If you have a atv or 16hp.garden tractor,a company called Worksaver makes a 52in.disc.
I have one and they work great.I put 3 food plots in last Sept.,all about 1/4 acre each.
I see them in the Cabela`s and Northern Tool
cataloges.I`m new to this site,and have been
reading along for about 1 month.Keep up the
work.P.S. I think the tiller would be a workout!
