So anyone who disagrees with you is arguing. how about open minded enough to research and see that Kubota is not the only oil that is quality.Sam, did you come to this forum just to argue? Use what ever oil you prefer, you don't need our permission. You don't believe folk who work on Kubota tractor for a living, and you say, " ... sounds like a story to me".
Maybe go to a different tractor brand and peddle your opinion. Surely you can find someone broke enough to buy off brand products after they bought a nice tractor.
So the other oils that are made for HST transmissions for all the other company's tractors must be garbage according to who?
there are other tractor manufactures that make HST tractors and use there own and other brands that are made from the oil manufactures... So it makes sense that there are other oil manufactures that make and sell quality HST oils... I know for some this may be difficult to comprehend, but it is reality.
