BotaBXer, The dandelion fuzz accumulated after just one mowing in the spring of 2006. The engine temp gauge never showed any sign of overheating. The mosquitoes surprised me the most. It was last May during a cool evening of mowing. There were clouds of mosquitoes in the air. Since it was cool, I was wearing a hat, coat and gloves so the bugs never bothered me. Just before I put the tractor away for the night I got off to see if there was anything on the grill that I should clean off. Needless to say, I just had to take a picture. As soon as I shut the engine off most of them flew away.
