Have I seriously damaged my mower?
Can anyone help please? When I was mowing, I ran over a largish stone. The mower made a noise like the stone was whizzing around with the blades then white smoke came out of the exhaust. When I stopped the mower, I tilted it up (only slightly) to see if the stone was still underneath, didn't see it but saw score marks where it had been. The blades still move OK. When I started the mower again, it sounded like a tin can and there was a bit of oil coming out of the exhaust. Have I done serious damage? What should I be checking next? The mower is only 2 years old.

The mower is only 2 years old. Pull the plug wire, and rotate the blade. Chances are, you will find that the crankshaft is bent, causing one end of the blade to be higher than the other. |

With oil coming out the exhaust after hitting a large rock, you have serious damage and it isn't going to be cheap to fix. I'd try to get a rough estimate over the phone on the repair cost range before spending money on fixing it. If it's a low to mid-range mower, you may be better off buying a new one and parting this one out on Ebay. Start with the engine and tell them you hit a rock and it no longer runs, all sales final, as is, etc. That usually gets people interested. I'm amazed at what people will bid on crap like that on Ebay. |

This is all dependant of what the machine is though..... if its a Honda with a Rotostop Clutch the crank could be fine but the clutch could be damaged causing the "tin can" sound? More information required please. Lawnmower World - The home of Quality garden machinery |

Depends what side the mower is tipped.

All I can guess is a sudden change in crankcase pressure to the high positive is causing oil to blow past either the rings or valve guides and blow out both ends...kinda like when you cough and f@rt at the same time.....it happens....Midnite nuevolawnandgarden at verizon dot net nuevolawnandgarden.webs.com |
