MX5200 initial hyd fluid change, how important?

[hoffmtc]

Not in a huge hurry to buy something, but I'll need something come spring time for new/used tractor. I've been searching for a MX-series to pop up locally, and today a NICE looking MX5200 came up for sale. Has 126 hours on it. The person selling it is not the original owner, I guess someone got in trouble financially and this guy swooped in and bought it, and now reselling. I mention that because the seller does not know the history of maintenance.

I can see the engine oil filter has been changed, but the hydraulic filter is still the original factory. HST filter is factory as well.

The Kubuta manual says those MUST be completed at the initial 50 hour mark, and now it is 125 hours and still original. How big of a deal is that to you when buying used?
I suppose buying a tractor with several hundred hours on it you'd never know when the original was finally changed... but that bothers me.
If they neglected important initial maintenance, makes me pause about how they treat their equipment.

You sure about the change interval in the MX? I thought Kubota had extended the initial change interval by quite a bit when they went from UDT to synthetic fluid.

Just looked at the MX4800/5200/5800 manual online, initial change is 'MUST BE' completed at 50 hours.
The little dual-circle indication is the 'must be completed' designation.

I'd be more concerned about the air filter condition.

Change the oil filters out and send some oil to Blackstone Labs if you're concerned.

Thread title is "fluid"...manual only states that the filter "must" be changed. It doesn't say the fluid should be changed.

Line #17 in the manual states fluid change at 400 hours.

I changed my MX5800 filter at ~50hrs. No fluid needed, as stated above.

Filter definitely needed change due to break in debris but I doubt this would be a concern at 126hrs. Never hurts to call your local Kubota dealer (or stop in) and pick their brain. They might have sold the machine and have some record on it.

What I thought, fluid (hydraulic) change at 400. FILTER (S) change at 50. I knew Kubota changed the interval when they went to SUDT.

Well I've been confused on it, my new 5200 has 70 hours on it and now I think I know what needs to be done. I thought for a while that Kubota wanted a full hydraulic oil change at 50, and I wasn't going to do it, because that is ridiculous. I'm glad this thread made me look at it harder.

Sorry, yes my mistake, it should have read FILTER change, not fluid in the title.
It worries me that a simple maintenance aspect was disregarded on a new tractor.

How do you really know for sure? Ar the filters marked with the change hours or not? I mark mine in paint marker when I change mine but I only use Kubota filters so if I didn't no one would really know.

Original filters are painted the factory grey like the frame and engine components. Replaced filters have normal colors and print on them.
If you see an all-grey filter that matches the frame, it's still there from the factory.

Been so long since I bought mine new (2002 and 2005) I cannot remember but having said that, the new Kubota RTV my wife bought this last spring, the oil filter isn't painted grey, it's white with blue lettering. I need to change it pretty soon and the fluid too.
