PROBLEM TO BE SOLVED: To provide a high dumping type riding mower that facilitates lifting and opening/closing operations of a grass collecting container and quickly performs lifting and opening/closing motions.SOLUTION: The grass collecting container 9 is vertically lifted by a lifting arm 12, and an opening/closing cover 14 is constituted to be openable/closable. The lifting arm 12 is lifted by a lifting cylinder 13, and the opening/closing cover 14 is opened/closed by an opening/closing cylinder 15. An operating lever 33 is provided for operating the lifting cylinder 13 and the opening/closing cylinder 15, and the operating lever 33 is constituted to move along an operation guide. The operation guide includes a first operation guide 30 for operating the lifting cylinder 13 a second operation guide 31 for the opening/closing operation of the opening/closing cylinder 15 and a third operation guide 33 for operating the lifting cylinder and the opening/closing cylinder jointly.COPYRIGHT: (C)2013,JPO&INPIT【課題】所謂ハイダンプ式の乗用型芝刈機において、集草容器の昇降・開閉操作をし易くすることを課題とする。また、迅速に昇降・開閉動作を行なうことを課題とする。【解決手段】集草容器9は上下方向に昇降アーム12で昇降すると共に、開閉蓋14を開閉可能に構成し、昇降アーム12は昇降用シリンダ13で昇降する構成とし、開閉蓋14は開閉用シリンダ15で開閉する構成とし、昇降用シリンダ13及び開閉用シリンダ15を操作する操作レバー33を設け、操作レバー33は操作ガイドに沿って移動する構成とし、操作ガイドは昇降用シリンダ13を操作するための第一操作ガイド30と、開閉用シリンダ15を開閉するための第二操作ガイド31と、昇降用シリンダ及び開閉用シリンダを共に操作するための第三操作ガイド33を設けた。【選択図】 図5
