Well our tractor is not much different than a tractor built in 1974...the pump is not that different nor are the gears any different or bearings than a early 70s tractor.
I see your point, but if we're going by the JD303 spec which it lists I don't see the problem.

Take it back if your worried. If Hoye says it's fine it's fine. I would run it in mine. And I have loggers that are running that stuff in modern logging skidders.

Don't be. These things were designed simple for export to anywhere in the world. Any fluid available today that claims it meets/exceeds the outdated JD303 spec, is probably much better lubrication than what Yanmar designed these to run on. I don't recall we've ever read here of a UTF-related problem, ever.
Yanmar's manuals suggest a 5 minute warmup before moving the tractor. I doubt any of us do that, at least in mild weather. I think that was to allow time for the single-grade UTF to warm up and flow easily.
And a piece of trivia, from Soundguy (an early founder of this group and a YM1700 owner) - real JD303, along with the first ATF, contained whale oil. It is a superior lubricant but no longer available. So modern '303' UTF simply meets 303 performance specs but does that with different additives.
Soundguy is an engineer in a contracting company that runs millions of dollars of heavy earthmoving equipment. He says when equipment calls for 303-spec UTF that's what they use in those expensive hard working machines - same as what Clemsonfor sees in the professional logging equipment.
In summary, don't worry. Anything claimed 303 compatible is sufficient for these simple gear tractors. You could replace the fluid more frequently than the several-year intervals that most of us use if you are concerned about the quality of the fluid, or about contamination by dirt or water.

I think it's only Deere, not Yanmar, that advises to upgrade from 303 for tractors built after 1974. My manual for the 1980 YM240 explicitly states to use 303 and doesn't mention alternatives.

Why use a 4lb hammer when an 8lb will do. Thanks for the heads up on not having to remove the PTO housing am fixing the leak so when the fittings form Hoye come in I will get started installing the new loader.

Gah I'm so mad! Radiator and all will be here tomorrow but now I'll have to wait to run it until I get another seal! Oh well, got the other one out at least haha.
What do ya'll typically use to drive these seals in? My shop vac pipe fit perfectly!
And you're welcome haha! Drive it in SLOWLY!

I would probably get a piece of PVC to slip over the shaft to do it? or a shop vac pipe! haha
