I had been with a Vertikutierharke - ie by hand - scarify and occasionally rather than regularly. Such was to be processed green space - even lawn would be well-meaning, to say nothing of turf all - also made. In this electric Verticutter I ended only after several purchase attempts. The previously selected devices or by Wolf Einhell a number were bigger overnight sold out or become more expensive by 30. After the first use to judge these spare replacement solution was a complete success. The scarifier has a decent working width and gives right on. But I thought I would actually use a plow, the Einhell Verticutter has struck more than wacker. To the issues raised in the reviews catch tray I say nothing. I have it as is safely removed from the preceding sentences, not even attached (as a former "Hand Scarifier" makes me raking nothing). A final sentence for installation: Simple, fast and without tools. Conclusion: Highly recommended.
