He has a tiller attachment for the back as well as a back blade attachment .He uses the back blade and the bucket fixing these people's rural private roads here, there's good money in that.
My brother-in-law does that. He has a box scraper for the back. That's what they use to resurface these gravel driveways. I paid some hillbilly kid $200 last year to do mine. Took him 10 minutes.
