PROBLEM TO BE SOLVED: To provide a walking type management machine enabling safe and efficient work.SOLUTION: A shift regulation device of a walking type management machine includes a handle capable of reversing an extension direction from a travelling machine body, a main shift lever provided on the travelling machine body, and a shift mechanism capable of switching travel power in accordance with the displacement of the main shift lever, and can regulate a shift operation of the main shift lever. In the device, regulation and deregulation of high-speed forward travel, high-speed backward travel and low-speed backward travel can be switched, the high-speed backward travel is deregulated in interlocking with the regulation of the high-speed forward travel, and a state where drive of a working machine and the regulation of the low-speed backward travel are interlocked with each other is switched to a state where they are not interlocked with each other.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2018,JPO&INPIT【課題】安全でかつ効率的な作業を可能とした歩行型管理機の提供。【解決手段】走行機体からの延出方向を反転可能なハンドルと、上記走行機体に設けられた主変速レバーと、主変速レバーの変位に応じて走行動力を切換え可能な変速機構と、を備え、上記主変速レバーの変速操作を規制し得る歩行型管理機の変速規制装置において、高速前進、高速後進及び低速後進の規制と規制解除との切換えを可能とし、高速前進の規制に連動して高速後進を規制解除すると共に、作業機の駆動と低速後進の規制が連動する状態から連動しない状態に切換える。【選択図】図6
