OK, I confess. Yes, I do have a tractor.
You can take a boy out of the farm, but you can't take the farmer out of the boy.
I use the tractor for tilling, mowing, and moving snow. I really don't know what to suggest for a tractor for you. This one is 55 HP. It is probably overkill for my 1.5 acre lot. However, when it comes to doing anything it is great to have the power. I do a bit of custom tilling. This is an older tractor with a new paint job.
Tractors are expensive, and perhaps you can find a used one? I don't know what to suggest if you are going for a new one. I would see if there are any farm implement stores around and go talk to them.
