I scarified the lawn and it was a breeze! It was pretty easy to put together, the instructions were handy. I like how you can adjust the depth which was very easy. Scarifying the lawn was simple: just press the button, squeeze the handle, and gently push the scarifier where you want it to go. It cuts through the stolons of the grass, and I’m probably going to run it over the high spots too as the lowest setting does a pretty good job of beating up the top soil when running over the same spot for a minute. Very nice tool, 5 stars!
