Well, I guess that limits you to Cat, since Deere has not built a moter scraper in years, Terex never did build there own elevating scraper (they had an agreement with clark to use Hancock machines, and their bowls on some larger machines) and I don't even see scrapers listed on there website any more. For that matter since Hancock was bought out by Clark, and they were bought out by Volvo you could probaly get parts from a Volvo dealer, but I have not needed any parts that I could not get from our local Komatsu dealer, have not needed any parts for it at all really. Anyways, good luck with your search.
