The 3pt on my YM2000 has died. The FEL still operates normally. I have adjusted the 3pt speed control in and out multiple times to no avail. I intend to drain the fluid and pull the internal filter tonight and try and locate the main filter and pull it as well. Any other ideas or suggestions?

Was the 3pt working normally just prior to the failure? If so I doubt the cause is the filter.
If by the speed control you mean the large knob just in front of the seat, I believe you'll find that only affects the drop rate for the 3pt arms and not the rise rate.

That large knob in front of the seat should always be fully open. Always unless you are trying to lock something in the up position with the engine off. To affect the downward drop speed, there is a small lever (usually with red plastic on it) that is for controlling your drop speed. Also their is only the internal filter. there is no external main filter. Not on my ym2000 anyway.

Since the OP is talking about a YMXX00 model, I'll not question phatgemi's cautionary statement about always leaving the service lock valve full open while operating the tractor. However, for other models, check the last several posts in the "3pt problem" thread. It appears there was a design change somewhere in the Yanmar production cycle and on, at least some of, the YMXX02, YMXX20, and FXXXX models, there is no "drop speed" control. There most definitely is NOT one on my YM2220. On those tractors, it appears (assumption, not yet proven) that the way to control drop speed is by throttling the service lock valve.

Whatever you say, Tom, these are gray market tractors, and no one knows for sure.

Sorry, Norm, I guess I'm missing the point of your post.
True, these are grey market tractors, but Yanmar didn't build them as such. They were built for a specific commerical market, and I assume that Yanmar, being a competent design and manufacturing organization, intended to support those tractors in that market and would have used normal configuration control procedures during their production runs.
It's also true that they have been away from the factory for many years; plenty of time for parts from different production to become intermingled and for individual tractors to be modified from their original configurations. But that only reinforces my statement that some Yanmar tractors do not have a drop rate control. I really don't believe that's open to question.
My point was that there are a large number of posts in this forum declaring that the rate control lever must be used to control implement drop speed and that the service control valve must be fully open while the tractor is being operated. Many of those posts include warning of dire consequences to the hydraulic pump otherwise.
Many of those warnings are not obviously directed at a specific Yanmar model. They may not be universally applicable to all Yanmar tractors. Therefore, they can be confusing, even alarming, to neophytes such as myself who own one of those tractors not equipped with a rate control lever.
The implement drop rate should be controlled to prevent free fall when the 3pt postion lever is abruptly moved to the full down or "float" position. Without a "rate control lever", the "service lock valve" is the only candidate, known to me, for that function. If you know an alternative, please, make it known.
There is at least one tractor make/model whose operator manual specifically states that the lock valve is used to control implement drop speed. I have seen copies of that manual, but not the tractor. My neighbor owns another such tractor. I haven't seen his operator manual, but the tractor was built by Yanmar, is green and yellow, and uses the lock valve for drop rate control.

Just that, being gray market, there are no factory produced operator manuals in English, explaining the correct operation, and no-one seems to know for sure. Maybe if we could hear from someone with a US version tractor with no "drop speed control lever" who has an operator's manual.

Yes, having an operator's manual is no guarantee on these tractors. Things got lost in translation from Japanese to English. My manual has many parts just plain labeled wrong. It says the transfer case lever for 2wd to 4wd is the differential lock. There are several such oddities in my manual. Luckily being a simple tractor I already knew what everything was before the dealer I bought from mailed it to me. Had I never operated tractors before I might have believed everything in my manual and really made a mess of things. Mostly I wanted the manual for the capacities of all the fluids and it was correct about all of those. As for everything else, well...
