Trimble XCN 1050 problems

[GlennW]

We have a Trimble XCN 1050 set up fitted to a JD 6830, predominantly used for spraying.

It picks up and follows an A/B line for so long, then seems to drift slightly then give the wheel a handful to get back on line, causing it to oversteer the other way, ending up with it swerving from side to side trying to correct itself.
The only way to stop it is to take control, get it back on track, and re-engage.
Other than changing the steering aggressiveness setting, which doesn’t seem to make any difference, is there anything that could be done to stop this happening ?

Or could it just be that it can’t cope with forward speed used (12 - 14kph)

Think there is another setting in 'advanced setup' something like 'p or d gain' setting. Had to adjust this but that was on a trimble new holland.
When did you last do a roll calibration? Is it a new problem or 1 you've always had

 

[GlennW]

It was fitted for last autumn when we went DD and stopped putting in tramlines, I didn’t do any of the pre ems last year, so just getting to grips with it this year.
It could be related to forward speed, but i’ll be disappointed if it can’t cope with 12k

It should cope with that speed easily enough. Used a trimble on a nh with a 6m trailed drill at 15k forward speed and always kept on line.
Am sure its just a setting something that needs tweaking a bit.
Is it a brand new system, have you tried your dealer?
@Vantage ASC - Richard is knowledgeable on these systems i believe

 

[GlennW]

Yes, brand new when fitted, it is NH software fitted by our local dealer, i’ll have to get on to them and see if it needs calibrating or something

 

[del_boy]

Definitely start with a fresh calibration, quite easy to do , follow the instructions on the calibration screen step by step.

Thanks @Del Boy, yes I'd definitely recommend going back to basics and complete all calibration stages. @GlennW If you don't have any luck with your dealer give us a call 01480 861824 We can complete a vehicle health check which would include the calibration for £99

I’ll look into it, many thanks

Did you get your problem sorted @GlennW ?
I have a nh t7.185 with lemken 30m sprayer on it doing the same thing. Sways back and forth to the point where it just doesn't work.
Tried P gain and Aggressiveness. Looking into the wear on the steering rams next.

Any assistance greatly appreciated.
Front tank changing weight doesn't help I know, but it isn't right at constant weight either.

@Bomber101 had issues I belive, don't know if they got sorted on another thread.

Got the dealer to it, and had it recalibrated, it is better but still has a wobble occasionally, I can’t help but think the yaw from the sprayer boom must be a factor
