Tractor Hydraulic Fluid Data Page

I was digging around on the web for data on what the heck "Super UDT" properties are in comparision to either UDT or Amsoil or any other fluid. I didn't find that but I found this. It may be of some interest. It lists the properties of a few of the more popular THF's.

In case your interested I just found a tractor Hydraulic oil who's speccs actually say it is to be used in place of Super UDT. It is Chevron Synthetic All Weather THF. This is the only oil to my knowledge to say Super UDT on the label.

Greg and John,

Thanks! I am at 47.5 hours and counting till the first 50 hour change out. I really do want a "better" fluid for winter use, but not at the cost of summer use! The Chevron product sounds like the hot ticket.

John,

Does your owners manual say to "change" the hydraulic fluid @ 50 hrs or just the hydraulic filter?

I'll double check the JD manual, but I thought it said change hy. fluid either 300 or 500 hrs. & the hy. filter @ 50 hrs.

Maybe the "HST" units are different?

And yes, I agree, I'd wait til late Fall for the full treatment of synthetic hydraulic fluid... for the most benefit of your $$$.

Hi John,

{I stand to be corrected...}
This is from my JD owners manual on my JD5205:

First 100 hours: Replace transmission-hydraulic filter {Not Oil}

Every 250 hours:Replace transmission-hydraulic filter

Every 1200 hours:Change transmission-hydraulic oil and filter

[john_bud]

John,

Kubota service manual states that at 50 hours to change;

Engine Oil
Engine oil filter
Hydraulic oil filter
Transmission Fluid
Front Axle case oil


There's a bunch of Checks and Tightens too.

Thanks for making me check! It's always fun to look into the service manual.
(No, I DON'T get out much, why do you ask?)

Hi John,

I guess I'm surprised at changing the fluid so early... on the other hand, I don't have a hydrostatic tranny either. So I imagine this is typical of HST's?

Just wondering...[img]/w3tcompact/icons/smile.gif[/img]

[john_bud]

John,

I dunno, I would think that there is a lot of shear forces acting on the fluid in an HST and at least 3HP of pure heat added to the mix. (power loss greater than a gear tranny) With all that going on, I think its a good idea to change the fluid often!

As they say, your milage may vary...
