I have a customer that I've been doing for about 3 years. Young guy with 2 kids and a wife. His wifes grandmother bought them a Snapper self propelled walk and an FS85. He owed me for 3 cuts and I joked that he should let me have that trimmer instead. Long story short, I got it and it didn't even have any green on it! Anyway, I've never used Stihl products before so I don't know if it's supposed to sound so loud? I mean it's really annoying. I'm used to my Robin and even wide open it doesn't sound like this thing. I've used Echo trimmers also and they sound annoying to me too. Anyway, I put a brush blade on it so it'll be my brushcutter/backup.
