Abstract: A circle and beam assembly for a motor grader. The circle and beam assembly of the present invention includes a circle from which two beams extend wherein the beams are oppositely disposed. An opening is defined at the lower end of each beam. A hinge rod is received through the openings, and the hinge rod extends beyond each of the beams for receiving a grader blade thereon. The outer diameter of the hinge rod is slightly larger than the diameter of each opening. Each opening is heated to permit the hinge rod to slide therethrough such that upon cooling, the hinge rod is securely held.

Abstract: An improved grader circle for reinforcing the outer surface of a circle. The improved grader circle assembly of the present invention includes a circle defining an outer surface from which two vertical beams extend in an opposing manner. A front reinforcement plate is welded to the outer surface of the circle at a front portion thereof and the front reinforcement plate extends between the first ends of each of the vertical beams. Two rear reinforcement plates are welded to the outer surface of the circle at a rear thereof, one each between the second ends of the vertical beams and the tip cylinder bracket.
