No, sorry, that's not correct.
The Euro style couplers named "Euronorm" or short, "EURO2", are absolute universal.
This standard is neither loderarm specific nor brand specific and it fits tractors from about 30 HP up to over 250 HP.
Every implement/attachment like buckets, forks, graple, which is manufactured within this standard fits to every Frontloader with a "Euronorm" coupler.
The "Euronorm" is the most popular System for frontloaders in europe and in many other parts of the world. - You can get it, if you want, for every Kubota-Frontloader (except the very small ones I guess).
@ 3bfarm: which is the critical point that doesn't fit? The lock bolts?
Here in the states Kubota loaders don't follow the Euro attachment standards, you can't even get one factory equipped with it.
I know it's completely different in and around Europe, like Germany where you are.
The available units here are different between loader US models, that try and follow John Deere Euro hitches here which seam to be far from standardized, especially older models of the hitch.
I'll bet you don't use SSQA (Skid Steer Quick Attach) over there, that is the standard universal for attachments here.
One thing I wish is that we would have converted over to, is the euro three point quick hitch (triangle design), it's a much easier to hook up to, and better design than the current US standard quick hitch.
The euro design can also incorporate PTO hook up operations where there is no such hook up options on the US models.
