Re: Trimble Guidance Issues

Make sure that the GPS source is set to WAAS 138. If that is set to 138 then check the vehicle setup, starting with the angle per turn. Default will be set at 20, for most early magnums it might vary between 20 - 22 or maybe a little bit lower, on the John Deere side this value will vary between 15-25 depending on model of tractor. Also check to see how the T2 is mounted. Make sure that is flat and mounted solid to the floor or on a steel mount of some sort. If the T2 can move just a tiny bit it may cause the steering to wander.
