Your design is great and better as an option. Just hoped someone will crete exact replica of pro’s mulching blade (not disc) to be used on non-pro model. The Yarbo reason for not releasing pro mulching blade for non-pro mower is motor and redesigned deck but if we can create with plastic with razor blade edges, that should serve the purpose with lift.
Impressive. Very nice work!
Will be interesting to see how the blade holds up under normal use without hitting any rocks. I’m wondering how long the end stays sharp over time.
Me too. I’m actually surprised the plastic stayed sharp at all.
Then the question is, how sharp do they need to be ?
That’s really cool how well it worked with a plastic blade!
I would have thought that with the mower normally using ‘razor sharp’ razor blades, the blade would need to be super sharp to be effective. Now that I think about it, I guess normal push mower blades aren’t razor sharp and they work just fine.
Maybe you’re onto something!!
Looks great. I like @soofia idea of modeling the pro blade out of plastic. That’s the best of both worlds for the original mower. @Yarbo-Forum this is something Yarbo should consider for the M1 users as an optional blade. Won’t be as powerful or robust as the Pro but will offer the same cut and lift for most lawns. If you need stronger and more reliable and powerful, go pro.
There are four blades at the end of each strut.
The disc’s can also be switched to the opposite sides.
The the whole idea of plastic mulching blade with razor as edges is to lighweight and create a lift for slightly wet grass. Not expecting same performance as pro but would be better than no lift cutting. The razor blades can be installed statically with wither 2 hole razor blades or plastic top holder.
I can understand if Yarbo doesn’t want to pursue this, since it technically defeats the purpose of the Pro module for most people who don’t even have much tall grass and are mainly looking for slightly wet grass lift while cutting. That’s why I suggested someone with 3D CAD experience take the first stab at it. I’ve only recently started learning Shapr3D myself, and I don’t have a Pro mulching blade available for measurements or comparison. On top of that, I’m not sure when my skills will be polished enough to design a truly functional part.
Is anybody using the straight blades?
I plan to print and anneal some carbon fibre nylon to see how it performs in this use case. Sorry I didn’t get the 3d scan done this weekend, time got away from me. I will try to get it done this week.
Edit: Apparently my 3d scanner no longer wants to do it’s job… ugg. Hard way I guess.
If it isn’t too much trouble please would you be able to scan the tow hitch plate so I can check it with my adaptor? My Yarbo has not arrived yet so can’t measure myself. Thank you 
I will give it a try, but my 3d scanner doesn’t want to work for even basic things atm. I have an einstar and they are decent - but I need to figure out what its deal is here.
Here is the cover for the straight blades - when I confirm the model actually fits I will put it up on Makerworld.
You can expect that there will be updates to the model as its built out - but starting with a factory clone is not a bad place.

Looks nice !! Can’t wait to hear the results.
I would like to have something that is swappable and not dedicated directionally like the default blades are.
Know the feeling 
I don’t have a scanner but if I remember 
I will measure mine.
Agreed 
appreciate the efforts
this looks great. it would be perfect with little twist or end angle wings for lift and place to mount razor blades on the cutting edge. BTW this looks great for first cut.
