we are on 36 row spacing and 12 row equipment which amounts to 36 feet. We set track spacing and implement width at 36 feet. We are on RTK though. Just have to make sure the TCM is calibrated exactly right though!!

Oops, forgot to add that we don't have any offsets on the equipment but do have 1 tractor that always has to have a 0.5 to 1" offset to make the rows come out.
