I have the same issue, my wife hit a rock and now the mower will start for a second then quits. sucks because its brand new. I checked the oil, the gas, the spark plug, the shaft is o.k., even took it apart to check the flywheel shear pin and that's o.k. called the local mower shop and was told to go get another one! basically, the damage is internal and would cost more to fix than replace. this is done purposely by the manufactures. they don't make any money if you buy a $1.00 shear pin, new engine is much more profitable. this is coming form the repair shop.

SOURCE: Mower hit a big rock and stoped running

If you hit something hard enough to partially shear the key on the blade adapter, you did shear the key on the flywheel, and it will need to be replaced for the engine to run properly.

The flywheel key has sheared or partially sheared which throws off the spark timing. Removing the flywheel and replacing this key will put the timing back in place. If the crankshaft bent at all you will feel a new vibration when it starts. As long as it is not to severe and the blade is not hitting any metal it is ok to run.

SOURCE: My wife was mowing the lawn and she hit a rock.

Unless the blade is belt-driven, like on riding mowers, then the blade is attached directly to the engine crankshaft. Hitting a rock with a mower like this is a very common problem. You probably have a bent crankshaft. In most cases this can be repaired, but may not be worth it, considering the age of the mower. But you should call a local small engine/mower repair shop to ask for an estimate. The repair is not something you would be able to do yourself.

SOURCE: Hit rock and stopped mower. The blade isn't bent or loose but the mower will not start. It turns over seems to almost catch but not quite

If it hits somthing hard enough it will shear the flywheel key, which will knock the ignition timing out, to replace the key you will have to remove the flywheel, there are special pullers to aid removal of the flywheel, these can be purchased from your local Briggs dealer.

While mowing with a brand new craftsman riding mower it sounded like it hit maybe a small rock and quit running. When you go to restart it just has a clicking sound


That sounds like a flat battery, faulty starter solenoid or starter. Hitting a rock would be coincidental to bad starting unless the stone kicked up and damaged a cable, but that should be impossible.

How to fix Mower cord stuck after hitting rock?


Pull the plug. MAKE SURE THE PLUG IS COMPLETLY REMOVED AND SEPARATED FROM THE MOWER!! Remove the cover with the pull start attached. see if you can turn it by the flywheel or the blade. If you can, you can just have the rewind repaired.
If not, then you have a probable bent or twisted crankshaft. Most likely not worth repair.

I hit rocks with my lawn mower on accident, and now it will run for a few seconds and turn off


This happens often. Sometimes your mower will start and run again and sometimes it won't. When it doesn't run it's because your timing is off, caused by a dented or sheared key.
To replace remove top cover to engine, and any other side attachments, this should expose the flywheel. Remove the top bolt and look between flywheel and top of crankshaft, you will see a small square notch. This is where the shear key is placed. Remove the flywheel and replace the shear key. Replace all parts in reverse order and you should be mowing again. GOOD LUCK.

Hi, you are correct, the key will be sheered. Remove the top shroud and flywheel nut, then while pulling upwards on the flywheel have someone strike downwards on the crankshaft with a hammer and brass drift. Do not use a steel drift as it will damage the crankshaft. Hope this helps, regards Phil.

Oooh boy, I know you bent the shaft, but why it is blowing oil out the carb, I don't know if I would even bother with the blade, you could go buy the same mower, then you would have some parts. Unless you just bumped it hard enough to throw oil around in there, it might settle down, but it is a long shot. I hit a stump once and bent the crank, it was lights out for that mower. Hope this helps.
