Alan,  Allis Chalmers tractor use a big spring on the snap coupler
down under the tractor or a rock shaft on the lower arms of their
three point hitch tractors.

As far as I know all the load & depth, or draft, regulating systems get all
their input from the top link connection.  I think that with a semi-mounted
plow there is no way for anything to be "seen" by the tractor sensing magic
since there is no top link used.

I'm not sure you would be all that busy.  From what I remember seeing when
others were plowing with semi-mounteds, is that lift & lower is done in
stages.  To get the plow in the ground, drop the front by just stuffing the
3-pt control down to a preset stop then drop the rear, pretty much as soon
as you can get your hand on the second lever.  To raise, life the front
first, then the rear.  Probably not as much of an issue with only four
bottoms but on the really big plows it looks like that would tend to shorten
the headlands a bit as well.
