North Central Illinois
With it being an integrated globe, the lateral off set should be 0 from factory like stated in the other comments. If you are having issues with having to shift your lines, there are two things I would look at. First would be make sure that you do an Advanced TCM calibration and that you are indeed running in the same tire tracks when you go up and back (in the same track and not off to one side.) The other thing I would look at (since you said you are running in rows) Is make sure that your track spacing is set correctly. I'm not sure what size booms or what your nozzle spacing is, but if you have a 120 ft boom with your nozzles at 15-inch spacing, the factory track spacing will actually be set to 121.25 ft or 97 rows 15-inch spacing. I always tell guys to go into the Rows on your track spacing and just set it to 48 rows 30-inch spacing. Yes, it will say you have 1.25 ft of overlap, but for running in rows, especially if you run any sort of Auto Path (Boundaries or Rows) the system has to be set to how many rows you are covering and row width.

I hope that helps.
