PROBLEM TO BE SOLVED: To provide a working machine capable of facilitating the attachment of a working unit by performing rolling control so that the right and left inclining attitudes of a vertical link may always have a right and left horizontal attitude on removing the working unit attached to/detached from the vertical link capable of being lifted up and down and rolled right and left, and also providing safety work of attaching and detaching of the working unit to the vertical link. SOLUTION: In the working machine, the vertical link (51) is provided on the rear side of a traveling vehicle body, as capable of being lifted up and down and right and left rolling through a lifting up and down linking device (3) operated by a hydraulic cylinder and a rolling device operated by a rolling actuator. The working unit is attached through an attaching/detaching hitch (53) attached/detached to the vertical link (51). On detecting that the working unit is in a removed state by a detached state-detecting device (79), a controlling device for operating the rolling device into a predetermined reference state is provided.
