Abstract
A heavy-duty scraping and rake attachment for excavator buckets for clearing brush-covered earth. The attachment is easily mountable to the bucket, thus avoiding the work and expense of removing the bucket from the arm. The scraper portion provides for offset toothed scrapers, a combination of toothed scraper and blade, and blade only use and is used in conjunction with a heavy-duty rake and power-operated thumb to grasp and remove the material rooted or scraped up from the earth by the scraper. The scraper portion and rake are included in a single unit, attachable and detachable from the excavator bucket. Scraper and blade attachments either detachably connected to the unit with bolts or permanently welded in place as desired.
