I have 310 with Pro 700 on v. 31.31. Hooked to a 2150 planter. Machine and swath width set to 720”. For some reason it is using a 725” swath width this season. I can not change swath width due to smart implement. Any suggestions? Have been on tech list at dealership for a few days, but I am running with markers and not that important I guess. Have done all steering and roll cal calibrations that I can do. Steering real well. Running RTK Glonass signal off of a 542 base.
