I respectfully disagree with your statement. When you drop the three point all the way down while using a box blade for instance, you would have the same negative force unless you set the hitch level to just touch the ground with the blade. Maybe I am wrong to run my box blade like that, but unless I am putting the finishing touches on a surface, I often drop the three point all the way.
That also begs the question of running the tractor in reverse, again using a box blade. I can easily visualize an upward force on the quick hitch. Again, I may be in error by doing that, but since my box blade has blades facing both forward and backward, I assume that is the reason for it.
So, unless the quick hitch manufacturer specifically addresses this type of operation, I have to assume there is no problem operating the equipment that way. Actually, there were no operating instructions at all enclosed with my quick hitch. Hopefully I have worded this post to correctly convey my thoughts.
All of that said, again, I am not blaming the manufacturer. I was simply trying to share my experience so that others might avoid a potentially serious accident.
Unless your 3PH actually has downward pressure, I can't see how your first paragraph would apply. My 3PH depends on the weight of the implement and gravity...no hydraulic or mechanical pressure at all ("float" in other words). That's simplifying things to a degree as some ground engaging implements "pull" (for lack of a better term) the implement in to the ground. Your box blade scarifiers for example.
However, running an implement on or in the ground isn't suspending them off a trailer and expecting the QH to hold them during transport.
Thinking about this, perhaps a better way to transport that implement would be to load it on the trailer first and rest the loader bucket on it. That would reduce the overall length of the tractor/implement and everything might fit on your trailer. That's speculation on my part, of course, since I've never seen your trailer, but I have seen guys do this on shorter trailers.
Just be glad those "near accidents" were just "near".
