I've been running the JD turn automation for the last 3 years.. Pretty slick, not only does it automatically turn at the headlands you can also set whichever scv's you use on the headlands as well(up/down shanks when entering,leaving headlands, etc..) and controls tractor speed slower or faster. JD had this feature for a long time previously known as the iTec but much easier to set everything up today than the iTec days. Takes a bit to get everything setup but basically just need to be accurate with your tape measurer and offsets. That and setting up your boundaries for each field which you will need at least SF3 accuracy. Was it worth it? In my mind yes, especially since I was already all setup with the GPS equipment. I have a seedmaster/Bourgault setup, for those who have that setup know there could be up to 4 switches you have to turn off and on at the headlands. Now I only have to switch packing pressure off and on, the rest does it automatically while turning. Which you can check your drill/tank thoroughly while it turns itself. We all put big hours during seeding time and sometimes forget a switch or 2 due to fatigue. This basically eliminates that whether its you or the not so much skilled operator in the seat. I've been doing all the seeding for the last 20 years, since adding this setup my brother and dad who is 70 years old are finally seeding again when needed. They are much comfortable in the seat knowing they have a much lesser chance of forgetting something. Just that in itself is worth something.
