PROBLEM TO BE SOLVED: To secure safety by restricting the rotation of a cut grass guide plate for covering a cut grass discharge port of a side discharge type mower to the lifting side.SOLUTION: In a riding-type lawn mower in which a side discharge type mower 5 is mounted on a lower side of a traveling vehicle, a cut grass guide plate 20 for covering a cut grass discharge port 19 of a mower cover 18 is provided so as to rotate around a rotary shaft 23 with respect to the mower cover 18, a standing member 21 is provided in which an outside surface 21a is formed on the mower cover 18 side. A stopper plate 25 is connected to the cut grass guide plate 20 so as to rotate, and an end surface 25a of the stopper plate 25 is provided so as to come into contact with the outside surface 21a of the standing member 21 in order to restrict the upward rotation of the cut grass guide plate 20 around the rotary shaft 23.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2020,JPO&INPIT【課題】サイドディスチャージ型モーアの刈草排出口を覆う刈草案内板の上昇側への回動を規制して安全性を確保する。【解決手段】走行車両の下方にサイドディスチャージ型モーア５を装着する乗用芝刈機において、モーアカバー１８の刈草排出口１９を覆う刈草案内板２０をモーアカバー１８に対して回動軸２３回りに回動可能に設け、モーアカバー１８側に外側面２１ａを形成した起立部材２１を備え、刈草案内板２０にストッパプレート２５を回動自在に連結し、刈草案内板２０の前記回動軸２３回りの上方回動を規制すべくストッパプレート２５の端面２５ａを前記起立部材２１の外側面２１ａに当接可能に設ける。【選択図】図５
