Abstract: A compaction roller is provided for attachment to a backhoe or similar boom device mounted on a tractor for compacting loose fill dirt. The roller includes a closed cylinder mounted on a free wheeling axle having a plurality of radially extending teeth spaced about its circumference. A U-shaped attachment member is connected to both ends of the axle and is provided with two comb assemblies extending across the cylinder width having teeth spaced to clean the cylinder teeth as the cylinder rotates. The attachment member extends in a tapering U-shape to form a scraper blade integral with the attachment member for scraping fill dirt into a trench for compaction. Downward pressure is provided by the backhoe hydraulic piston assembly and the partial weight of the tractor at the backhoe is rotated over a section of fill dirt in the trench.
