I started back planting a couple of days ago with a JD track tractor using 2600 and 3000 reciever on SF2. I had to offset the antenae 3 inches for the backrow to line up. This system worked perfect planting corn a month ago with no offset. Not sure what happened. I use a mounted planter and the lift arms are shimmed very tight. Just one of those GPS things I guess. I keep expecting it to shift back some time.
