A tractor with a loader, such as the model you describe, can be very effective, if used carefully, you have to watch the stack, lights and hoses. Reason I say this is, I've done a lot of clearing with my old 850 ford with a wagner loader. Mostly pushing things off to the side after cutting with a saw or what have you.
Safety is a big concern, all kinds of things break, snap off, spring loaded limbs, vines, this work can be extremely dangerous.
Dozer is ok, but larger trees, stump holes, rootballs with lots of your good top soil attached can be an easy way to make a mess and erode or lose top soils. Dozer gets much better traction, can push trees over easier, but the tractor/loader would be a much more useful machine to have long term.
I'd look into rental or hired out, unless you really have a need for a dozer, the model you suggest is light and not all that powerful, decent grading tractor, and similar, for clearing I'd want something bigger, a little more power, and with a brush cage, limb risers and similar.
Compare hired out, and rental, then ownership.
Fence rows, a dozer wins hands down, don't care what size as broken fence posts, like old t- posts, all kinds of hardware and junk that can flatten tires is very possible, I'd not run a tractor in there unless you carefully push from the outsides and work into a windrow, piles and not cross the path of the fence line. I could not believe the junk that came up in a small fence row that was cleared by the power company, allowing me to expand a field, my friend came over and plowed that section after I had been working it, and some tire poppers appeared, post anchor, sheared off t-post, glad that JD 7420 did not hit anything, now its clean but not only is it good to clean off he surface, I'd want a hoe to dig down and explore the soil, to insure nothing was in there, that and or a metal detector.
