Abstract
A method and apparatus for controllably preventing an implement from damaging a work machine or itself, which may occur if the implement strikes the work machine, by restricting the movement of the implement. A boundary is established a predetermined distance from the work machine. By controllably restricting the movement of the implement when it approaches the boundary, the implement is prevented from making contact with the work machine.
