Thanks for all the advice. My mower does have a spring-loaded door at
the rear of the mower that stays down when the grass catcher is not in
place. I just sharpened the blade, but as was stated, I'm not sure if
the mower has enough power to mulch properly. It is a 3.0 HP electric.
It's funny because I've never seen an electric listed in HP, just
AMPs.
