The present invention addresses the problem of providing a rice planting machine (1) in which cooling efficiency is improved and peripheral components such as cooling system components and power transmission system components are arranged in an efficient and compact manner around an engine (5). The rice planting machine (1) of the present invention is provided with an engine (5) that is mounted on a traveling machine body (2), a transmission case (6) that changes the speed of power from the engine (5) and transmits said power to the traveling sections (3, 4) of the traveling machine body (2), and a seedling planting device (23) that is mounted on the traveling machine body (2). A suction fan (71) for engine cooling is provided on one side surface of the engine (5). On another side surface of the engine (5), said other side surface being on the opposite side of the engine (5) from the side on which the suction fan (71) is provided, an exhaust pipe (87) that is connected to the exhaust system of the engine (5) extends along one part of the other side surface, and a generator (94) is arranged on another part of the other side surface, so that an output shaft (70) protruding from the other side surface is sandwiched therebetween.La présente invention aborde le problème de fourniture dune machine permettant de planter du riz (1) qui est dotée dune efficacité de refroidissement améliorée et dont les composants périphériques tels que les composants du système de refroidissement et les composants du système de transmission de puissance sont agencés de façon efficace et compacte autour dun moteur (5).
