Hi, first of all, I’d like to thank Brian and all the contributors for their work in developing this software.
Last year I installed Agopengps to plant my corn, but I ran into a few problems.
My tractor has a front-mounted fertilizer spreader, which puts a lot of weight on the front, and when the planter is lowered, there isn’t much weight on the rear axle.
This makes the tractor quite unstable in terms of roll and on top of that, it has an older-generation suspended cab that moves a lot from side to side.
I tried mounting the antenna on the cab, but it was a disaster, so I immediately moved it to the front of the hood. It worked but there was a lot of lag on sidehills.
This year I tried using dual antennas on the front and it’s completely different from what I’d experienced before. Very stable even in the worst conditions, good stability on sidehill, and really great on U-Turn.
I’ve made a few videos in the worst possible situations. I hope this will be helpful to some of you.
Thanks for sharing!
Do you have auto dual fix setting activated?
I have a dual system and struggle at sidehills (around 13 degree) with my corn planter to hold the line.
I have tried integral from 10 to 20. With 10 and 15, it kept going down the hill.
With 20 it made it back to the line and then overshot it, which lead to a wiggly line.
What i have observed was -
When driving on a sidehill, when i manually drive, all i (have to) do is steer upwards, as the tractor gets pulled down automatically. I never have to steer downwards.
However, the steering system first lets the error grow, then steer up the hill. As soon as it passes the line it starts steering downhill again (which it shouldn’t).
Did you try it at steep sidehills? For me, it worked fine for a 7 degree sidehill. But sadly not for the 13 degree sidehill.
I don’t have fields with moor than 9–10 degrees sidehill.
I don’t think positioning the antennas forward will make a big difference to your problem with extreme sidehill.
I benefit from good motricity thanks to the front weight and a tractor that is relatively large compared to the planter this can limit drift.
Front-mounted antennas may have an advantage on very uneven surfaces because they are closer to the ground and have less lateral movement when the vehicle rolls heavily.
Or when you have a very unstable suspended cab.
Or when there isn’t enough space next to the cab as on a self-propelled sprayer with a boom that folds up next to the cab.
