I use a chisel plow and disc chisel, so I haven"t plowed for years, but for your 60 acres, with sod, I"d buy a 4-18 moldboard plow (auto reset if you have rocks), cut the plowed sod with a disc, and then hit it with a field cultivator with a tine harrow behind. I"m not a fan of discs that all the newbies think they need...since they pack the soil, along with ridging it...vs a FC which digs it loose. If I couldn"t afford the disc, a couple passes with the FC would be fine, and give a better seedbed.
I run a 12 shank White disc chisel behind a JD 4450 MFWD, rated 145 hp, cranks 190. I run the 12 shank Glencoe chisel in bean ground with a JD 4240, rated 110, cranks 125 hp. Clay soil, similar to what paul farms, about 90 miles North.
