In the international Telegram group Brian wrote about that passive implement guidence there I asked about the idea of a passive curve compatation like at Fendt VarioGuide and also with a tool receiver was talked about in this situation.
So he was like if it need to be good in Curves and on slopes it would need to have a receiver at the tool. He wrote that only the calcultation like Fendt does and AOG uses fot painting is not good enough.
I heard pretty impressed users of the fendt varioguide in curves too(pass to pass in curves like described above)
So still the situation here with smaller tools in Germany is diffrent but we have kind of the same problems sometimes.
If you want to do Striptill at small hills and curves you need a system like the Deere f.e.
So they steer the slurry tanker with the stripper passive and still record the exact lines of the stripper were it was in reality.
The Planter has a kind of side shift which steers to these recorded lines. Planter and stripper have the same number of rows.
I guess if it should be really accurate you need sideshift so called active tool steer because passive will be to slow in this case.
This is the case for striptill or row cultivation and if you don’t record the pass of the implement also the first pass f.e slurry with stripper needs to have a shifting frame in the back to get it always were it should be because passive could be to slow and you would need to record it.
But at many applications it is not needed to have active toolsteer!
I agree with you even if I have no big clue of coding that passive tool steering should be much more complex to code but it is much more easy to use not much hardware is needed and the Trimbles and Deeres seem to work quite good also Chinese FJD will launch a passive and active Toolsteere they are testing it at the moment.
If you only want to have you Tramline at the right spot at hills or curves so you can drive through it the next pass spraying via autosteer or between the corn rows you don’t need to be that perfect in my opinion. So if it is only imported for Tramline and first pass at a curve if you recorded it via 3 point tool and seed with trailed one im my opinion active toolsteer is way over the top you need many extras to make it work like hydraulic valves a big frame and so on. Next problem is that at small tractor with a 3 point tool the frame adds weight and distance which will make it not work anymore.
Active implement steering remains a niche product for organic farming; in my opinion, passive implement steering covers 90% of the problems that really affect everyone who uses a steering system. These include good slope compensation, repeatability on curves, especially the first track with different implement types, and simple and inexpensive installation, as the hardware for AOG is quite inexpensive and the main cost driver would be two receivers, assuming you use dual on the implement.
So, to come to a conclusion, I also believe that a active and passive systems have there right to exist but passive is much more common and does solve many problems if it works fine like you here about the OEMs.
Due to its complexity with things like the possibility of recording the tracks of a passive tool like John Deere does or having a good code for passive toolsteer that all requires a lot of work and time I guess the guys who thought of passive toolsteering is up coming up were wrong because in the telegram group passive and active were mixed but maybe I am totally wrong.
The developers have already done a lot for all users; you just can’t expect everything, and even the commercial systems have points, in addition to the price, where you, as a user, say that AOG does this a lot better.
