This mower is about 5 years old and ran and cut great until I hit something metal in the yard. It picked up a vibration after that. I replaced the blade with a dull one I had kept, but it still does vibrate a little. Could be a bent crank, or adapter if you are lucky. I presume regardless, it could be fixed if you wanted to go into the engine. I don’t think there is other damage to the engine, it starts first pull and runs, just vibrates. Can hear/see run. Otherwise if you wanted to part it out, deck is good, back wheels are ball bearing. Mower can bag or mulch. 502-295-2811 Location: Louisville it's NOT ok to contact this poster with services or other commercial interests kentucky
