The machine runs fine and is very easy to adjust the working depth, the lawn scarify excellent and fast, especially when meaningful work width for larger lawns (like us) very pleasant.
Sure, the grass bag can be omitted safely, at least for us, because it was full already after a maximum 5m. a gößerer would only marginally bring more relief, since the ways of disposing indeed still must be run. So catch bag off, after raking everything together and wegkarren with wheelbarrow ...
All in all a purchase, I have no regrets. You get really a good device for his money.
