stone cold u can pick up sections of diamond tooth harrows pretty cheap. Not too many farmers use them anymore so you might be able to get a few sets off an old farmer. Get yourself 4-5 sections and lay them out horizontally, then chain them to a horizontal bar of some type. Then hitch up the bar to your quad, tractor etc. But you should be able to find an old set of diamond tooth harrows pretty cheap out there someplace.
