Question about Mtd 22" Yard Machine Push Mower
Hi and welcome to FixYa, I am Kelly
Hitting a stump did not do your mower any favors. The most common thing that fails when the blade is suddenly stopped is the flywheel Key. The keys are aluminum and made to shear so that the crank shaft is normally not twisted off at the point where the flywheel itself is bolted to the crankshaft.
The very thing you will have to do is remove the flywheel and inspect the key and keyways on the crank shaft and the flywheel. It will take a puller to remove the flywheel. Most flywheels have at least 2 holes in them where you can install bolts to assist in pullig the flywheel. The bolts must be threaded all the way in to the stopping point or they will ruin the flywheel. You MUST clean the holes out first before installing the bolts because they usually clog with lawn cutting debris.
Here is the bad news... If the flywheel key did not fail quick enough the resulting dmage can be the crankshaft gets twisted or the connecting rod can bend.
I need a complete engine type model and serial number (B&S) or just the engine number for a Honda engine to pass on any more applicable information. If you respond with that information I can help you with parts sources and probably a service manual for your engine to assist you in sorting out the damage.
Thanks for Choosing FixYa,
