Having read posts in this thread each day, I thought a few constructive comments were needed.
I would treat a 3PL mount backhoe very gently. Take a few minutes to understand the forces, shock loads and stresses which are not just applied, but in a lot of instances multiplied, to points which IMHO are not designed to take such forces. Are you sure your tractor's rear casings, 3PL mounting points and overall strength up to the task?
MadMac & tkevan - different manufacturers use different ways to provide multiple-category compatibility, be it reversible arms with bushes to insert if required, or double holes in ball-ends with shouldered attachment pins if required - whatever is applicable is a real convenience in later-model machines.
That said ..... keep in mind the possibility of attaching an implement which is unsuitable for the tractor - think safety, also warranty issues as previously mentioned.
5030 - we all should realise our machines are generally sized to fit our widely-varied requirements, budgets, tastes & preferences, plus a lot of other factors. Additionally, we aren't all farmers, earthmoving/hay-making/slashing/clearing/other contractors or mere enthusiasts either. Some of us are retired, having had decades of productive time "in the saddle" or maintaining and repairing machinery for owners, whilst others are still working in these capacities, and obviously enjoying it (in overall terms). I can't recall just what type of operation you have, but I'm sure you wouldn't mind enlightening me!
Therefore, we should, and generally do, show appropriate respect toward each other and keep in mind the whole idea of this and similar website(s) is to assist each other, swap information and ideas, provide technical and practical help if possible. At least, that's what I try to do.
BTW, your tractors are almost the same size as my sister's three - 2 Cases & a Fendt. She has her own dairy farm here in Aust - a milking herd of 300-320 Holstein-Friesians and four staff on board. I visit for a few days as often as I can to help with some maintenance here and there - love it there!
Here are a few typical pics:
I also checked a few pics of your model Kubotas - they're kinda "cute" too!
Maybe this is comparable to your next tractor?

Mate, with utmost respect, we all understand it's "horses for courses" but people have vastly different tasks they need their machines to do.
At the end of the day, let's all be gentlemen (and ladies) and understanding toward each other. Life needs to be easier, not more difficult.
May each and every day be safe, productive, enjoyable and rewarding for you, and everyone else who reads this!
Spare a thought for all the unfortunate folk currently battling huge floods in Texas - my thoughts and prayers are certainly with them!
Having experienced a few floods in my time, it's certainly no fun.
