Replaced my first set of blades. First mow was May 8th 2025. 2.9 acres has been mowed a couple of times. I’d give accurate numbers if the “work plan history” functioned. I’ll update if I can remember once that bug is fixed.
I’m not blaming Yarbo, my new to me yard has a lot of hidden surprises.
I had two blades broken before I replaced all 10 of them. I have gotten a few “Right Cutting Motor Blocked” messages.
Again, not Yarbo’s fault. He is very good at finding chunks of metal and larger hunks of sticks hidden in the grass. Hidden from me as I have walked the mow area several times and keep finding stuff that isn’t good for Yarbo. 
Just wanted to share.
All in all I’m happy with Yarbo.
