Why not make one? We just got through making one and have a couple hundred dollars in it but it was closer to a grand for anything I could find to buy. It is a 15" drain tile filled with concrete and wire, then capped. only thing I will upgrade on it is fingers to clean out the roller and possibly make a frame with a 2" hitch on it for better towing. Weighs ~450 lbs.
Have you tried the guy in Savannah? Edwards Implement 731-607-2650. That's where our tractor cultipacker came from. Will be working food plots as well Saturday in Bolivar. Good luck.
