I saw someone post this on Facebook and I had always thought that flat blades would be a nice option to try for smoother cutting rather than the slight lift and curve with the current standard style.
Yeah I wish Yarbo would offer something like this for the M1.
Thanks for sharing the design idea with us. If more users express interest in this option, I’ll help pass it along to our product team for further consideration.
Interested here!
Bad news here is M1 is discontinued so chances they want to spend money on making parts for a discontinued product is slim at best.
Dang, I bought it a month ago and it’s already outdated. 
Guess I should have ponied up for the Pro.
They will continue to support it, so no worries there. The standard mower does a fine job too, just not as forgiving with wet grass or tall grass, but it can deal with both situations with some caveats.
My yard is 3.6 acres so if I only mow when it’s dry (assuming it does not rain), I get about 1/4 of the yard done a day. By the time the Yarbo gets around to hitting the same area with the next mow, there is tall grass in areas that just gets pushed over. It’s great that I don’t have to hit nearly as much with the zero turn anymore but I’m interested in ways to reduce what I have to mow manually even more. I forsee a Pro head in my future perhaps next year but meanwhile I am looking at blade options. Sorry for the rant.
Yes, you explaining that is exactly why I have a pro mower and the M1 is put away and will probably not be used again. The pro is the answer to areas with heavy ground, and or get periods of rain frequently.
