I'm completely new to the tractor gardening arena. I'm getting a moldboard plow and have a set of cultivators (image below). I'm looking at disc harrows, wondering if they're needed too, but I've never worked the soil with a garden tractor before. I'll be working virgin land too, if that make a difference.

I've tried looking online and cannot seem to find a Tractor Gardening for Idiots guide anywhere. I want to know what implements to use when and for what outcome. The plow is easy, a tiller is easy.. it's the cultivators, discs, and all other items that I'm not so sure on.

I need to plant my crops in raised rows (to prevent erosion or flooding) and want everything from tomatoes to potatoes to melons.
