Kioti CK4020 Transmission Fluids Recommendation

[ncridgerunner1]

Ordered a Kioti CK4020HSTSE this morning and have been looking at maintenance need for my machine in the future. I searched for compatible fluids but it seems most posts are 2018 or older.

On my Kubota it seemed only the Super UDT2 transmission fluid worked well. I downloaded the owner's manual and it lists Shell, BP and Exxon products but I'm not seeing universal fluids. Are the Kioti machines as picky about transmission fluid as Kubota.? What are you using that works well for late model CK models?

After owning 3 Kubota tractors over the years and a RTV, I am looking forward to receiving my first Kioti.

Any quality multi-pupose tractor transmission/hydraulic fluid will do a good job. Myself I use Cen-Pe-Co multi purpose. I have seriously considered Chevron Synthetic All-Weather THF.
You Kubota Super UDT2 is an excellent lube which would work fine.

Thanks! That's good to know.

I changed out my HST Kubota to Chevron multi-purpose fluid a few years ago and it developed a fairly loud transmission whine that got louder with increased speed. Immediately drained the system and went back to the UDT2 and the whine went away. Surprised me that my machine was so particular.

Since I use multi-purpose fluid on other machines, it is easier not to have to buy and store several different types.

After over thinking this on the NX4510HST, I went with Shell Rotella.
It's on its third full change out and second on the Rotella.
I did have on FEL cylinder leak. The guy that replaced the seal said it was due to high temps of heavy viscosity fluid.
Well, I rebuilt the cylinder about 6-7 months later, deciding I would not go to him again.
Turns out he only replaced the outer dust shield! The inner seal with the back up flat seal was deformed and not holding pressure.
Anyways, that lead me to conclude a defective seal NOT viscosity lead to the leak.
Tractor now has 1200 hours (2017 model) and over 800 hours on the Rotella.
When using owners manual, be prepared to follow rabbit trail of the latest updated nomenclature of the lubricants.
Kioti does not seem to update the manuals.
Images are horrible black and white of what looks like first production version of their product.
