I have a Lazer Z HP 52" purchased in 2001. We have had a very wet May and June this year and mulching was more like "clumping" than mulching. So I took off the mulching kit for a couple of months and that problem was solved. Last week I put the mulching kit back on with new mulching blades. Rather than being mulched, the grass blades just seem to be cut and dropped in the grass. Looks like I just blocked the discharge chute and used regular blades. We ended up raking each lawn to get it to look like we wanted. Mulching last year seemed to be fine. I first checked the mulch kit installation and it seems to be OK. Put on new blades and got the same result. Motor seems to be running at the proper speed (it sounds like it is) and was checked over the winter by my dealer. I put on the blow out baffle last fall for leaf muching. I still have it on the deck. Should I removed the baffle or am I over looking some obvious thing I've screwed up? Any help would be appreciated.
