Abstract
A regulator moldboard and grader blade assembly includes a moldboard having at least one transversely extending pin, the pin having a notch with a surface inclined toward the moldboard. At least one grader blade has at least one mounting opening having a flared surface complementary to the notch so that the blade is hangable on the pin so that the notch draws the blade against the moldboard as a fastener tightens the blade to the moldboard.
