PROBLEM TO BE SOLVED: To provide a rice transplanter which has peripheral components such as a cooling system component and a powertrain component efficiently and compactly arranged around an engine while improving cooling efficiency.SOLUTION: A rice transplanter includes an engine 5 which is mounted in a traveling machine body, a transmission case which changes a speed of power of the engine 5 and transmits the power to traveling parts of the traveling machine body, and a seedling planting device which is attached to the traveling machine body. A suction fan for air-cooling the engine is provided on one lateral surface of the engine 5. The engine 5 is mounted on an engine base 57 which is mounted on the traveling machine body via a vibration-proofing member 58. A through-hole 108 facing a bottom surface of the engine 5 is formed in the engine base 57.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周りに効率よくコンパクトに配置した田植機を提供する。【解決手段】田植機は、走行機体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の走行部に伝達するミッションケースと、前記走行機体に装着された苗植付装置とを備える。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を設ける。前記走行機体に防振部材58を介して取り付けられたエンジン台57に、前記エンジン5を搭載する。前記エンジン台57には、前記エンジン5の底面に臨む抜き穴108を形成する。【選択図】図8
