The Yarbo was mowing fine and then I noticed it was stopped with a “Left Cutting Motor Blocked.” I cleaned it thoroughly, cleared the code and tried again. Lasted a few minutes and then threw the code again.
There is a lot more resistance when trying to spin the left cutting disc by hand than there is when trying to spin the right cutting disk.
I entered Ticket # 86148 on Sunday. Support got back to me on Tuesday saying they checked remotely and the machine was fine. I’m guessing that is because I cleared the code. I tried mowing again, same issue, I updated the ticket. They have me scheduled for time with the engineer at 7am on Sunday morning. My worry is that we will lose so much time waiting to diagnose something that points to a motor replacement. Then how long does it take to get the replacement part? I’m getting anxious about being down for weeks.
Has anyone else had this issue? If so, what was the outcome.
I’m definitely frustrated, this is when I need it most (like everyone, I realize). I was loving the yarbo, I’m coming down a little bit from that high, hope I don’t fall too far!
Take the discs off and see if there is anything wrapped up underneath. I’ve seen several people post about plastic bags, strings, and other random things getting wound up underneath and causing the friction.
Use gloves or an old towel to hold the discs and an impact drill and Allen key bit if you have it. If not, use the Yarbo tools. If the loctite is a little too tight, you can use a heat gun or hair dryer to heat it up a bit and help break it loose. This is really where the impact drill shines.
If there is nothing underneath and it still doesn’t spin freely like the other disc, then keep your support call. Take pictures and video of the above if you can and upload it to your ticket, it will help them diagnose it quicker and maybe even before the support call so you can get some of the time back if a replacement is needed.

Thank you, I appreciate the response. I should have mentioned I did take the disc off on the side giving the error and was not able to see anything stuck there.

The engineer did decide to replace the mower unit and shipped it out last week. I am scheduled to receive it on Wednesday of this week. Will be very happy to be back up and running!

Unfortunately, the new mower is throwing a “Right Cutting Motor Overheating” error. It ran ok one mowing and then started throwing it every 10 min or so.
Really starting to second guess this purchase. It was so nice when it was working. Now so frustrating when not.
Have you removed the blade guards? That can help if grass is building up and causing the overheat. Also check the spindle as something may have wrapped around it.

Hey Bryan, thanks for the reply. Yea, the guards were removed. Nothing in the spindle, unfortunately.
I want this to work so bad!! The clean lines, not having to waste time sitting on a mower, just amazing. My 3.5 acre lawn/open field never looked so good when yarbo was able to make the first cutting of the season and stay on top of it.

The birds are getting small nylon strings from somewhere. Almost looks like tyvek house rap. They are small “strings” of it that get wrapped around the spindle. I had to remove the mowing disks and the aluminum block they attach to in order to get it out. Once I got it out my overtime went away. Until Yarbo found some more. Happened 3 times now. But is an easy fix. 10 mm nut on the spindle if memory serves. Not sure of the torque specs to re-attach so I went with torquing until my eye teeth popped and a half a round more. 
Thanks Ken. I have taken the disk off many times but never the aluminum block they attach to. I will try that but Support did reach out and said they will expedite another mower replacement.
