You mean a earth scraper, like they use building highways, only smaller? If that's what you're asking the answer is yes. I use to clean out ponds with one. Use a 50 hp tractor and it was a mechanical dump. It hooked to the arms and lowering the arms lowered the cutting blade and opened the front. You could adjust the depth of digging by adjusting the height of the arms. Once full, you raised arms and drove to dump site. The mechanical dump was a lever with a rope tied where you could reach it from the tractor seat. Pulled the rope and the front would drop down and dump the load. IIRC it held 3/4 or maybe 1 yd.
A friend had a hydraulic one that held 2 yds (IIRC) but he used a 100 hp tractor with duallies. I couldn't pull that rig with my tractor.

I watched a guy, his wife, and his helper use two pans with a couple of big tractors when they were building our pond. It was pretty impressive. He dug the main "channel"/middle section out and opened it up with equipment, cored the dam, then used the two tractors with pans attached to do big circles opening the sides and slowly dumping as they drove across the dam. He said the pans were the best way to pack a dam because of the weight they were carrying along with the small surface area of their tires. Also said it was the most efficient way to move the dirt. It looked like a turtle speed nascar race, just making circles while the pond got wider/deeper, and the dam got higher.
I'm sure they were a lot bigger than what you're talking about. Point above was I think they are most useful/efficient when you're moving dirt in a set pattern that doesn't require much intricate maneuvering.
Those big ones are common here building fish ponds and also precision leveling fields. My Dad built several Stock Ponds back in the 1950's using a 8N Ford and a "road scoop". I don't know what it held but not much. miles
