Hydraulic/ Hydrostat oil?

[L47TLBwannabe]

What are people using for oil? I couldn't get a straight answer out of the dealer I just did my break in oil change for the engine and I'd like to replace the hydraulic and hydrostatic oil filters but I know I'll have to top it off but don't know what exactly to get. The excavators I run at work have AW32 oil full synthetic I believe. The dealer had told me to ask the guys at Piston Ring since that's where they bought it from but Piston Ring wasn't sure what the dealer had put in my tractor. I'll give them all heck on Monday (naturally) but I have some decent weather finally so I can do all my servicing before it gets cold again as I can't get in the garage door with how tall the cab is. lol

Whatever you get, look for the Deere J20C, J20D, or the Kubota SUDT or SUDT2 rating.
Any of those should be fine for hydrostatic transmissions, wet brakes, wet clutches and other modern niceties.

The performance of J20C hy-guard is terrible in cold weather. J20D is low-vis hy-guard, and is much easier to get going when things are less than 40°F. It blows my mind how one bucket of aftermarket oil can cover both. I can't say for sure about Kabota, I've not owned one long enough to consider a fluid change.

Kubota SUDT is similar to JD J20C.
Kubota SUDT2 is similar to JD J20D.

Most buckets will just list Kubota UDT, Kubota SUDT and JD J20C.

Manual states: Transmission Fluid - DAEDONG: UTF55 or SHELL: Donax-TD or EXXON-MOBIL: Mobilfluid 424, Exxon Hydraul 560 or BP: Tractran UTH Capacity is 5.8 gals or 22.0 L...........

Looking at a couple of those, the Mobilfluid 424, Exxon Hydraul 560 and the Donax-TD all meet the Deere J20D and the Kubota UDT standards.
The Donax-TD claims to meet or exceed both J20C and J20D.

Donax TD is now Spirax S4 TXM which is the same as the Rotella HD tractor transmission and hydraulic fluid. I believe it is considered a 10w30 multigrade hydraulic oil.

Interesting, Spirax S4 TXM claims to meet JD J20C, but not J20D and the page for it does not claim to meet any Kubota specifications.

When I topped mine off after changing the filters, I used the 424, and haven't noticed any change in operation, even in cold temps. I'd heard others say it could make the HST "whine" a bit more in the cold, but I only needed about a gallon, so probably not enough to have much effect. When the time comes to change all of the fluid, I plan on using the Kubota SUDT2, as I've heard that it's one of the best in cold temps.

The bucket of Spirax that I have shows J20C and doesn't show Kubota UDT. The bucket of Rotella HD tractor hydraulic fluid shows Kubota UDT and JD20A,B,C,D also mentioned on the Spirax bucket is it is 10w30 oil

And then there is this at the "tractor" store:

Interesting, I wonder how they meet the 303 spec which requires whale oil

Properly be fairly good for dust control!!!!!!

Good day from a fellow Canadian. With temps in my area hitting minus 35 Celsius or lower I went with a Co-op tractor hydraulic fluid Super T-HF synthetic blend that has a pour point of -60 Celsius and meets all the specs listed. The price is reasonable and now with 200 hours on it, no complaints. The biggest issue in the winter is getting up to temp when it is cold, and on initial startup this fluid seems to flow ok. Have not tried any of the others listed.

Here is a link to the specs.

I use Mobile 424 it has a pour point of -42

I was using TSC's traveller premium. I was getting whine with the hst in the winter. Switched to the Mobil and it's gone. A local fleet farm sotre carries it in 5 gallon pails.

I have switch over a couple of machines to Shaeffer Oil's 315 Simplex Supreme & have been very happy with both the cold & warm weather performance (much better performance in cold weather) .... probably not the cheapest (not more than any other good fluid) but I don't have that many pieces of equipment that I need to change the fluids on so to me it has been worth it... Have switched to their grease also & find I'm using a lot less with almost zero wash / bleed out... going to be moving over to their engine oils for everything as soon as I use up the Amsoil I have in stock.... Just something to look at....

I will keep that in mind I don't plan on working in our infamous -40 weather often jokingly referred to as a 'Hudson Bay Chinook' when the wind whips up over Hudson Bay by Churchill, MB.

I just went to NAPA and ordered a 5 gal bucket of Coastal full synthetic THF and it works just fine in cold weather. I bought a gallon of Kubota full synthetic to top it off if needed.

I'm very happy using AMSOIL Tractor/Hydraulic oil in my Kioti. I have nearly 300 hours on this oil so far and it works well in the cold with almost summer-like characteristics right from a cold start. I can blow snow in -25C, within only a couple minutes after a cold start, and the hydraulics think that it's summer weather. Covers the JD, Kubota specs and many others. Dutchy
