Ok, It's a Husqvarna 55R21HV. Here's the info on it: http://www.maximumoutdoor.com/new_vehicle_detail.asp?veh=35643&Manufacturer=40 Got it used, it's set up with a door that can be left shut for mulching, but has a bagging attachment, and a side discharge chute that can be put on. My inclination is to use it as a side discharge setup simply because I don't think I mow often enough to mulch. I need to mow more often to mulch right? If I'm going to discharge, is there a blade I should be using other than the one that came with the mower? What should I look for? I have no intentions of bagging, I think I'd have to empty the thing twice each time I mow, and don't want to mess with it. Thanks.
