Hmm. I have not noticed this, and I think I have been stopping a fair amount while mowing. I'll keep a closer eye on things and let you know what I see. dlh2, are you still pleased with your mulch kit? I'm happy with its ability to mulch, but I still get a fair amount of clippings that settle on the black shelves / baffles that were installed as part of the kit. When conditions are very dry and I'm following the rule to cut no more than 1/3 of the lenght of the grass, it's not too bad. This is sometimes difficult for me, as my grass seems to grow beyond the 1/3 rule in 2 - 3 days (especially after fertilizing). If I mow after 5 - 7 days, there is very severe clumping and packing in all the nooks and crannies under the deck. I'm looking for a convenient way to have better access to the underside of the deck so that I can spray it off after each mowing. I'm thinking maybe of jacking up the front end of the mower to see if I can powerwash the deck. Any other ideas?
