ABSTRACT:
In an excavating apparatus including a bucket removably coupled to a distal end of a hydraulically powered boom, a field-detachable and field-attachable ripper comprises a shank portion having a lower tip, a mounting portion disposed along an upper area of the shank portion and a detachable and re-attachable coupling element disposed along the mounting portion. The detachable and re-attachable coupling element secures the ripper to the bucket. There is optionally further included a detachable ripper tip coupled to the lower tip. The detachable ripper tip comprises a metal piece having a point disposed at a first end thereof and having a hollow disposed at a second end thereof. The hollow is adapted to accommodate the lower tip therein. The detachable ripper tip further includes an opening disposed on one side thereof and extending into the hollow. The opening is adapted to accommodate a fastener extending from the side and into the lower tip. The fastener thereby detachably fastens the detachable ripper tip to the lower tip.
