ABSTRACT:
A backhoe machine is disclosed wherein the entire articulated boom is mounted to a carriage for movement relative thereto about two normally generally horizontal pivot axes. The entire carriage is rotatable about a generally vertical axis to permit operation of the backhoe assembly laterally of the machine with the operator's station constantly facing the operation of the backhoe assembly. The first pivot axis for the articulated boom extends outwardly from the carriage and permits the entire boom to be canted relative to the carriage upon which it is mounted. The second pivot axis for the articulated boom is carried by a mounting frame and is rotatable about the first horizontal pivot axis to permit an extension of the articulated boom while being tilted relative to the carriage.
