Very often Ty,
On American mowers the blade boss is small and when the blade hits something it is more likely to bend the crank than the blade...
one blade costs anywhere from $5 to $25 it all depends on the mower and blade(s) that need replacing...
Infact, IMO The blade disc seems like a better idea, after dirty carby's bent cranks are the most common reason for mowers being thrown out...
