Wow, thank you all for the input/education. It is hard having to trust the knowledge of dealers, when you don't have a clue how long they have been doing it, or their background. I do not consider myself a newbie, but certainly have limited brand/model exposure, so when they make these comments I immediately think I'm missing something. Obviously, one of the many values of this forum is the massive knowledge base in order to learn and fill in the gaps.
The second dealer after contacting Kubota sent the following on the two items. The three point arms seem pretty reasonable.
L7334 Base kit/1st lever/rear remote valve installed $975.00
L8430 Telescopic lower links[3pt arms] $205.00
As a total aside as to price for the rear remote option, the Kioti CK2610HST dealer quoted me $408 for two rear remotes, one with detent. No labor to install, but I think he is working it into the numbers somewhere else.
TheMadOne: I know that one can get carried away with the options, but what I did not say in the original question is that my goal is to get any option that may help when I am in my seventies. The ONLY reason I am buying a new tractor is simply ergonomics- I hate getting in and out of my Ford 1700 with size 14 boots, see attached. I usually buy something and figure I will go aftermarket for this and that, but for once said forget that. I am ordering any option that I think will have any value later on. I think I'll even take the hit and trade in my tractor, instead of selling it myself.
I currently have Pat's Easy Hitch or whatever it is called. I looked at my implements, and a few will not accept the Quick Attach due to the top link configuration, so will see how this goes. I saw there are adapters for them too. I have always been terrible making these connections, so another reason for the adjustable three point lift arms, and at a minimum hydraulic top link. I will rethink this a bit per your comment.
S219: thanks for the explanation of the backhoe connections, which explains the lack of rear remotes.
Thanks again everyone for the education, Toukow
