At this point in time, I would not want a bigger header than a 8 row for compaction reasons. We can fill the combine with an 8, albeit we have to run faster than I would really like. We have 1050 Michelins and run 17-18psi with a 8 row and standard bin extentions, I do NOT want to run more pressure than then. For a bigger head I would have to go to 800 duals, and that is less pactical for road travel and storage.
