But why won't I get any down pressure? Or, maybe a better question is how can you get down pressure? )</font>
You can't add down force, practically. Belarus & some retro-fit 3pt hitch conversions for old tractors offer down pressure.
90% of the time it is not practical for anything. Putting down force on the 3pt removes it from the rear wheels, so you'll just spin out anyhow. For something like a box blade or rear blade, either change the upper arm length, or add weights to the blade.
You would need to plumb in a hyd cylinder to a fixed upper point, and have it push down on the bottom 3pt arms. Extending or shortening the upper arm will have no effect on down-force, just as if you spun the upper link by hand now.
