I was cutting a few by myself in the neighborhood today, since i'm ahead of schedule. I was using the mulching plate on my 21". I always do this this time os season. Another guy who works in the area, stoppped to talk with me, no big deal, I'm friendly with everyone. He then starting telling me i'm making a big mistake mulching, that i'm going to regret it. he said they won'y be green for long, and that i'm building up thatch. i wasn't leaving any heavy clippings at all, you couldn't see a thing. now he's got me wondering, if i might be better off going back to bagging this time of the season. what do you think? keep in mind I thatch atleast once a season anyway.
