First have to say that Trimble FI combined with NAVII works awesome, especially when backing up into corners.

Now we have some problems to hold the line on autopilot. The sprayer keeps going around the line about 15 cm left to right.
We have the antenna on the cabin roof, about 4 meters in front of the rear axle. We can use 4 wheel steering, but on autopilot we select ( normal) front wheel steering.
Running at about 5 kmh. Anything set up properly.

Anyone any idee's on how to improve the Autopilot's performance ?

maybe we have to start with a different vehicle ?

Thanx

btw we have a tractor on autopilot too, which runs fantastic !
