| This year we are running the autotrac with SF1. I think you will be happy with it with an air drill. I used SF1 parallel traking last year to run our air drill and it worked very well. We just started planting today and we were using the SF1 autotrac with the markers. We had to use the shift track at times to keep it right on the marker, but it kept the rows straight. As far us upgrading to SF2 I believe it's more like $4000-$4500 to upgrade the receiver and the keycard, and if you are just going to autotrack, I would stay with the original system.
Good luck with what you decide on! | |
