I’m not exactly sure if I should call this a bug but I’ll explain. A lot of towed implements that I use have relatively long hitches. If I paint my outside headland pass and create a boundary from it, then create a boundary curve, it works ok except that the tractor is then trying to drive based on where the implement was. So in tighter curves, the implement trails even tighter creating a miss or a fence post knocked down if I’m on the outside pass. I have tried recording a boundary while driving which works better but then the issue is that on these same curves, the implement crosses beyond the presumed boundary, which in turn will shut off section control. I’m wishing the boundary would be recorded offset in relation to the real position of the implement, and at the same time be able to record a boundary curve guidance line based on the position of the tractor/antenna. Or is there a feature in place that I’m not aware of?
Suggest you make a video to explain your issue clearly.
On the screen you setup section widths there is a setting that only turns off a section when the whole section is outside the boundary.
I can check that setting but in my opinion the boundary should be created based on the edge of the working implement.
Thanks for the suggestion. It could be a workaround. However, if that is adjusted so it doesn’t shut off on the headland pass, then when going back and forth, it will be prone to turn on at the headland turns if the edge of the implement passes too close to the boundary.
set the boundary setting to half implement width
I do headland first, then toggle that setting.
Would be handy to have that icon on the main screen to save hunting through the menu to find.
I would say the boundary must follow the true field boundary and AOG can do it if e.g. you record the boundary as if the tractor itself was the implement. You only have to do it once, not a big issue if not doing it while working on the field.
You cannot fool the boundary to avoid the curve line steering issues. AOG steers the tractor according to the wayline, just like the majority of commercial products do (almost every one still a few years ago). Ideally the tractor should steer according to the implement line like some commercial tools do. I believe AOG has some activity to implement that feature too but it is a very complicated task when working with a single antenna and no active tools steering (usually with a second antenna at the tool).
I wonder what sort of field work are you doing if you prefer 0% section control overlap? At our farm we use 100% coverage for every task, including seeding.
Perhaps a recorded path could do if you insist on a trailed implement following the exact boundary path. Even there you have to do it individually for each implement and you need to drive the same direction every time.
Using the standard boundary tool it will record from the pivot point as this is the only known accurate point. The implement position is only estimated.
If you want to use the implement coverage to draw the boundary you must use the “reverse pacman mode”
To use it make your first pass making sure you’re painting on the right spots.
Once you drove around the field, use the “create boundary tool”
Use pacman mode and record AB lines while driving your first pass.
On curves you will always have misses on thight curves. That just mathematical, eash curve is a working width appart, on curves your tool is at an angle to the working width so it can’t cover it all.
Three solutions: set an overlap, lift and turn around on thight curves or drive by hand.
I don’t think the curve calculation will ever taking in account the heading change to reduce the working width, this would also give dedicated lines for every tool, even they are the same width, giving completely different path after some passes.
It would definitely make AOG more difficult to use as this would be one more setting and you don’t want to mess it with row crop where you want the same path over the whole field even you have small gaps on curves.
