I've used the Beltecs and they are extremely efficient at what they are made to do.
The one I used was designed to attach to the 3 point though. It would lift the tractor off the ground easily and when cracking rock you could see the ground lifting several feet from the hole when grabbing chucks of limestone. It will also run through a water main like butter
By design, the heavier the tractor is the better it will work. The cheap augers have a tough time even in clay IME. Making some custom teeth with help, but they wear fast and will need to be replaced.
