Good luck! I have seven acres that me and my dad planted 2200 trees on about nine years ago. Alot of work does not describe it. We bought all the trees from the Ohio DNR for around a quarter a piece if I remember right. They all came bare root and we had to wedge them in. It was a bigax blade looking thing and you jammed it in the ground and shifted it back and fourth a few times and the stuck in the roots and mashed the dirt shut on either side. We were about dead after four days of hard work! But any ways, back to what your after. We planted two rows of pines around it followed by two rows of ash. Then the whole north half we planted red and white oaks. They were put on ten by ten grid with the rows staggered. You will need to mow the first three years at least to keep the weeds from choking the trees out. But we wished we would have went with a twelve pattern. Two acres and you should be able to do it with just a lawn tractor. But we have a real small tractor with a five foot bush hog and it is real hard to make the corners, I have taken almost all of my trees out on the ends of the rows by hitting them. If we would have went with 12 by 12 I would have been OK. Make sure you mark you rows so you can find the trees if you do not get into to mow as much as you should. Good luck and it will be rewarding. All of mine were sticks a foot high, and now I have some oaks that I can barely get both my hands around the trunk. I would also say that I did good since I had about 75% of my trees are still alive, expect some die off.
