Torch
I have a MF TO30 and a 4row disk that works great in small areas.
I'd like to get my hands on my dads Farmall, but he'll be dead before he gives it up...and he might not then. My place ain't really big enough for a tractor and I don't know if I'd have enough room to use it in my "garden", but if my adverse possession works out, then I'll have a bigger spot to work.
