The mower is 4 yrs only.6.5 hp. This is the second time I hit something next to it. Last time it was a moment ago the key. This time we already replaced the knob. I hit pretty hard, the cessation of the blade bent 90 degreees. The engine sputters for a second, then nil. What else could be wrong?
This sounds like you may hold bent the shaft. First remove the spark plug for safety, and to get rid of compression in the engine. From the bottom side of the mower deck, manoeuvre the distance from the blade to the deck. Now measure the differing end of the blade. They should be matching. Try this in several different locations.
If you can get it up within the air (on a rack) or lately tilt the handle fund to the ground to raise the front closing up with the plug and blade removed, you can verbs the rope while someone looks to see if the shaft is bent. It'll be easy to inform if it's not perfectly straight while it's spinning.
The problem is that a mower next to a bent shaft will still run if that's all that's wrong near it (although it will vibrate excessively). You could hold knocked the coil perforation out when you replaced the key. All it take to fix that is a business card between the flywheel and coil. This will ensure the correct distance when you tighten down the coil.
Answers: Cranks are the toughest part of any engine. The worst or conceivably the best I've seen be a V-12 Jaguar crank when it locked up in a see. In your case I've never see anyone hit a stump with ample gusto to bend a blade 90%. If I was to guess, I conjecture all you may enjoy done is trashed the internal govenor. RScott
