To reduce the number of detachment/attachment of the piping for supply and discharge of the pressurized oil to a hydraulic cylinder of a grass collection container side, and thereby perform detachment/attachment operation of the grass collection container by simple operation.SOLUTION: A riding mower includes a grass collection container 50 detachably supported to the ROPS (or a safety frame), and a plurality of hydraulic cylinders for making the grass collection container 50 perform the lifting/lowering operation and the posture change operation. In the pressurized oil supply/discharge paths to the plurality of hydraulic cylinders from a pressurized oil supply source carried by a traveling machine body 1 side, a solenoid valve 56 for pressurized oil supply and discharge to the plurality of hydraulic cylinders is supported to the detachable grass collection container 50, and a coupler 88 for detachment/attachment capable of connecting and disconnecting the pressurized oil supply/discharge path is provided between the pressurized oil supply source and the solenoid valve 56.SELECTED DRAWING: Figure 4 【課題】集草容器側の油圧シリンダに対する圧油の給排用配管の脱着本数を少なくして、簡便な操作で集草容器の脱着操作を行えるようにする。【解決手段】ロプスに対して脱着可能に支持される集草容器５０と、集草容器５０を昇降作動ならびに姿勢変更作動させる複数個の油圧シリンダと、を備え、走行機体１側に搭載されている圧油供給源から複数個の前記油圧シリンダに対する圧油給排路において、複数個の前記油圧シリンダに対する圧油給排用の電磁弁５６が、脱着可能な集草容器５０に支持され、圧油供給源と電磁弁５６との間に、圧油給排路を断接可能な脱着用のカプラ８８が設けられている。【選択図】図４
