I buy a tractor two years ago, and four-fifths of the tractor manual is about not tipping over, not raising the bucket high enough to hit high-tension wire... not killing yourself, basically. And in that manual, I found out - and it cost me a thousand dollars - that when the tractor is new, 10 hours into use of the tractor, you have to re-torque the lug nuts. If you don't, you will oval the holes. This is buried between the moron warnings. I never found it. I take the tractor in for its regular servicing, and they say my wheels are gone. How am I supposed to know that? "It's in the manual." - P. J. O'Rourke
