PROBLEM TO BE SOLVED: To provide a transmission case of a tractor, which allows a maker to easily remodel the tractor into a work vehicle dedicated to traction, allows the tractor, once sold as the work vehicle dedicated to traction, to be easily restored to a general tractor, and allows the tractor as the work vehicle dedicated to traction to sold at a low price.SOLUTION: In the transmission case of a tractor, a PTO shaft driving mechanism 75 is provided in the transmission case 8 which transmits driving force of an engine 5 to front wheels 2 and rear wheels 3 while changing speed, and a PTO output shaft 11, which extracts power from the PTO shaft driving mechanism 75 to the outside of the transmission case 8, is connected so as to be separatable and removal by sliding in a shaft direction in the transmission case 8. Further the transmission case of a tractor, with the PTO shaft driving mechanism 75 being provided with a PTO clutch 46 for intermitting the power of the PTO output shaft 11, is mounted on a work vehicle dedicated to traction.

    【課題】本発明では、メーカーでトラクターを牽引専用の作業車とする改造が容易で、一旦牽引専用作業車として販売した後に通常のトラクターに戻すことも容易で、牽引専用作業車としては販売価格を安く提供出来るようにすることを課題とする。【解決手段】エンジン5の駆動力を前輪2と後輪3に変速して伝動するミッションケース8内にPTO軸駆動機構75を設け、該PTO軸駆動機構75からミッションケース8外に動力を取り出すPTO出力軸11をミッションケース8内で軸方向にスライドして分離取外し可能に連結したことを特徴とするトラクターのミッションケースとする。また、PTO軸駆動機構75にPTO出力軸11の動力を断続するPTOクラッチ46を設けたままで牽引専用作業車に搭載することを特徴とするトラクターのミッションケースとする。【選択図】図3
