Some places do make a three point frame that can be attached to a chain harrow, or to a chain link fence for that matter I guess. I think that Northern Tool has them, and perhaps Tractor Supply, etc. I have a 4'x8' chain / spike harrow, and I have thought about getting the lifting frame. Mine works well in smoothing out landscape areas, wild boar rooting areas, etc., and I expect it would work well on manure, but haven't tried it since I don't have animals here.
I do think that the Coors tour is vital in this decision making process!
