、前記ボンネット２のサブタンク１２に対応する部位には冷却回路のエアを抜くエア抜き穴１６を設けてあることを特徴とするトラクタの構成とする。【選択図】図３
