ABSTRACT:
A mechanism for mounting an earthworking implement such as a backhoe apparatus to a mobile frame of an off-highway machine. The mounting mechanism includes a support attachment that is connected to the frame for movement about a generally vertical pivot axis. The earthworking implement is carried by, and thus, movable with the support attachment. First and second drivers move the support attachment and thereby the earthworking implement in opposite directions relative to each other. Each driver has one end articulately connected to the machine frame and a second end connected to the support attachment by a pin aligning a second generally vertical axis that extends generally parallel to the pivot axis of the support attachment. A self-aligning bearing is captively carried by and between the second end and a respective pin of each driver to compensate for vertical misalignment between the first and second vertical axes without substantially increasing the distance the pivot axis is disposed away from the frame.
