PROBLEM TO BE SOLVED: To realize a walking type mower having a light weight at a low cost by simplifying a mechanism for changing and regulating the mowing height of grass.SOLUTION: This walking type mower is constituted by supporting an engine part E on a traveling machine body 1 around a lateral axial alignment P1 so that the front side of a mowing blade 10 becomes a front down inclined posture of rocking in lower direction and also capable of freely changing the front down inclining angle &alpha of the mowing blade 10 in the front down inclined posture by changing the posture of the engine part E and mowing blade 10 integrally around the lateral axial alignment P1.COPYRIGHT: (C)2009,JPO&INPIT【課題】草の刈高さを変更調節する機構を簡素化し、歩行型草刈機の軽量化及び低コスト化を実現する。【解決手段】歩行型草刈機において、刈刃10の前側が下方に揺動した前下がり傾斜姿勢となるように、原動部Eを左右軸心P1周りで走行機体1に支持すると共に、原動部E及び刈刃10を一体で左右軸心P1周りに姿勢変更することにより、前下がり傾斜姿勢での刈刃10の前下がり傾斜角度αを変更自在に構成する。【選択図】図3
