Anybody ever heard of or use a Hancock elevating pull scraper. My friend has told me about one for sale and we are probably going to go in halves on it. I still have yet to see it, maybe this week. Apparently the paddles are pto driven, but the rest is hydraulic. I don't know what size it is but it sounds like a d4 would be a good sized tractor to pull it, but I would need a pto output regardless of size tractor. What's your thoughts?
