alchemy,
Since you mentioned something about about a loader in your first post, I thought we were talking about a loader valve.
Most all 3pt system have float as most don't have down pressure and therefore the T-N-T system, which will give down force.
My fault, I think I was going back and forth with loader and 3 point. I've never used a loader yet but was trying to understand float by my experinces with the 3 point.
