Circle assembly for implement

Abstract

A circle assembly for an implement of a motor grader includes a circle and one or more mounting assemblies adapted to couple the circle with the implement. Each of the one or more mounting assemblies includes a first bracket coupled to the circle. The first bracket includes a first arm, a second arm axially spaced apart from the first arm, and a third arm connecting the first arm with the second arm. Each of the one or more mounting assemblies also includes a second bracket removably coupled to the first bracket. The second bracket is adapted to be coupled with the implement. Each of the one or more mounting assemblies further includes a fastener that removably couples the first bracket with the second bracket via the first arm and the second arm.

         8 . The circle assembly of  claim 1 , wherein the first bracket further includes a fourth arm spaced apart from the third arm and connecting the first arm with the second arm. 
     
     
         9 . An implement assembly for a motor grader, the implement assembly comprising:
 a circle assembly including:
 a circle; and 
 one or more mounting assemblies that couple the circle with the implement, each of the one or more mounting assemblies including:
 a first bracket coupled to the circle, wherein the first bracket includes a first arm, a second arm axially spaced apart from the first arm, and a third arm connecting the first arm with the second arm; 
 a second bracket removably coupled to the first bracket, wherein the second bracket is coupled with the implement; and 
 a fastener that removably couples the first bracket with the second bracket via the first arm and the second arm, wherein, when the fastener is coupled with the first bracket and the second bracket, a portion of the second bracket is axially disposed between the first arm and the second arm; 
 a cylinder coupled, at a first end, with the first bracket and coupled, at a second end, with the second bracket; and 
 
   an implement removably coupled with the circle assembly.   
     
     
         10 . The implement assembly of  claim 9 , wherein the first bracket further includes a first bushing coupled to the first arm, and wherein, when the fastener is coupled with the first bracket and the second bracket, the fastener is at least partially disposed in the first bushing. 
     
     
         11 . The implement assembly of  claim 10 , wherein each of the one or more mounting assemblies further includes a first bearing radially disposed between the first bushing and the fastener. 
     
     
         12 .
