3-Point Hitch What size disk for a l4200

[fastback88]

What size 3pt or pull type disc can my kubota l4200gstc 4x4 with fel and ag tires pull. I will be using this along with a 6'S tine 3pt drag and 6' boxscraper to maintain a motocross track.
I have a 5' cheep kingkutter disc, (which I have not tryed yet came with the tractor when I bought it this winter and the frost is just getting out of here) but I don't think it will hold up using it on the track and it is not wide enough I need it wider than the rear tires atlest.The ground in mostly black dirt with a small area of clay mix. Which would be better 3pt or pull type I have rear hyd ,so I'm guessing the pull type with wheels would be my best choice but how wide?
Thanks

Many choose three point when buying new do to the reduced cost! I would think that anything 8' or less would be good.

You say this disc will not be used for agricultural purposes but rather for track maintenance.

So, consider a pull type disc of maybe 10 feet or less.
