I wouldn't worry about the lawnmower man, just tighten the blades to 40ft/lb
indicated ( assuming that's the right spec) on the wrench and you will be
fine. With an 18 inch wrench even a 90 pound weakling :-) should be able to
get 40 ft/lb.

I personally would just tighten them till they are tight without using a
torque wrench but until you determine what tight means just trust the
wrench.

Just picked up my newly sharpened blades from the mower place. The repair
guys said "Make damn sure you tighten the bolts right. There's no way to
get the required 40 ft/lb torque with a 3/8" drive. With a breaker bar,
yes, but not with a 3/8 torque wrench." I have a 3/8" drive Matco torque
wrench with adjustments from 10 to 100 ft lbs. It's 18" long, bigger than
any breaker bar I have.

What's this repair guy talking about?
