I'm formerly from TN.
Knowing your hills in that area, an RK55 would be the ideal ticket, balancing power and frame for your needs.
There are several RK stores in your area too.
RK tractors are TYM/Kukje and Yanmar engines. A 60 year history together.

Yanmar has made Deere compacts and larger engines for the past 48+ years.
The engines are found in Komatsu, CAT, and other earth moving equipment.
The engines are also in Marine for sail boats to tuggers to ocean cruise ships.
Yanmar engines are global, found in many brands and have wide parts support for decades to come.
When looking for a machine, you need to know about future parts support in the long run.
We've raised several hog breeds. Some are mean and will not hesitate to eat a human. After 5 different breeds, we settled on the Duroc.

If you plan on raising other livestock and prefer NOT to have you pastures turn into mud pits, then the grass grassing Red Wattle Hogs are the best. And their meat is closer to beef too.
Red Wattle hogs are known for their hardiness, foraging activity, and rapid growth rate – they may be fully mature at the age of three.
