Wow, lots of good info to wake up to, thanks to all.
Definitely rethinking the HST, but the DK on the lot does not have it...so that kinda stinks (nether did the nx5010 though). If I go that route no making a deal oh this tier 3 (interim 4?) I guess.
The backhoe is sticking in my mind. A sample of the projects I have is at least 200 feet of trenching for various projects, excavation for a greenhouse base, small koi pond (hand dug one before, but NOT in this soil) many stumps will require some attention, and the list goes on. I may only pull it out a few times a year, but like the 4wd on my truck it is there when I need it and I don't have to ask for someone to do it for me or rent equipment. Probably just justifying to myself but going to try to find a way to budget this..hope I can do so. I really couldn't find much saying it should be stored in a climate controlled situation for humidity etc. I couldn't afford such a set up, and I would hope a piece of hardy equipment such as this wouldn't require it. I know that most true working backhoe attachments spend much of there time on the tractor anyway, so usually outdoors. Mine would be stored in the enclosed pole barn when not in use.
As far as tires, I won't be doing a lot of fieldwork. Few food plots at most (our gardening is all raised beds). Much time will spent on the dirt roads, trails/roads on the property (some of which I will clear), in the woods, dragging trees for firewood, work around the house site, and clearing small sections at the time. We plan to leave the vast majority of the land forested for our own enjoyment and to cultivate the wildlife habitat. I actually did mention the rolling terrain we have, so loaded tires may be of some help I'm thinking. Leaning strongly to Ag tires at this point. Not worried about tearing up a lawn and will rarely be on pavement.
While my wife is no mechanical expert she tends to have good insight. Keeps asking me if we are not better off getting slightly larger and heavier for not only power but stability/safety. Now while I realize we can turn any piece of equipment over given the right circumstances, I like her argument cause it means I can go with something a little larger with less guilt

.
Sooooo, while I was thinking I was just walking in and getting something of the lot I am going to re-examine my process. My thoughts at this time are to have the dealers price out a 50HP or close as I can get (hopefully staying with Kioti in part because ergonomically it fit me so much better than others) keeping in mind my total weight, hydraulic gpm and PTO hp, hydraulic extras discussed here, and likely HST (if 1k difference or so will do). Will price with and without backhoe but really want it. Will also need at least a medium duty rotary cutter and land planer but wonder if I'm not better off going to the auction for these (Woods, Land pride or BushHog are on the wish list). I think I will try to go with Ag tires as I dont see a down side. If they are willing to load them for a 100 bucks sounds like a deal to me.
While I was excited about the DK will just have to make a final decision on HST vs shuttle and go from there. Will then look at what I'm offered and how incentives play into it and "zero percent" vs free FEL etc. Will then get comparable price on Mahindra and Kubota, but the dealer support is not as close and I know less about those dealers. Use as a bargaining tool but try not to alienate a dealer I think I want to work with. Whew! Not going to be quite as simple as I thought LOL. Hoping to make this purchase in the next few weeks at most so I will continue looking for ya'lls input on here...keep it coming!
