Tim.....
please tell me you hit the ZERO one too many times???? 200 hours?
IF truly 2000 hours - I would change both and mark it in the book and look forward to doing it again in the next 300-400 hours.
Remember something about "oils" in general .......... much like sandpaper - it is great once it is out of the bottle, but after a while it looses its zip. Oils break down over time of use and will no longer do the job it needs to do.
Just cause it works well does not mean it will continue to work well in the future.

Adding to what 85Hokie said, there is condensation and contaminants to consider. You definitely need to change the oil and filter. If it has a powered front axle, change that fluid also. If it has not been done, change the engine oil and filter, air and fuel filters, also flush the cooling system.
Maintenance is always less expensive than repairs, however, some people like to gamble and put off maintenance. In the end, the house always wins, because the odds are in their favor. Have you priced the cost of an engine recently?
Thanks to everyone for the replies. I guess you all think I should take the risk and change the oil. I probably will do that this summer. Not to question your knowledge, but just for fun, consider this. 2000 hrs on a vehicle would be around 100000-120000 miles. I have driven several cars and trucks, manual and automatic, well beyond this without a problem and without changeing trans fluid. I think the 300 hr recommdation in the manual may be, in part, an oil selling gimmick. Thanks to everyone for the help.Tim.....

You may be right but the only way to tell is to send in an sample for analysis. I recommend blackstone labs you may want to contact them to see what tests should be done. I would love to see how the the 2000 hr oil trans/ hydraulic oil comes back.
You went 120000 miles without changing tranny fluid? If you think 2000H is equivalent to 120000 miles, how many speeding tickets and traffic violations do you get every year? Better examine that math. 120000 miles in 2000 hours averages to 60 mph every time you stick the key in the ignition, if you NEVER stop for fuel or NEVER turn the ignition off. Like Jethro Bodine, I'm purty good at my cipherin and gozintas. It's difficult to average 60 mph on a 1000 mile trip, let alone 120000.
I change mine but there is a true story of a Mercedes that went a million miles with no manual trans oil change. Food for thought.

I wonder how much and how often any oil was added to the transmission during that million miles.
There is a transmission repair shop every block or so around here, so a lot of people must be changing their transmission oil and destroying their transmission.
The bigger M series have a filter change every 500 hours, fluid is reused then replaced at the 1000h mark. For a guy who’s busy, that could be once a year, or shorter. With a capacity of 15+ gallons, it ain’t something you do for fun unless you need peace of mind spending $500+ on oil. So for 2000h, on a real busy machine, that could still be within a year or two. I don’t think it’s totally unreasonable. I bet there a ton of older tractors out there that the (sorry not insulting) cheap (frugal) farmer has not ever bothered to change due to the cost or hassle. However, if it’s never been done at all since new, those filters/magnets are likely getting full of crud. The filter may bypass if it becomes clogged.
On the topic of long oil intervals on transmissions, VW has a ‘lifetime’ oil in some auto’s (a differential section within the transmission) and the manual transmission has no recommended interval......

Blackstone has a good reputation...but sending them a sample from a 1985-90’s tractor that has 2000 hours on it without an oil change and without previous sampling-data will be a waste of time and money. Spectroanalysis is only useful if regular samples are submitted in standardized samplings.... or in rare cases, in autopsies. If the tractor is operating normally with 40-year-old oil in the tranny..... then it’s done well and likely needs changing. Doh.
Don’t be surprised if after changing the fluid that you find your tractor develops leaks and perhaps even misbehaves somewhat. The “rule” followed by ”old mechanics” is either change it often-and-regularly.... or never at all. The fresh oil may clean up and dissolve varnish and contaminates which have developed over the years and the new oil will then find a way to soften and bypass seals and glands that have been working just fine...but may leak and fail with fresh oil.
As an “old mechanic”.... BTDT.
Briggs & Stratton small engines now are factory filled, and never require that the oil be changed. Just check and add as needed...

You value your time – and any timesaver that makes life easier. That’s why we developed the first walk-behind mower engines that never need an oil change. With our new EXi Series – Just Check & Add™, never change the oil – ever.
Yes, I have always wondered if "oil change" was a unneeded $ maker. Just like modern cars hardly need maintence or tune-up, so the dealers invented new car operations like engine flush....What about Marvel Mystery oil, sounds like Dr, Marvel aka The Wizard of Oz.Briggs & Stratton small engines now are factory filled, and never require that the oil be changed. Just check and add as needed...

All I will say is 2000 is impressive. Bet that filter media let go 1000 hours ago, and is bypassing... That thing is obviously a tank since it still runs. Original owner? Stored outside/inside?
Please for the sake of all of us cut open that filter so we can see it. It better be grey too!

Briggs will be quite happy (I am sure) to sell you another engine when that one wears out. They know the average owner does not give their small engines proper care.
(Unleaded fuel and synthetic oils (if properly filtered) has contributed to long engine lives....and most owners don’t keep equipment for decades, ...instead trading it in or tossing it long before its time would be expired if it were properly maintained. )
I would not suggest extending or abandoning oil changes if you plan to keep equipment to hand-down to grandkids and great-grandkids as I do.

Kubota is ridiculous on hydraulic oil changes !! Hydraulic oil should easily out last motor oil that’s in combustion chamber.Hydraulic fluid is very high detergent oil in a closed system.There has been Hydraulic fluids in heavy equipment like JD excavators that is rated for 4K hrs change intervals 1k on filters.Took me 2 yrs to hit 400 hrs but Landscaper or full time farmer it could be 3-4 changes a year ridiculous in this day in age.
