The First Choice units, certainly the 20 Series ( "standard" series ) are much different from Deere's light units. We are hearing a lot of good comments about Deere's heavier units, the "MX" series though.
But please let us know the Deere "Junk" model you have and what is wrong with it. We always want to learn, especially from someone with an email address "bush hog".
Thanks for your interest and your great advise on the slow pull-ups of some websites. Jim and I were discussing that very point earlier this week. You guys want facts, not fluff and you want it fast. We will try hard to stick to those 2 principles.
Keep pushing us and we wil get it right.
I have the 48" KK brush cutter on my TC21D. Works great and the tractor handels it just fine. Ide do the 5' on my tractor, but i like the 48 so to get inbetween trees. Power wize the tractors got it no problem.

I have a 48 inch KK on my B2410. That would also be the most useful size for your B7500. See the threads on modifications to rotary cutters. You will have to drop the pins to the lower bolt holes to make the KK work.
Those First Choice look nice. J
I think the main problem there is that a 2 inch tree will stop your tractor cold, that is, the tractor is the limiting factor. I doubt you cut any 2 inch trees with a 7500 or such and if you attempt to do so it will soon destroy the tractor--I could be wrong. J
1" Trees are no problem. Ive done 2" plus, but i push them over with the loader then slowly back the hog over them at a high setting then lower on to them. Turns them into spliters if ya do it right. Take the big ones slow. It will spliter the stump down to about 2" high and rot off by the following year as ya mow. I rarely staul my tractor bush hoggin. here is a pic of a path i bush hogged into my woods.
