2076387 9117323 PCTABS00008 Certain earthworking vehicles are often provided with the ability to change work implements to enable them to perform a variety of operations. In many instances, the coupling mechanism between the work implement and the frame structure of the vehicle that supports them is designed such that the implements may be mounted and removed quickly. During the mounting of the implement upon the support frame, there is no means by which an operator can be sure that the proper attachment has been achieved. A visual inspection of the mounting apparatus or some sort of test maneuvering of the support frame is required to be sure the work implement is securely attached. The mounting apparatus of the present invention provides a means (84) by which a proper coupling between the work implement (10) and the support frame (13) is positively indicated. This indication can only be attained when the respective components are aligned in a manner that will allow a proper attachment.
