I only used that once the Aerator on a plot of 550 m2 (house included) so about 350 m2 of lawn and it is perfect for this surface. As I had not spent a scarifier long time, I removed the tray and then spent the mower to pick up the foam and abundant grass. Although it is not very large compared to other products, it is more than enough for a lot like mine. 3 weeks after scarifying the lawn is already very green but then she enjoys the rainy weather we have right now, unlike us. I have not tested the aerator, but I am confident. As always, delivery by Amazon was fast and perfect! Finally, if you hesitate, go ahead, this is great!
