Some good ideas so far, if you can hire someone else to do it and don't need a tractor for other stuff that will be the cheapest. There are alot of good used tractors in the 40-50 HP range that will work also. I have a J.D. 4700 diesel I use (48hp), it will pull a 2 bottom plow. I also have a 6' disk and a 10' wheel disk I use with it, along with a 4 row planter.
