Can anyone tell me why I'm seeing two filters on my HST. The one on the right is clearly for fluid coming from the hydro pump on the engine. The one on the left screws directly into the tranny. Am I required to change both at required intervals? 50, 200 hrs etc... Many thanks in advance!

Yes, change both filters. One filter is for they hydraulic fluid which runs loader, PTO, etc. The additional filter provides finer filtering for the HST transmission. They are not interchangeable and I believe they are different physical sizes which should prevent any confusion.
Just did my 50 hr on the B2601. oil filter and change oil, hst filter and trans filter. Only lost a small amount of fluid on those. Stay with what is recommended and you can't go wrong.
On my B2650's first service interval (50 hrs. filter change only) I decided to first drop the oil into a brand new clean 5 gallon pail. Thinking it would avoid a mess due to any unknowns, my screw ups, etc. rather than counting on a very quick filter change without dropping the oil. It would give me all the time in the world for the first change to see how things came apart and fit going back together and I would just pour it back in afterwards. Plus, I could look for any metal shavings, etc. in the bottom of the pail.
After draining the oil I decided not to reuse it. It was discolored, had a little scum in it, along with maybe some fine machining odds and ends. It just didn't seem right to put it back in so off to the dealer for a new bucket of SUDT2. The next scheduled fluid change resulted in nice clean hydraulic oil removed from the transmission.
If this is your first 50 hour service.....a clean bucket is cheap insurance against any little mishaps that might lead to a mess of hydraulic fluid on your floor.
