Abstract: A wheeled work machine in which the center of gravity of a machine body is positioned low and the stability of the machine in a working position is secured without regard to the movement of the center of gravity caused by the rotation of a rotation table during work. An operation body (111) integrally rocking with a front axle case (96) is provided at the center in the left-right direction of the front axle case (96), and a rocking lock mechanism (112) for limiting the rocking of the operation body (111) is provided at a machine body frame (6). The rocking lock mechanism (112) has a lock cylinder (115) in which a piston rod (120) is horizontally fixed to the machine frame (6) and a switchover valve (118) for switching two oil chambers (124A, 124B) of the lock cylinder (115) between a communicated state and a closed state. A cylinder tube (116) of the lock cylinder (115) is operably connected to the operation body (111).
