I just found and fixed up a 1978, F-motor Lawnboy. This is nostalgic for me because that was the exact (as best I can remember) mower my dad owned when I was growing up; the first mower I personally used.
Thinking back, I must have been extremely young when I first mowed with it. (We had to be careful to buy UL gas “special” for the mower…as opposed to the TEL that went in the BMW Bavaria, so I’m guessing around 1980, give or take.) That would have made me–EGAD!–8 y.o., which would probably get CYS called today. (In fairness to my dad, I was a “gear head” in a big hurry to prove how “adult” I was, so I suspect I about held him hostage and demanded to mow.)
So, how old were you when you got to use the power tools? How old do you want your children/nephews/etc to be?
For me, I think I could trust a 15 y.o. to mow the lawn, but only after close supervision-then I’d let him use the line trimmer a half-dozen times and see if he handles that acceptably–appropriate footwear, eye protection at all times, etc. If he passes that test, then okay. I don’t think I’d let anyone <18 do second-story ladder work, however. I don’t under ANY circumstances, allow ANYONE of ANY age to come near my table saw or my hand-held cutting wheel…and I tremble a bit even when I use them!
(P.S. I used the mower, uneventfully, throughout my childhood. Eventually, familiarity bred contempt, and I broke my middle finger clearing a jam on my mower…at the age of 40. Lesson learned there!)
