A friend of mine works for a forklift repair company and came up with a set from an old forklift. He built mounts to fit his loader, added an extra control valve to control them, and it worked like a charm. The only downside that I saw was that the set weighed about 300 pounds. With his 65 hp tractor, it didn't make much difference, but on a smaller tractor, it could make a big difference.
