Method and apparatus for monitoring and controlling an earthworking implement asit approaches a desired depth of cut

摘要

A method and apparatus (100) for determining the location of an earthworking implement (104) with respect to a desired depth of cut (106) between a layer of material to remove (108) and a layer of material to remain (110). As the earthworking implement (104) approaches or moves lower than the desired depth of cut (106), a control system (514) responsively stops movement of the implement (104) toward the desired depth of cut (106) or lifts the implement (104) from the material to remain (110).
