I bought my Tiger Cat used, forget which year it is, but it only has 180 hours on it. A commercial landscape buddy says it should be good for 2900 hours. I am slowly clearing the understory brush on a heavily wooded 46 acres; using the Tiger Cat to mow the cleared areas a couple of times a year while establishing Buffalo Grass, food plot and wildflowers. I'm 60 years old, so it is doubtful it'll hit the 2900 hours in my lifetime. This machine rocks using Ethanol free premium gas.
