I recently bought a Kubota L3710 GST tractor. I want to change all the fluids so I know their clean. What is everyone running in their GST transmissions?

Depends a bit on climate. SUDT and UDT are both supported. SUDT much better if you get very hot or very cold. In a milder climate, UDT seems fine. All Kubotas in NZ seem to come with UDT, and SUDT seems hard to come by.

The manual says Super UDT. I use SUDT2 in mine, I think it's all my dealers carry.
