Do you have a part number for the shield? My dealer won't honor a warranty claim so I'll have to buy it...
maybe i'm missing something, but how did the exhaust burn your grass??
I guess burned was the wrong word to use. It dehydrated the grass under the muffler where I had parked the mower. It would take a couple of days for the spot to show. The spot would green back up after a week or so.
