Probably so, as the Kubota BX market is much larger. BUT, the thing to ask is if the SSQA option is available soon, you need to ask is the SSQA adaptor going to be just a matter of unpinning your original bucket and pinning on the adaptor and getting a new SSQA bucket or converting your old bucket to SSQA. The bad news is that this is liable to be more money than it would have been to get SSQA to start with. Why in "heck" do you have to wait until August to get the tractor set up the way it should be from the get go. But I suppose it is what it is at this point. The point is you don't want "pin on" front implements to begin with in ANY brand. They are just an "embuggerance" (you can ask our Aussie friends what that word means if you did not clue in to it immediately.)
Anyone that says they enjoy using "pin on" attachments is less than forthcoming. SSQA is the way to go. It is a standard across all brands, and it is a good system and will make your life much easier and will open up a world of front attachments for you to consider for your needs.
