I have a ford 641. I was grading the lane like I do often. The
tractor started to knock so hard the entire trActor shook and
died. I towed it back to the shed. It will turn over but it knocks
so bad. It sounds like the knock is under the hood, but it
shook so hard it even shook the seat. Any ideas what is
going on with it?

Last time I had that it was a spun rod bearing. I don't know if that's your issue but your description is not of something that's an easy fix.

I?m sure it is an expensive fix whatever it is. Thanks for your
response.

If it shakes the tractor, it's either a broken crankshaft, or at the flywheel.

Unfortunately the only thing to do is start taking it apart and see what's broken :(

I would be on the hunt for a used motor, either a 134 or a 172. If you share your location you can get suggestions on where to look.
