Abstract
A coupler assembly for rotatably coupling a moldboard of a grader machine includes a bracket, a beam, a pin, a retainer, and an apparatus. The bracket is adapted to support the moldboard. The beam extends from a circle member rotatably coupled relative to a drawbar of the grader machine. The pin is adapted to rotatably couple the bracket and the beam to each other. Further, the pin defines an end adapted to extend outwardly from an assembly of the bracket and the beam. The retainer is adapted to be engaged with the end to retain the pin with the assembly of the beam and the bracket. Moreover, the retainer defines at least one end portion extending outwardly from the end. The apparatus is adapted to be mounted around the pin at the end to shield the at least one end portion of the retainer extending outwardly from the end.
