Jerusalem artichoke?

Seeing this along the perimeter of the farm, really noticeable since no other yellow blooms are out right now.

I would say not Jerusalem Artichoke. Although, there are over 70 species of wild sunflower, and they can even hybridize, which makes exact ID hard.

I'm going to guess its what I call Hairy Sunflower. I searched and found you a link to look at below.

Let me know what you think....

Very close match. I'm hoping to relocate some clumps of this into my NWSG stand.

It's not the JA that spreads on my property. The stems of mine have an angular cross section (not round) and leaves grow from one central stem.
I consider JA a troublesome weed. Gly will top kill it but it seems to colonize from an underground root system. It'll invade a clover plot if allowed to grow.
