Abstract
A visual reference system can be used with a loading machine such as a bucket loader having a bucket that can be vertically articulated with respect to a work surface. The visual reference system can include one or more illumination devices configured to project a visual fiducial beam toward the work surface. The visual fiducial beam can create a fiducial indication of where the bucket will contact the work surface when lowered adjacent the work surface. The visual reference system can assist in operation of the loading machine by enabling an operator to visually perceive the expected contact point between the bucket and work surface.
