A backhoe-loader with a undercarriage resting on wheels and comprising at its front end a loader structure with a loader arm and a loading bucket and at the other end a superstructure revolving 360°, a driver cab is mounted to one side of the superstructure and on the other side next to the driver cab there are provided power units and a mounting pad pivotable about a vertical shaft for the horizontal pivot shaft of an excavator boom. The boom is positionable in a raised state with the dipper arm collapsed and the implement in a forward-pointing rest position above the undercarriage and outside the field of view of the driver cab. A front mudguard is present in front of the mounting pad and functions as a rest for the implement, the loader structure is mounted asymmetrically relatively to the longitudinal center axis of the undercarriage on the cab side of the undercarriage, and the rest for the implement on the front mudguard is widened toward the middle of the undercarriage.

An earthworking machine comprising: a) a mobile undercarriage adapted for movement over the ground, said undercarriage having a central longitudinal axis; b) a superstructure having first and second sides, said superstructure pivotally supported on said undercarriage for rotation relative thereto about a vertical axis; c) a loader assembly operable in a vertical plane, said loader assembly including a support frame having a central longitudinal axis, said loader assembly asymmetrically mounted to said undercarriage so that the central longitudinal axis of said support frame is substantially offset from the central longitudinal axis of said undercarriage towards said superstructure first side; d) a backhoe assembly mounted to a pivot means associated with said superstructure second side and adjacent said cab, said backhoe assembly including an extensible, articulating boom carrying an earthworking implement, said boom being personable into a stored position so that said boom and implement are positioned above said undercarriage and substantially out of the field of view of said cab; and e) rest means secured to said undercarriage and longitudinally aligned forward of said backhoe assembly, said rest means providing a storage area for said implement when said boom is in the stored position.
