Seed drill - drilling for time

Bill has a lead on a seed drill that would work on our tractor. Its a 2 - 14 (or 8 or something like that). I don't know anything about seed drills. It's a manual one that will work on our old tractor. Supposedly this drill can even be pulled behind a 4wd ATV. This could be a nice find as we try to improve our beds and the overall pastures. I spoke to an organic consultant at MOSES organic and she recommended that we cultivate and seed drill our garden/fields with cover crops and then turn it in. At this point, I mostly want to get rid of the massive amounts of thistle we have. Oh, and the buck thorn. Goodness, do I hate buck thorn! I think I'm going to be fighting that fight for a long while. We've actually decided to let the it be for now until we live there full-time. It really needs constant, vigilant attention to be eradicated. We seem to be doing more harm than good with our occasional attempts. So much to do and so little time.
