The National Viking is a diesel ride-on scraper with an enclosed, climate-controlled cab and a 49.5 HP Kubota turbo diesel. National built it for extreme outdoor conditions and large-scale removal such as asphalt, bridge decks, runways and sports courts. It uses National's dual-lift front end and takes one, two or three tooling holders.
