Tool Steering

May I drop into this venerable circle, please?

Germany. Organic farming. Side hills (really ones). Hoeing crops.

Tool Steering

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 i…

I’m on of the guys beyond the 95% fence

Hoeing is done with a venerable Fendt carrier aka “Geräteträger” F275.
No problem to manually steer the hoe in the middle of a GT to ± 3 cm precision at 8 km/h, 20 % side hill, 50+ cm crop hight, undulated by side wind for 8 hrs a day …

Schmotzer sales clerk at Agritechnika 20 years ago:
“If you have a Geräteträger, then there’s no way to sell you a camera system”
(So, I got a second one, then…)

Following seed tracks by GPS would be “nice to have”, but only 2nd priority.

But you can’t hoe properly when the seeding is crappy.

Some images what should not happen:

Account for reduced effective tool width at side hill

No, I did not produce that sh… today just for you. Sh… happens, that’s what sh… is for (Murphy’s laws) And it happened already at seeding, hoeing today just revealed it. So you see, why I desperately need GPS - my manual steering is far from perfect This is what happens when hoeing seed overlap: clogging of the hoe’s tines [grafik] And this stripe of weed remains when the gap is too large [grafik]

So seeding at ± 5 cm would be great.
Current machine is a trailed Horsch DSS2 (pictures are close to mine)
6 m widht, 22 cm row spacing, ~ 6m trailed length.

Early design when in the 1990ies, Horsch shifted with their 3-wheelers to double disc seed coulters.
A trailed seed container (replacing the 3-wheel trac), with a 3-point-link that carries the seed bar.
(will take some photos, promised).
So may be that would be an easy point to introduce tool side shift.

So my idea was:

• rough steering on the tractor (JD 6530 premium autopowr)
  (maybe 1 receiver and IMU or dual receiver UM982 dual antennae)
• fine steering on the seeder aka implement
  I’d attach the two antennas of a UM982 at the far out ends

I’m still early in testing and learning, but that was what I had in mind 15 yeras ago when I realized 2x dual antenna multiband RTK was far beyond budget.

5x AOG board from JLCPCB are waiting for test, as is a UM982 board. Antennae I hope to arrive yesterday…

I’m not afraid of some fiddling, coding or development versions, although I’m much more familiar with linux sytems than I am whith Windows and embedded arduino style gadgets. But I think whith some guidance, I can cope with them, too.

So how to proceed?
