Those are expensive premium quality fluids, recommended if the Yanmar has PowerShift (A/T).

But YM180 is manual transmission. So anything from a reputable source labelled UTF, Universal Tractor Fluid, should be fine. The UTF from Tractor Supply is suitable.

Note UTF is thinner than gear oil. It's essentially hydraulic oil with additives, with viscosity like 20 weight motor oil. Because the fluid in the sump also serves the tractor's hydraulic system.

Update based on bmaverick's subsequent post, for anyone reading this in the future:

Tractor Supply's house brand 'Traveller Premium' is decent. Anything there labelled '303' brand doesn't meet present standards.

The normal Tractor Supply UTF has been under class action lawsuits in the past 5 years. It is worse than the very old John Deere 303 that is banned in several states.

Now, the Tractor Supply PREMIUM UTF works fine and so does the Kubota UTF.

Oh. Their 'Traveller Premium' is the only UTF I've seen with their trademark on it, in California. I didn't know they sold cheaper plain '303' claimed as UTF, also.

I haven't had a problem with the inexpensive Warren Industry (re-bottlers) '303' from Autozone. But the next time I flushed and replaced, I used TS Traveller Premium UTF just for peace of mind.
