I have used Toro Recycler Mowers for years, with no quality of cut issues, even when the recyclers were an "add on" from the dealer rather than factory installed. My neighbor, walked over and asked me why he has to cut his grass twice with his Honda recycler mower. I looked underneath it, and I see no Kickers like Toro uses, just what looks like one blade bolted to the bottom of another with about a 1" gap between them at the ends. Is there anything special that has to be done to this mower to make it cut cleanly? The lower blade was sharp, but the upper one was coated with grass. I assume that the upper one catches loose clippings cut with the lower one to perform the recycling process. Any ideas as to why this mower would leave so much grass uncut?
