My first troybilt I had for 12 years only problem I put a new drive belt on it then the deck rusted through so I bought a new troybilt the 21" 4wd walk behind first day using it was on a bank and it leak gas out the side. I have had it for 3 years and I had to get a new pull string, have bought 2 new gas caps and as you're mowing it leaks gas out the top and the gas cap will come loose. This should be a zero or even minus stars but you have to give them one. Don't waste your money on a troybilt mower I never will again!
