  • Patent number: 6662478
    Abstract: In one embodiment, the present invention includes a grading blade disposed between a pair of holders. An adjusting mechanism is rigidly attached to the grading blade. A threaded connector is used to adjust the vertical position of the grading blade. Each holder is attached to a rear portion of a utility bucket, e.g., by welding. A plurality of gussets are attached to one of the holders and to the utility bucket, thereby providing further attachment and supported to the present grading assembly. The grading blade may be rotated, thereby using each of a pair of grading edges as desired. Moreover, the grading blade may be detached and repaired or replaced. When installed on a utility bucket, the present grading assembly allows precision grading to be conducted when driving in both forward and rearward directions.
