I don’t remember my snowblower making any weird noises when I first activated it either.

The aluminum belt gears are noticeably pitted. Likely from debris and oxidation. They appear quite soft and easily damaged.
I will likely inspect them and the internal transmission gears as part of my summer maintenance. Has anyone ever done this an reported their findings in the forum?

All this being said I still love the product.

I’m planning to pull Yarbo into the garage tomorrow for some PM and a thorough inspection. Probably about time I grease the tracks…
And yes, I think Yarbo is a great tool. My favorite robot of 2025.

Hello there. I have had the issue twice now. The first time a replacement pulley and belt were sent and the same thing is now happening. What seems to be going on is that under load, the entire motor rotor retracts backwards causing the motor pully to scrape up against the bracket. I have removed the blower while it is wedged, and can see a large gap on the motor rotor. I spin the auger backwards by hand (takes a bit since its wedged!) and everything snaps back into place. Does anyone know what’s supposed to keep the rotor in place and not back out? Is there a snap ring or set screw? That seems to be the root issue for me.

Get a ticket in. Sounds like you need a new motor.

Take pictures. They replaced my 2024 unit with a 2025.

Hi there — sorry to hear you’re running into this again, and we apologize for the inconvenience. Could you please submit a support ticket for this issue so our team can investigate further and help you troubleshoot?
Thank you. I have placed a ticket in and at this point they are ending another pulley and belt, but its not solving the root cause of the issue.
Thank you. I will do as you suggested. I took pictures but not a video of turning the rotor.
