We have a lot of thinking to buy the wolf pendant Verticutter to scarify our ca. 150sqm large lawn. The scarifying by hand is exhausting and time-consuming, but the unit is exactly for such a use the correct device. It gets just about everything dead material from the ground and the weeds could be removed fairly decent. Because our lawn had in the border area partly very mossy surfaces (presumably the grass was hardly maintained the last year), these areas were also significantly more thinned than other surfaces. We hope that this area regenerated (possibly through reseeding) again. The scarifier makes a stable impression, long roots and stones are not harmful to the blades. After the first use, we can use this machine, for all this love physical exercise and have to scarify a small lawn area, highly recommend.
