How long should a good trimmer last these days? Replacement recommendations? I'm using a Stihl FS 80 specifically for my residence, (no longer have the business) only bought new in '04. So it has seen just under 6 seasons of use. That said it was only used maybe 10 hrs a season so it has 60 hrs on it w/ basic yearly maintenance end of year and is crapping out, won't start or stay running now requiring a new carb, lines etc. While that seems old time wise, hours wise I'd consider it a baby if I were using it professionally. At roughly $350 that's almost $6/hr to use. I'm wondering what opinions are out there for how long a "good quality" commercial trimmer "should" last in years / hours used under "normal" conditions with appropriate basic maintenance before you start having major issues and/or repairs? In general, after how many years/hours would it not be worth repairing vs. replacing even if replacing would obviously cost more. Also, any recommendations on a replacement vs having it repaired, (roughly $130 for the new carb, lines etc. I'm quoted) I do the regular trimming plus heavier / taller grasses around a lake front every few months and some wooded area underbrush trimming a few times a year occassionally using the 8-tooth blade.
