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