Abstract
In some implementations, coupling system for rotatably coupling a moldboard of a snow wing assembly includes a hinge for rotatably coupling the moldboard to a linkage assembly to enable the moldboard to rotate in a first rotational direction, the hinge including a plate having a first face and a second face. The plate includes a first passageway extending between the first face and the second face to facilitate lubricant being supplied to a first interface between the plate and the moldboard. The coupling system may include a pin extending through the moldboard and the plate to rotatably couple the moldboard with the hinge. The pin enables the moldboard to rotate in a second rotational direction about a rotational axis defined by a body of the pin, and the body includes a second passageway extending from a bottom portion of the pin to an outer surface of the pin.
