We lower our tailboard, can't remember how much, but we moved shoe as far back as it goes and add acouple of inches and set it there. we did remove a bit of rubber from straw spreader. we use our own homemade ones and run 3 to right and 2 to left. we run 30 plus feet most days depending on wind etc, very even spread. We also had a set on an N6, don't recall the dimentions but there were some differences as we reused them on the 2 series R machines but did some modifying.
