PROBLEM TO BE SOLVED: To avoid occurrences of omission of an operation or misoperation of an operation lever by using a single operation lever and diversifying drive modes of a PTO clutch and a differential device.SOLUTION: A handling device of working machines includes: a differential device on a traveling system transmission mechanism; and a PTO clutch at a working system transmission mechanism for intermitting power transmission to the working device side. A single operation lever 4 for linking the differential device to the PTO clutch is configured to be switchable among a working position s3 for operating to enter the PTO clutch in a diff-lock state, a non-working travel position s1 of turning off the PTO clutch in a diff-lock release state, and a diff-lock non-working position s2 of turning off the PTO clutch in the diff-lock state.

    【課題】単一の操作レバーを用いて操作レバーの操作忘れや誤操作の発生を回避するとともに、PTOクラッチとデフ装置との駆動形態の多様化を図る。【解決手段】走行系伝動機構にデフ装置を備えるとともに、作業系伝動機構に作業装置側への動力伝達を断続するPTOクラッチを備え、デフ装置とPTOクラッチとに連係する単一の操作レバー4を、デフロック状態でPTOクラッチを入り操作する作業位置s3と、デフロック解除状態でPTOクラッチを切り操作する非作業走行位置s1と、デフロック状態でPTOクラッチを切り操作するデフロック非作業位置s2とに切換操作可能に構成してある。【選択図】図8
