Abstract: A circle assembly for supporting implement of motor grader is provided. The circle assembly rotates relative to drawbar about rotation axis. The circle assembly includes plate and rim member coupled to plate. The plate defines front section and rear section and includes a ring gear portion defining a plurality of teeth formed integrally therein. A first skirt portion and a second skirt portion integrally and contiguously extend from ring gear portion at rear section. The first skirt portion and second skirt portion are angled relative to ring gear portion in direction of rotation axis. The rim member includes first arm member and second arm member attached to first skirt portion and second skirt portion, respectively, and a circumferential belt portion extending between the first arm member and the second arm member. The belt portion is spaced from and surrounds ring gear member at the front section of the plate.

Abstract: A drawbar assembly for a motor grader is provided. The drawbar assembly defines a longitudinal axis and includes a first frame member and a second frame member. The first frame member is adapted to be movably coupled to main frame of the motor grader. The first frame member includes a first base member extending along longitudinal axis and a first mating portion bent away relative to first base member to extend transversely relative to longitudinal axis. The second frame member includes a second base member extending along longitudinal axis and a second mating portion bent away relative to second base member to extend transversely relative to longitudinal axis. The second mating portion is configured to mate with first mating portion to form a connection joint therebetween, facilitating the first frame member and second frame member to be conjoined to together support a circle assembly of the motor grader thereunder.

Abstract: A tilt bucket may include a front structure having an outer surface, the front structure including a base plate with a bottom surface. The tilt bucket may include a bottom edge and a curved wrapper extending between the base plate and the bottom edge. A ratio of a maximum distance between the curved wrapper and a first line extending from the bottom edge to the tangent point on the outer surface of the front structure, taken substantially perpendicularly from the first line, relative to a length of the first line, may be about 0.64 to 0.70.
