Well tried again, 10th core, so far it's a huge miss

Just received yet another rebuilt core, yesterday. 10th core in around two years. So far, no GPS, no Halow, constantly going on and offline by it’s self, no app control of blade height but works with physical. Don’t know what else I’ve yet to find, still reloading.

Sent me 2 flexible RTK mounts but with only 1 set of screws to mount them with.

Received an email saying:

"We’d like to share an update regarding your refurbished Yarbo Core under warranty exchange.

To ensure every unit arrives in the best possible condition, we have implemented an additional round of thorough quality inspections before shipment. This has slightly extended the preparation timeline, but it allows us to deliver a more reliable and consistent experience."

Apparently bowing smoke. Had to wait weeks for this core. Is Mother nature supposed to wait for Yarbo?

Ticket #195004

Did you do a map download and restore and then do a “replace data center” and correct for map drift after? What app/firmware are you on?

And I thought 5-6 core replacements I have been subject to is extreme. 10 is just nuts.

I need to report this to my wife. I must be finally doing something right…

Yes, did the download and restore. Is it safe to do a replace data center with no core GPS?

I half wonder if all these core replacements flying around are just an easy substitute for real troubleshooting. Were they really all hardware failures or just that they couldn’t figure it out and did a swap?

I’m on my 1st core in year 2 with 4 acres. I can’t just be that lucky.

Does your core show satellites on L2 and Total? Can you post a diagnostics screenshot of RTK, status, data center, and halow sections?

Yes, I think it’s probably a lack of experience on the support side that leads to the swap. But it is also about trying to get the user back up as quick as possible and I am sure if the user is extremely frustrated and taking it out on support that might be a factor.

I have 2. One from October 2024 and one from August 2025. Both are good.

Yep, your OLD DC and rover are not paired. It is safe to do a replace DC in the app. Replace won’t wipe your maps.

Sorry, wouldn’t you be frustrated? I’m 69 and bought Yarbo to simplify my life. So far it has made it exhausting. Having to chase, wait on tech support, unpack, reconfigure (started with no cloud with first 4 cores so had to re-walk all areas), test, repack and ship, has turned into a lot more work than mowing.

Just reconfiguring the settings and plans for each core, since you have to mount each module separately, takes 5-6 full days, before you can start.

Thanks, I’ll replace the DC.

Yessir, I would be. Hopefully this is the core for you and we get you up and going.

Great news, that corrected my Halow and GPS problem. Still have no control of blade height with the app.

Thank you very much, well back to reconfiguring.

That is good news at least for one problem. Ok, blade height control. This app change is finicky. You have to tap and hold until you see it hit the right setting and even then it may take a few tries. That’s something they are aware of and it will hopefully be fixed or refined in the next app release. Does it at least take your setting in the area settings and mow at the right height then when you send it out on automation?

Hi there, we’re very sorry to hear about the experience you’ve had and for the inconvenience this has caused. We completely understand how frustrating this must be, especially after going through multiple core replacements and waiting weeks for the replacement unit.

Regarding the blade height control issue, the case has already been escalated to our Field Service Engineer team for further investigation. They will continue reviewing the logs and system behavior to identify the root cause and help resolve the issue for you as soon as possible.

We truly appreciate your patience and understanding while we work on this for you.

Now it won’t calculate a plan. This is what I will lose.

Disabled DS pathway offsets and at least it starts to run the plan. Got a lot of funny errors including vehicle parking blocking path. There is no vehicle parking in front of DS pathway, it had moved forward just off the DS.

With the amount of NGZ’s I see, offsets are going to cause those weird issues I’m sure. As for the other weird errors, disable obstacle avoidance on the problem pathway setting.

I am seeing red all over this map. Mine is so boring, only like five no go areas total in five acres of lawn.

It is now working, but not adjusting blade height. Permanently a 4".
