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.
