We're putting in garden space in what has been lawn. I wanted a tractor-pulled tiller, but geez, they're pricey. Now I'm thinking one- or two-bottom plow and a disc. We have an older 20hp compact diesel tractor. I think it will pull a plow, but I'm not positive. Any other suggestions or thoughts? Oh, we're considering pigs for future tilling needs, but need something done sooner.
