Is hydraulic fluid all the same?

[k0ua]

I know a few real farmers that have farms around my place (I am a fake farmer) and they buy the cheapest bulk hydraulic fluid they can find. Go figure.

That is because real farmers don't know anything about maintaining CUT tractors, and are all cheap "fellas" They wouldn't know a hydrostat from a fuel pump. Nor do they care. They are interested in saving money, and the cheap fluid will perform satisfactorily in geared tractors.

Won't argue one way or another on most of that. But HSTs have tighter tolerances than a geared machine and a lot of other hydraulics.
