ABSTRACT OF THE DISCLOSURE An earth-working machine such as an excavator includes a mobile chassis having a support base on which an internal or external gear is fixedly mounted. A slider ring is mounted on the underside of a turntable with a hydraulic motor mounted thereon and having a drive pinion held in mesh with the internal or external gear . A carriage supporting an excavating mechanism has an internal or external gear fixed to the underside of the carriage and rotatably mounted on an annular holder fixed to the turntable . An inter- mediate shaft is rotatably journalled in at least one bearing mounted on the turntable and has a pair of pinions fixed thereto and held in mesh with the gears , respectively. Alternatively, an intermediate shaft may have only the pinion held in driving mesh with the gear secured to the carriage and driven by another hydraulic motor mounted on the turntable through sprockets and a chain trained therearound. As a further alternative, another hydraulic motor is mounted on the turntable and has a pinion held in driving mesh with the gear on the carriage , and the pinions on the intermediate shaft may be disconnected by a clutch means .
