PURPOSE:To simplify structure by integrating some power transmission systems into one power transmission system by interlockingly connecting each rotary shaft and constituting this transmission bendably at upper and near the shaft center. CONSTITUTION:A mower deck 8 equipped with a plurality of blades 11 and 12 in a row is arranged in the lower position of a vessel 2. A power transmission system 13 driving each of the blades 11 and 12 through rotary shafts 9 and 10 is arranged on the mowerdeck 8. Rotary shafts 9 and 10 are interlockingly connected to each other by the transmission system 13. This transmission system 13 is bendably constituted at upper and near the shaft center. Thus, structure can be simplified by integrating some power transmission systems, transmit power from the car body side to the transmission system on the mowerdeck into one power transmission system.
