Abstract
An automatic object responsive control system for a work implement has a ground penetrating device mounted for sensing subsurface objects, an object detecting device for determining the undesirability of the object, and an implement control system for automatically elevationally raising the implement in response to an undesirable object being located elevationally between the implement and the ground penetrating device. The automatic object responsive control system is particularly suited for use on a geographic surface altering machine.
