 The model I have is the SRD17530 (280020) 30" rear bagger and the mulch cover is installed in the discharge unit to the bagger.  The mower works just fine as long as the bagger is in place, but will not allow me to lower the blade to cut if its not.  Since I don't need the bagger any longer, and its adds additional length to my mower, it makes a difference in tight places.  I bought it from Sears and they are clueless. I did see in the left rear wheel well, an electrical connection and a place where the bagger trips a plastic ??, both close together on the bagger track.  Do I just need to unplug that and permanently trip the plastic thing to do what I want?
