Okay so obviously you cut some tall and dense grass. What level of height setting did you have the mower adjusted to? I have this mower on its way to me and I am going to test it on my yard grass. I will measure the height of the grass and note the height level of the mower when I start. From your video it looks like it can easily pack the grass catcher so it must have great ability to generate good airflow under the deck and elevate the grass clippings into the path.

How well does it mulch?
