To be able to lower the tip side loppus part in a storage posture while cutting grass containers in a raised discharge post while discharging cut grass from a grass collection container.SOLUTION: The Lopus 30 is provided with a pair of right and left base end side LOPS parts 31 and a tip end LOPS part 32. The distal end side rope portion 32 can change its attitude between the use posture erected with respect to the proximal side lobus portion 31 and the storage posture in which the distal side loppus portion 32 is laid down against the proximal side loppus portion 31 in the rearward direction of the traveling machine body. When the tip-side LOPS section 32 is in the storage posture and the grass collection container 10 is in the upward discharge posture, the free end side of the grass collection container 10 enters between the pair of left and right support column sections 33 of the front end side LOPS section 32.(FIG.【課題】集草容器を上昇排出姿勢にして集草容器から刈り草を排出できながら、格納姿勢にした先端側ロプス部を低く位置させることができるようにする。【解決手段】ロプス30は、左右一対の基端側ロプス部31と、先端側ロプス部32とを備えている。先端側ロプス部32は、基端側ロプス部31に対して起立した使用姿勢と、基端側ロプス部31に対して走行機体の後方向きに倒伏した格納姿勢とにわたって姿勢変更可能である。先端側ロプス部32が格納姿勢のとき、かつ、集草容器10が上昇排出姿勢のとき、集草容器10の遊端側が先端側ロプス部32の左右一対の支柱部33の間に入り込む。【選択図】図2
