I ran Yarbo for around 40 hours to mow a 3.2 acres garden.
But I wonder if this is normal. The discs seem a little melted and the plastic sticks to the blades. It prevents them from turning and also the edges are covered so they are dull.
I read a lot about the disc issues, but I wonder if this is normal behavior. At this rate I need to change the blades very often and even the new ones that I have installed do not swivel well since the disc is deformed (melted) from before.
Further Yarbo is doing a great job but this seems odd to me.
That looks like normal grass goo. You could use a mild detergent and a water hose to clean up under the deck with a soft bristle brush. You can remove the discs and blades and soak them in so dawn and or alcohol to help dissolve it. Are you mowing frequently and do you mow when there is dew or moisture on the grass? This can cause this that happen more. It is also very normal for grass to get stuck underneath the blades and make them stick in place, but they almost always stick outward in a permanent fashion. I’ve been able to spin mine by hand to free the debris and get them spinning again.

Thanks Bryan,
But it is not grass goo, I think. If you look at the blades closely it is a black type of plastic (like from the discs). And it really sticks to the blades.
I mow frequently.
Also the discs look a little deformed (like melted).
Or can all of this be caused by grass goo?
I understand the grass stuck underneath the blades, that is normal.
Photos don’t always do things justice. But from the looks of it to me a good scrubbing with a soft bristle brush, a mild detergent, and hose might clean it up or show the melting better, if that’s what it is.
Out of curiosity, what is your cut height at?

Hi Bryan,
I cut at 3.0. I will try to take better pics if it happens again.
The goo on the discs is black, can that be from the grass?
Again, really happy with the performance, just wondering
Thanks
This is what mine looked like.
This was cutting dry grass from November to April.
This was cutting wet grass overnight a few days later.
This was after washing with just a hose.
This was many hours of cutting later. Probably 15 hours.
You can see the blackish goo on the blades. Pretty sure that’s because I was cutting later in the evening in high humidity. Plus the grass is growing more now. That goo will come off pretty easily, at least for me.

Thanks for the images Bryan.
I replaced the blades and will check in a few days how they look. I have a big yard so Yarbo is working a lot
I let you know.
But the info you provided helps a lot.

No problem. Let us know how it goes!
Can it be the difference between running blade guards and no guards?
Tim
Blade guards will cause more build up and the build up in certain grass types and situations. So it can cause more issues. Yeah, it possibly could.
I covered the whole deck and both sides of the disks with SLIPplate which is a graphite. Not much sticks to it. Once a week I remove the disks and clean them in an ultrasonic cleaner which clean the last bit of the disks and blades.
