Tractor Sizing What size disc harrow?

[beefkiller]

I have a Yanmar FX22D FWD with a FEL and its rated at 26 engine HP and 22 PTO HP. Its 4' wide and weights appx 2500 #. What size disc harrow should i get 4' or 5' and what would be the max weight of disc harrow? I want to get the biggest set but dont want to overload the 3 point hitch. Thanks for any input.
