You need balast or you will trash your front axle!!!! really?

Besides...Balast is spelled with 2 'L's' not one.... Ballast....lol

I would like to make a distinction between "Ballast" and "counter weight".

Though the latter can serve as the former, Ballast is not sufficient to serve as counter weight.

Very true. I overloaded my 44hp tractor to the point I got paranoid about it and sold it before it gave me any problems. Replaced it with 95hp tractor. I reach it's limit more than a few times a year but not nearly as often as before.

One needs to be careful when using HP to define capacity. At 7200lbs with FEL and no additional weight added (no counterweight, no tire loading or wheel weights, no suitcase) my tractor is a 42 Hp. Built significantly heavier than competing models.

"Science , To the innocent, is no different than magic"

The "designers and engineers " will use the same principles as have been expressed in this thread. It's not rocket science! It's high school "physics".
Not everyone took the class, but they should have. ;-)

Pick up any "statics" text instructional literature. No need to embarrass one's self by calling in the experts.

But the engineers tasked with design of the front axle could supply the load value used in the consideration of all the design elements of the front axle for any of the popular models. They might even have a value for the margin of safety.
And then what? Load and acceleration computations to display a plot of If and Then statements that would defy comprehension, and validate common sense?

Bottom line, What question would you ask?

One question wouldnt do it, but answers to the following would help a lot:

...In relation to weight borne at specific wheel center distance, what is the working strength, proof strength, and breaking strength of the casting assembly?

In relation to thrust applied at specific wheel center, are those strengths the same?

...What wheel torque can be provided by the drive elements without failure; what component fails? How critical is turn angle?

..,,,,,Knowing these, and with a little analysis, a seat of the pants judgement could be applied to conditions validly.

That is very true. I used HP because I was responding to a comment that also used HP. Just trying to talk the language of the poster.

Kubota tends to be light for their HP. In my case I went from a 5000lb tractor to a 10,000lb tractor.

In contrast my 1984 Ford, 47HP, bare tractor weighs 5500lbs.

That failure was from side/forward/backward thrust. Probably from hitting something. Maybe a latent defect compounded it. ... Certainly not a counterweight issue.

Did you have the loader on craigslist a while ago.
I saw a loader for sale off a kabota and the front end was on jackstands and had no tire on it is why I ask

...No. ... Probably a bearing failure on that Kubot. They seem to be prone to those. A cage failure.

I apologize for using hp to describe tractor size because it annoys me as well. I really didn't need to use hp at all. My point was simply that one may be better off to go bigger (whatever that means for the application) and have margin than smaller (near minimum required to complete task).

The 4025 is a beast - a tribute to the days of heavy lower hp tractors.
