Hey LT, I overanalized the situation like you (although I don't think it was overanalized, I just called it good decision making). I have finally come to a conclusion I don't think you will like, it's that you can't get it all in 1 package. I myself am clearing land and building a house, and wanted a tractor also to maintain land after. Anything big enough to do any real damage would suck to mow the lawn with, and anything small enough to maintain and not destroy the grass, or be too big for manuverability would suffer when doing bigger jobs. I looked at the size tractors you are looking at, and for that price range, I was able to purchase an older JD 410 LBH for the major work, and a smaller Kubota for the maintainence. So that's what I did.

My conclusion? Well after learning a lot about machinery, developing land with a tractor really is not my first choice. Yes, a loader/backhoe is useful for many situations, but after the time it takes to pull out trees (even with a BH arm that weighs 7500# alone and has a 19' reach), then trying to change the lay of the land with the loader, If I could do it all over again, I would have purchased a mid-sized tractor with a loader, and a mid-sized bulldozer hands down. To watch the dozer go where only my tractor would dream of, and push over a tree, roots and all in 2 minutes what would have taken me a couple of hours with a chainsaw and loader, and to actually change the lay of the land effortlessly it was no question, If I would do it again I would get the dozer instead of the LBH, and sell it when the job was done.
In my opinion the dozer is the right tool for the job, and don't get me wrong, the LBH is great, but it is made for DIFFERENT tasks which it does well, like picking up dirt and moving it (not smoothing it), and digging deep holes, but not really taking out hills. Yes, you can get a standard tractor with millions of attachments, but in the time it would take you to hook all those up and pay for them new, I would have the work already finished on a dozer for 1/2 the cost, and with the tractor, then you still would be stuck with the same size question.
So if a dozer isn't in your futrue (feel free to pay someone experienced because knowing soil is a whole different ball game!) that's fine, but if you take 1 thing from me, it's that 1 machine will not do it all!
