Subject: RE: John Deere Turn Automation

WC MN & Valley of the Sun, AZ

Grabbed some photos today of settings and since not in the field, and didn't have the engine running, couldn't get one of the display showing the turn so made up a graphic at the end showing how the planter makes a nice graceful 180 degree u-turn. Find doing a light-bulb style turn is unnecessary unless one is using a smaller width implement and in those situations, I just tell the turn automation to skip a pass to maintain a perfect 180 u-turn.

Note: These are with 132' headlands and DB44

Auto Turn Aggressiveness is 125. Very rarely go below 100 even on tillage tractor as it's too lazy. Have found over the years that higher turn aggressiveness in general is better. Usually never change it off of 125. Want the tractor to crisply turn with authority, not diddle-dally around in a lazy turn.
Start Turn is 40' into the headland. Gives the row units time to raise up out of the soil before the turn starts.
Max Turn Speed is 4.5 MPH (usually keep it the same as the speed pulling the implement down the field, turn at 8 MPH on the ends when doing tillage at 8 MPH)
Max In-Field Speed is 5.0 MPH
Minimum Turn Radius is set to half the implement (22' for DB44, 15' for 30' VT, 20' for 40' digger, etc.)
Max Turn Angle 90 degrees. Was surprised to see I had it set to 90 degrees, if planting tomorrow, would probably back it off to 85) When turning as sharp as possible by hand, look at the angle between the tractor hitch and implement drawbar, on a DB44, can get it pretty darn close to 90 but not quite. Max Turn Angle of 60 degrees definitely is too little. Never had any luck running that low of angle on any towed implement, tractor will make too big of a sweeping turn which is unnecessary (see above).
Enter Headland is set to go 12' into the headland before raising the planter
Exit Headland is set to -33' to drop the planter before the edge of the headland. Works near exactly perfect for the planter to set all the way down about a second before the row clutches activate to start planting.
