Super A 3pt hitch and plow

Hard to tell from just a pile of parts. Assembled with a plow attached would be better. But it looks like one of those hitches that has the geometry botched to the point the lines of draft will be fouled. In other words, trying to use it to plow will likely be an unpleasant experience.
 
I agree with Jim! it dont look like it would work! 3-pt. plow has to have an EXACT geometry to it or it wont go in the ground or stay in the ground. ---- Make your own 3-pt! --- nuttin to it then you can fine tune it as you go. I made one for my cub and plow with it all the time with a Brinley 3-pt plow. GOTTA have several adjustments on the hitch and every patch has to be set for it cause that last patch was different, so you have to set it all the time while you plow.

how about using the factory fast hitch and plow, they work fine

That's because the system was designed by engineers with a slide rule and half a clue, not a guy with a stick welder and no clue :ROFLMAO:

If any of you remember Hugh McKay on yesterday's tractors, he had a design for a 3pt hitch that pulled off the fast hitch bail, and worked pretty well from what I understand...

That is a callback to the distant past. Hugh has been gone for over 15 years. But he cast a long shadow. You can still see his response on YT from when Matt asked about his hitch (with pictures). If you want to go searching for his posts, note that his name was spelled with two letters "a" in it, Hugh Mackay.

I never saw Hugh's hitch in action. But from the pictures it was pretty clear that it should outperform most of what you see on the web.

Sadly, I haven't taken the opportunity to try and recreate Hugh's system yet.

From the post Jim linked above:

The difference is the angle of the 3pt arms. In Hugh's version, you can see the 3pt arms are angled away from each other at the rear, and if you project an imaginary line from each arm, it comes together somewhere under the belly of the tractor.

On your typical aftermarket 3pt, the arms are attached directly to the final drives, so the 3pt arms are angled toward each other at the rear. When you project an imaginary line from each arm, they come together BEHIND the tractor.

Where those imaginary lines come together is your "point of draft" or point of pull. That's where all the forces converge. When it's under the tractor, the tractor controls the implement. When it's behind the tractor, the implement controls the tractor.
 
Homemade 3-pt hitches work fine IF you get the geometry right when you make them!!! Made several here for different models and all worked good.
