Before going to look at a Ford 10' offset disk I would like an opinion if my 83 hp 4wd tractor is enough?

With it being 4WD I think you will be o.k but I guarantee you it will be all it wants. Do you know what size the disc blades are?

It should be fine. My 70 HP tractor pulls an 8' offset set wide open quite easily. I used to have a L3650 (36 HP) that would pull it in 4WD and low range.
Besides, you can always gear down and take your time.

The width of the Disc Harrow does not relate well to the draft force generated in pulling.
The important metrics are PAN DIAMETER, (A=πr2), where the weight is, and the NUMBER of pans.
Third is pan thickness, a spec hard to come by. However, proportionally, thickness does not vary like pan diameter.

Not all offsets are created equal. Some are super heavy and aggresive and designed as primary tillage tools. I have thought of a 10-12' offset but wonder if my 135 HP 4440 with duals will pull it. Some it would I am sure but some it wouldn't.

Here's one at 992lbs per disk. Can be had in 9'-12' working widths. Something tells me that your tractor isn't quite enough.

I bought the disk, good bad or ugly. It has 24" stubbles on the front and 24" smooth on the rear. I have used a 9' offset drag with 20s all around and it pulled it like going through butter in 4x4. With the gauge wheels isn't up to the operator to set depth so you don't over work the tractor?

I think you should be able to pull it with wheels full up with 83 HP (is this drawbar or engine?) but design of the disk and soil type is critical to how much power it takes. I remember John Deere made an offset disk back in the 60-70s that was hard as heck to pull due to the shape of the disc, they were radically cupped but then transitioned to flat at about a 6-8" radius at the axle. They seemed to require 20+ HP more to pull them compared to a concentrically shaped disc but they would turn over the dirt at super slow speed whereas as a normally cupped blade had to have twice the speed to turn the soil over.
