I bought a Troy bilt rear engine small mower for residential. I have only owned it like 3 years I bought it brand new at Lowe's. Lowe's says they don't carry that model anymore so I called Troy-Bilt to get some troubleshooting done. To no avail. I had a lawn mower service come over. And spent another $150. And it still is the biggest piece of crap I've ever bought. The first one I bought and was delivered you put gas in it and it poured right out the bottom. They brought me another one and this one has gone downhill since I bought it. I think you should back your products and help the consumers lawn mowers should last 10 12 years this one hasn't even made it three and a half.
