Is this possible, or is it me?

My B7800 was due for the 300 hour transmission fluid change. When the dealer did the 50 hour, he put in Ambra 134 and the tractor has worked flawlessly since. I decided to go back to Kubota UDT fluid.

I did change both filters with Kubota original and cleaned the screen.

Now this is the strange part, the tractor has lost ground speed. At PTO RPM, the tractor is noticably slower on ground speed. Other hydraulics seem to be the same.

What happened?

re check your fluid levels. a good chance air got into the system, as you drained / replaced it and filters.

if you just got done using the machine. let it set for a couple hours so air floats up and out of the oil, and then check the fluid levels. if ya need to add more oil then most likely was the issue. re check the fluid levels a couple more times after that (after each use and letting it set before checking)

it is also winter... so it takes some time for oil to warm up. cold oil = honey that barely flows, warm oil = flows like water. make sure ya letting things warm up, before putting a heavy load on things.

double check the oil right after running it for some time, and see what the oil looks like. milky? foamy? little air bubbles in it?

I changed it yesterday and used it several times since then. Oil level is normal and clear. I was land planing my road as we had a MAJOR storm, .3" LOL. I worked it hard with full pedal at PTO speed so it should have cleared any air out.

It may be winter in IL, but this is the desert. Temps today were 60ish.

Do they still have the chili cook-off in Rosamond?

Sorry, don't know about the cook off.

Is the ambra 134 fluid a synthetic?

No, it's New Hollands standard fluid... and it costs a lot less than what Kubota UDT does!

"it's New Hollands standard fluid"
Have you consider going back to what was being used?

Yeah, but I hate to dump $90 worth of new fluid. I just guess it will go a little slower, just like me.

I should mention that when the Kubota dealer did the 50 hour I asked them why they used the Ambra and they said they thought it was a better fluid. Since this was my first tractor who was I to question.
