PROBLEM TO BE SOLVED: To provide a rice transplanter 1 which has peripheral components such as a cooling system component and a powertrain component efficiently and compactly arranged around an engine 5 while improving cooling efficiency.SOLUTION: A rice transplanter 1 includes: an engine 5 which is mounted in a traveling machine body 2 a transmission case 6 which changes a speed of power of the engine 5 and transmits the power to traveling parts 3 and 4 of the traveling machine body 2 and a seedling planting device 23 which is attached to the traveling machine body 2. A suction fan 71 for air-cooling the engine is provided on one lateral surface of the engine 5. The engine 5 is mounted in the traveling machine body 2 so that an output shaft 70 is directed in a right and left direction. An exhaust fan 91 is provided separately from the suction fan 71, on the other lateral surface, on the side opposite to the suction fan 71, of the engine 5. A shielding cover 88 surrounding the exhaust fan 91 is provided on the other lateral surface of the engine 5.COPYRIGHT: (C)2014,JPO&INPIT【課題】冷却効率を向上させつつ、冷却系部品や動力伝達系部品といった周辺部品をエンジン5周りに効率よくコンパクトに配置した田植機1を提供する。【解決手段】本願発明の田植機1は、走行機体2に搭載されたエンジン5と、前記エンジン5の動力を変速して前記走行機体2の走行部3,4に伝達するミッションケース6と、前記走行機体2に装着された苗植付装置23とを備える。前記エンジン5の一側面にエンジン空冷用の吸引ファン71を設ける。前記エンジン5は出力軸70を左右方向に向けて前記走行機体2に搭載する。前記エンジン5のうち前記吸引ファン71と反対側の他側面に、前記吸引ファン71とは別個に、排出ファン91を設ける。前記排出ファン91を囲う遮蔽カバー88を前記エンジン5の他側面に設ける。【選択図】図9
