WildBuckwheat - 6/3/2025 20:00 All GPS systems use true north, they don't use magnetic North. The difference is in the projections. A 0 degree John Deere line will cross the center of the North Pole, so will the passes beside it. Your passes might b 30' apart here, but they'll overlap completely if you drive to the North Pole. AgLeader/Trimble/Everyone else doesn't do it that way. You can set your deere straight track to use different calculations. It's set to Deere by default, set it to non-john deere 2 to match AgLeader/Trimble exactly.
