Grass tends to accumulate under the cutting blades, and blades need to be manually unscrewed and flipped to make use of the other side.
To remove stuck grass, one has to manually spin the cutting blades backwards.
To improve the situation, could the mower change the spin direction on a regular basis?
This is how robotic mower competitors address the challenge. I hope Yarbo has the electric motor controls to enable this useful feature.
Thanks for your consideration
