Short blade decks don’t seem to cut as well as longer bladed ones.The speed seems to have decreased from 4.1 mph down to 3.8 mph? Hopefully, the new engine cures the power issues. I still think the size of the deck is a problem too. It's too short both in length and height. I don't think the clippings have the time to circulate properly before hitting that deck. In addition, it's a flat deck. That lends itself more to side discharge rather than bagging or mulching.
Your forgetting the fact that a single blade 30 is the dumbest thing ever created if you mow irregular turf , mow short and own a tape measure.Definitely agree on this... The single 30" blade Sarlo Big Mo leaves one of the better cuts of any mower I've ever seen, regardless of deck size.
