Abstract
A high visibility coupler for front end loader implements that is selectively mountable to the extendable arms of a front end loader and is attachable to implements, such as a fork. The structure of the coupler is such that it has a plurality of parallel lift ribs that are perpendicularly interconnected by cross ribs to form an open lattice type structure, thereby allowing the operator of the front end loader to easily see and manipulate the fork or other attachment, so that the object to be picked up can be easily and safely engaged. One embodiment of the high visibility coupler for front end loaders includes a male master, a carriage and a movable implement such as a fork. The male master includes a plurality of parallel lift ribs that are perpendicularly interconnected by cross members to form an opening wherein the male master is received and carried by lift pistons operative with the lifting arms. The male master carries a carriage which has openings aligned with the opening of the male master. The carriage also has parallel ribs that are perpendicularly interconnected by cross tubes to form an open lattice type structure. One of the ribs includes a hook notch and carriage hol…
