PURPOSE:To facilitate the installation and removal of an engine in a ride-on type mowing working vehicle, by horizontally laying a water cooled type cooler so that the latter is supported to a vertical shaft type engine thereabove, and by arranging a cooling fan between the engine and the cooler. CONSTITUTION:In an arrangement applied in a small type ride-on mowing working vehicle, a V-shape engine 2 is arranged such that its crankshaft 3 is laid in the vertical direction, and a pulley for driving a mowing machine A is attached to one end of the crankshaft projected downward from a vehicle body frame 1. Further, an axial flow type cooling fan 9 is attached to the other end of the crankshaft 3 vertically projected upward. Front and rear steys 14, 15 are planted on the top of crankcasing 13 of an engine 2, and a cooler 16 is horizontally laid between the upper ends of the steys 14, 15. Further, a fan duct 19 surrounding the cooling fan 19 is projected from the bottom of the cooler 16, and a cooling air inlet port 21 and a cooling air take-out port 22 are formed in the top surface wall 20A and front surface wall 20B of a bonnet 20, respectively. |
