Bell 4206D - big scraper tractor

Not a name I was familiar with until I looked it up, Bell seems to be a primo tractor for those big off road scrapers. Usually fitted with wheels instead of treads, it hauls the Terra Titan  44 cubic yard, 110,000 pound scraper with hi arch gooseneck.
I don't see the scraper body around, I probably missed it. They would have arrived in Halifax by ship earlier this week.
