The system operates as rotary scissors. A fixed blade on the frame meets a curved blade on the red scroll, and it cuts the grass net. For a clearer cut, taking into account the wear of the blades, we can adjust their spacing with two small wheels (see photo) without tools.
3 cutting height are preset (tools required), but you can adjust the height is desired.
She walks impeccable, but I think that we should not have more grass 50m², unless you want to make :) muscu.
Only downside: if the grass is too high, it will not work, the grass will bend too. It is imperative to make several passes at maximum height if the grass is high, or spend a traditional rotary mower, before doing the interview by clearcutting.
The product corresponds to my expectations (I have a small garden that I speak regularly), but I think if you have a large garden, or want to space your clippings up, it's not appropriate.
In short, you have to buy a mower tailored for his use :)
