The MOVA 1000 LIDAR, set to avoid obstacles of 20cm, sees Plantain stalks (Plantago major) of 15-20cm as obstacles and therefore does not mow the area where they are present. The sensitivity of the LIDAR should be adjusted to not consider very thin obstacles (less than 2mm) as obstacles.
Hi XB166498,
it is a good suggestion, but keep in mind that the manual said: "Use a push mower to mow the grass to a height of no more than 10 cm."
So these stalks should not be present. I suggest you run the mowing more frequently.
