A construction machine apparatus includes a plurality of ground engaging supports (12A,12B), a machine frame (14) supported from the ground engaging supports and a milling drum (16) supported from the machine frame. A milling drum location detection system (42) is configured to determine a drum location in an external reference system (X,Y,Z). A location indicator system (50) includes a memory (52) configured to store information identifying a location of one or more areas A to be avoided in the external reference system, and a controller (48) configured to compare the drum location to the location of the one or more areas to be avoided, and to provide an output corresponding to a proximity of the milling drum (16) to the location of the one or more areas to be avoided (A1-7). |
