I have the Ford/Dearborn 3pt 8ft tandem disk. It only weighs 750#, so it can handle the lightweight duty. I would not bother trying to make it heavy duty as it does not weigh enough to take advantage of that. The only thing I did to mine was to cut off the angle iron from the 3pt to the disk and replace it with chains to give me more flexibility since I have the hyd top link. I have had it 6 1/2 years.
