Abstract: A work attachment for a motor grader includes a moldboard and a trip edge assembly coupled to the moldboard. The moldboard defines a plurality of first apertures. The trip edge assembly includes a trip edge structure. The trip edge assembly also includes a pivoting mechanism for pivoting a portion of the trip edge assembly in a first direction with respect to the moldboard when the trip edge assembly encounters an object in a drive path of the motor grader. The trip edge assembly further includes a mounting structure defining a plurality of second apertures. The plurality of second apertures are aligned with the plurality of first apertures to receive mechanical fasteners for removably coupling the trip edge assembly with the moldboard.

Abstract: A drawbar assembly for a motor grader is provided. The drawbar assembly includes a yoke plate, a backbar, a drawbar tube, and a sleeve. The yoke plate includes a first surface and a second surface. The backbar is attached to the first surface of the yoke plate. The backbar includes a tube facing surface. The drawbar tube includes a first end and a second end. The drawbar tube is attached to the first surface of the yoke plate, defining a clearance between the first end of the drawbar tube and the tube facing surface of the backbar. The sleeve encloses at least a portion of the drawbar tube. The sleeve includes a backbar attachment portion and a yoke attachment portion. The backbar attachment portion is attached to the tube facing surface of the backbar and the yoke attachment portion is attached to the first surface of the yoke plate.
