What kind of RPM are you shooting for? What would recommended be?
I've been thinking about building something like this. Might go with swinging blades for a disc mower instead of string.
You don't need a shear bolt on belt driven mowers. Finish mowers don't have one. They depend on belt slip.
I'm not sure but will guess you mean this type of swinging mowing blades. But I agree, that stings do not need a shear pin.
I don't think anyone was suggesting a shear pin for the driveline. I was asking about something in the frame that would give way before something bent...in the event of daydreaming while driving through a gate, garage door, past a tree, clothesline, wife's brand new car, etc.
