Why?
if you want to be a farmer go buy some farm land that is already cleared.
If it is not cleared already and it is in a farming area I suspect there is a reason.
Unless you have money to burn you're better off buying cleared and productive land.
Frankly, this is a multi-year project. I've seen it done and it takes a ton of work. Depending on the timber, one 12 to 15 ton or larger trackhoe with a stumping hook and thumb and a 30,000 lb or bigger dozer will take about a week per acre. Then you have stacks of stumps to burn and they don't burn. You have mountains of wood to burn and then pick up the charcoaled leavings because they won't burn either. The spread cost for just two pieces of equipment will be more than 3 grand a day and then there will be a lot of manual labor or a stick raker.
You asked for this. I usually don't comment but when I see a bad idea I speak up.
