I've never seen a shear protection device on a lawn mower
blade. God help you.

I have had a couple cheap mowers that the blades were driven by steel
rivets with the head in a dimple in the drive hub

Actually...neither have I. Nor have I seen a bent crank in any decent
quality lawn mower motor.

Last fall Junior dragged a rear bagger home and I used to pick up all
the 20+ bags of leaves after I got the run out down from 0.1 to less
than 0.01" by judicious repeated application of a 4 pound hammer

Precision work requires the right tool for the job. You couldn't
do that with a bigger hammer.
