PROBLEM TO BE SOLVED: To provide a tractor engine exhaust device capable of eliminating cause of making an engine malfunction upon blowing-up powder dust at a field by exhaust gas or preventing an operator from sucking powder dusts flown up by exhaust gas.SOLUTION: A tractor engine exhaust device of this invention in which exhaust gas of an engine E is discharged out to the surrounding atmosphere by an exhaust pipe 4 through a muffler 3 is constituted in such a way that there is provided an exhaust cover 6 enclosing in a cylindrical shape around a discharging port 4a of the exhaust pipe 4 and a cylindrical part direction of the exhaust cover 6 can be changed over in a vertical direction from a downward direction to a substantial horizontal direction. Additionally, the exhaust cover 6 is arranged at a front lower part of a vehicle frame 5 between the right and left front wheels 12. In addition, a lower cover 9 is arranged below the exhaust pipe 4 over a lateral width of the vehicle frame 5 and at the same time the fixing of the lower cover 9 is also used with a clamp 10 for supporting the exhaust pipe 4.

    【課題】本発明は、排気ガスが圃場の粉塵を吹き上げてエンジン不調の原因となったり、排気ガスによって舞い上がった粉塵を操縦者が吸い込んだりすることがないように出来るトラクタのエンジン排気装置とすることを課題とする。【解決手段】エンジンEの排気ガスをマフラー3を通して排気菅4で外気に排出するトラクタのエンジン排気装置において、排気菅4の排出口4aの周囲を筒状に囲む排気カバー6を設け、この排気カバー6の筒方向を下向きから略水平向きまで上下に変更可能にしたことを特徴とする。また、排気カバー6を車体フレーム5の前下部で左右前輪12の間に設けたことを特徴とする。また、排気菅4の下部に車体フレーム5の左右幅に亘って下カバー9を設けると共にこの下カバー9の取付を排気菅4を支持するクランプ10と共用したことを特徴とする。【選択図】図2
