Abstract
An excavating apparatus having a prime mover with a longitudinal centerline and a main frame (30) with an engine, a ground drive system and an excavation boom operatively attached thereto wherein the excavation boom has a sub-frame (112) with a first end and a second end. The first end of the sub-frame (112) is operatively pivotally attached to the main frame (30) along a main frame pivot axis (114). The main frame pivot axis is transverse to the longitudinal centerline of the prime mover. A head shaft (150) operatively rotatably attached to the second end of the sub-frame (112) along a head shaft axis (151) and the head shaft axis (151) is transverse to the longitudinal centerline of the prime mover. An excavating drum (148) is operatively attached to the head shaft (150) for rotation about the head shaft axis (151). The head shaft (150) is operatively pivotally attached to the second end of the sub-frame (112) along an axis (124) which is fixed with or parallel to a line (124a) which is fixed with respect to the main frame pivot axis (114) and which is substantially perpendicular to the main frame pivot axis (114) whereby the position of the head shaft axis (151) can be adjusted …
