I've previously inquired about the hardware store. The seller has advised me before I vertikutiere to treat the lawn with weed killer and only if it is brown einzusetzten the scarifier. Otherwise, he manages not to deal with the whole weed and it could overheat because they must maintain a high effort. This I did and again read me the instruction manual. There was, among other things, that new blades, the stage 2 is sufficient and the lawn should be mowed before. I cross and long scarify. In the first few times much green stuff has been in the pot and he had to be evacuated about 50 meters away. Otherwise, it is too heavy andthe pot depends almost on the floor and drive also difficult, since the V threatens to tip backwards. (To me does not happen) in the end he brought out a lot of earth, which is of course much more difficult and therefore I must empty it more often. If an electrical appliance not a thing that you throw quickly again. Press the button and there you go again. There have been roughly around 100 m² and I have brought ca 2 full wheelbarrow out. Now was also very much weed it and barely lawn. My partner said the result: The surface looks like geflügt, only a few individual tufts of grass are still old. (Who were also extremely firmly in the ground. Even pull out by hand was a little effort.) Seems to be a good scarifier. The ventilation roll I have not yet tried out. All in all, he has done a good job and I'm happy with the result. Next year I'll do the grass at the side of the house. It is also important to clean the scarifier. It had a thick layer of soil deposited.
I nacher somewhat loosened with a rake so that the lawn seeds may well the surface.
