Today got the blades blocked alert and when inspecting, found out that there are lot of things winded on blade motor shaft. Had to unscrew everything and it was hard to get some grass and agrotextile threads out of the tiny space between shaft and motor housing.  
I’m wondering could there be any solution to prevent something from winding up there? Some sharp extra guards so they cut anyting that is aiming to wind up there?

The pro discs I believe have some raised plastic to help with this. And while not officially recommended or supported, I am pretty sure they will bolt right onto the M1. The plastic discs, not the straight blades.

Where can one buy those pro discs? Can’t find them in yarbo shop.

And do they really fit?

I’m wondering why they say that capital ONLY there.

Maybe they are heavier?

They are definitely a bit heavier. But also a lot sturdier. I would certainly use them at your own risk if you decide to go that route. If not, may give you some ideas on 3d printed options/solutions.
