Ok, I'll chime in on the small tractor recomendation.
If its primarilly going to be a hunting property tractor, you'll want to take into consideration that you will have maintenance and bushhogging to be done. I like the compact tractors for this because they can cut 4wheeler trails very easily, usually between larger trees that you wouldnt want to remove. I use a 4' cutter because it wond hang on a tree while cutting.
I bought a Yanmar 2000 tractor package with a new 4' cutter, box blade, and trailer. Then had him throw in a used tiller,4' too. I'll say this goes down as one of my best investments..... /forums/images/graemlins/grin.gif
The tiller is worth its weight in gold, much more valuable to me than the $500 I payed for it. However, it may not be the best soloution for your rocky situation. I would recommend the chissel plow. I have used one in the past to do food plots and it worked well. The crop will come up with rocks left behind. You can remove them as time goes by or as a weekend project. But either way, your goal is only to soften the ground for fertilizer and allow roots to establish. You surely wont go wrong with a 30HP JD or NH, I just went the inexpencive route with a 24HP 4x2 and its working really well for me. at about 1/4 the cost.
Happy shopping......
