I am going on my 9th year with my Ryobi trimmer. A year or two ago, the shaft broke and I replaced it myself, and this year the clutch disks broke and I just replaced them as well. I believe the clutch disks had actually broken long ago and the clutch locking up is actually what caused the shaft to break, but I don't know for sure. Now that I fixed the clutch on it, the thing starts just as easy as I ever could've asked for. Other than those two repairs, the only other thing I've ever done to it was put a new spark plug in this spring and put a little bit of sea foam in the gas the last 2 summers. Up until last year I never even specifically ran the tank empty or put fuel stabilizer in it or anything. Before I fixed the clutch it was getting really hard to start and I thought it was on its way out and I was contemplating what brand to replace it with - leaning toward Echo or Stihl. But as I've thought about it, if it died tomorrow I'm not sure I wouldn't go buy another Ryobi...
