Looks like a BH92 backhoe would be the Kubota model. Also check this Messicks video:
I could paraphrase the whole video by saying "fitting backhoes to a machine without one is harder than it looks. The subframes are all unique, the hydraulic plumbing is fiddly, and getting one second hand may mean it doesn't fit your machine."
If you're going to buy a brand new backhoe to put on the machine, that's very likely to work. If you're looking for a second hand backhoe, a) they're not that easy to find, and b) you have to make really certain that you get all the bits - if you have to go to a dealer to get a few bits you're missing you'll quickly get to a point where you would have been better off with a new one.
And with all that, you may end up where I did with my BX2350. I bought without a loader, then put a brand new loader on it. But a brand new loader on a second hand machine isn't worth any more than a second hand loader on a second hand machine. So you lose a lot of money quickly. That's not an issue if you're buying it to use it. But if you care about resale (i.e. getting your money back), be careful.
EDIT: The other option is a 3ph backhoe. There are reasons they're less good than a factory/OEM one, but they're also much more likely to connect successfully - they're made to go on a range of tractors. There's a Messicks video out there going through why and why not to get a 3ph one. I believe Woods are the go-to for 3ph backhoes.
EDIT 2:
https://www.kubotausa.com/docs/default-source/brochure-sheets/l60.pdf. Looks like BH77 for the ROPS models, BH92 for cab model. The BH92 goes out behind the cab, so actually in some ways more similar to a 3ph model (i.e. you're not trying to swing your seat around like you would on a ROPS model).
