I used a 5 yard scraper building a pond pulled by a 9000 Ford (130 HP) with dual rear tires. I was pulling it in medium clay soil and with 1000 pounds of weight on the front, ballast in the front and rear tires, it would pull the front tires off the ground loading it up.
That scraper in the photo wont be pulled by a CUT or even utility tractor except maybe down the highway or unless it is just picking up loose, dry sand and then it may overload the drawbar capacity.
