Swapping attachments with hydraulic fluids? Any concerns?

[number two]

Hmm?
Your current fluid may meet both specs?
Surely,your JD HST fluid should suffice for your gear Kubota.
What's in the L3130 now?

Good Luck!

Thanks for your response. I'm not sure about fluid specs, as companies tend to conflate marketing claims with specs. The John Deere 1025R is fairly new so I've only done one transmission fluid change on it so far. I was in a hurry so didn't research options and just spent the $$$ on John Deere Hy-Gard oil so that's what's in the Deere. John Deere seems very careful to avoid any statements about what Hy-Gard actually is, preferring to make us think it's made with magic pixie dust from fairies who only work for John Deere.

The Kubota is due for a hydraulic filter change and top up. I don't remember what went in there last time, but this time my wife bought a 20L pail of Premium UDT and that's what's about to go in there.

I did find https://jdparts.deere.com/partsmkt/unsecured/document/english/featbene/hygardsalesbrochure.pdf which states that according to John Deere, Hygard can be used where UDT is specified. So presumably both tractors could use either Hygard or Super UDT just fine. Not sure whether it's OK to mix them (I'd tend to think yes but I'm not a chemical engineer) but I suppose I could flush the Deere and put Super UDT in that too.

Thoughts from anyone knowledgeable on having those two oils in the separate tractors, mixing through the shared trailer, vs. flushing the Deere and putting Kubota Premium UDT in that?

As far as I'm concerned worrying about fluid differences on any tractor or skidsteer using decent quality fluids is a waste of time.
My implements are swapped between 3-5 tractors and a skidsteer. On the farm about 6 tractors for the larger implements and about 8 for the smaller stuff and often the smaller stuff gets used on the larger tractors.

We run two skid steers, have two more in the loop. Few tractors too. Swap implements profusely with reckless abandon. We have grapple, bush hod, mulcher for each. Plus hydraulic post diggers. We have a 75 and 95 Kubota. 95 is a first year def and has been a Moe natcheral nightmarish costly experience. Costly because it has been in the shop so long and we still get the bill but we can't use it. It's 97 miles to the shop.

That's in like with what I'd LIKE to hear at least and makes sense to me, if the two fluids are compatible.

Would there be any concerns about cross contamination of hydraulic fluids by using grapples between a Kubota tractor (M4/M5) and a Kubota skid steer (SVL 75-2).

What about between same tractor and a JCB skid steer?

I’m active duty military in Germany currently so I can’t just go to a local dealer to ask the questions and I appreciate all of the knowledge shared on here!

Preparing for retirement and moving back to our family farm and researching new equipment. Planning to start a part time business along with our small farm.

I NEVER loan or borrow implements, and oil contamination is one of the reasons.

True, but in my case at least it's my own tractors and my own equipment.

I'd worry more about contaminated oil due to water or metal than oil from different manufacturers. One of the main reasons I don't rent impliments or rent out my gear. I wouldn't wory to much about swapping impliments between multiple machines if I knew they were well maintained.

I just installed remote hydraulic outlets and haven't had any prior experience with using them.

How do you keep dirt out of the connections?

Keep the caps on them.
