MOWER

To secure an installation space for a transmission mechanism regardless of lifting and lowering operation of a mower, stabilize a position of the mower in a lateral direction and reduce risk of damage of a member.SOLUTION: A mower 4 is suspended from and supported to a travel machine body through a link mechanism 36 so that it can be lifted and lowered, and a transmission mechanism 33 is provided on an upper side of a reaping blade housing 31 and transmits power to a reaping blade 32, and vertical extension parts 31A, 31B extending upward from a top surface of the reaping blade housing 31 are erected. A front side oscillation link 37A of the link mechanism 36 has one end which is coupled to the travel machine body so as to freely oscillate, and the other end which is coupled to an upper part of the front part side vertical extension part 31A so as to freely oscillate. A rear side oscillation link 37B of the link mechanism 36 has one end which is coupled to the travel machine body so as to freely oscillate, and the other end which is coupled to an upper part of the rear part side vertical extension part 31B so as to freely oscillate.SELECTED DRAWING: Figure 1 【課題】モーアの昇降操作にかかわらず伝動機構のための設置空間を確保することが可能でありながら、モーアの左右方向での位置の安定化を図り、部材の損傷のおそれを少なくすることが望まれていた。【解決手段】走行機体にリンク機構３６を介して昇降可能にモーア４が吊り下げ支持され、刈刃ハウジング３１の上側に位置して刈刃３２に動力を伝達する伝動機構３３が備えられ、刈刃ハウジング３１の上面から上方に延びる縦向き延設部３１Ａ，３１Ｂが立設され、リンク機構３６の前側の揺動リンク３７Ａは、一端が走行機体に揺動可能に連結されるとともに、他端が前部側の縦向き延設部３１Ａの上部に揺動可能に連結され、リンク機構３６の後側の揺動リンク３７Ｂは、一端が走行機体に揺動可能に連結されるとともに、他端が後部側の縦向き延設部３１Ｂの上部に揺動可能に連結されている。【選択図】図１
