"Learn from the mistakes of others, you can't live long enough to make them all yourself."
Roosevelt, Eleanor
There are numerous "safety pointers" that pop up peculiar to tractors and general TBN life.

Often the directions or warnings are in the manual IF you have it, but not explained.

My example is
remove seat before disconnecting backhoe.

Because IF YOU DON'T, when you are trying to "jiggle" the backhoe off the pins with the hydraulics the seat can flip forward and knock the levers folding the stabilizers and the hoe in, causing the operators station to rise like a rocket. While you grab to pull the hydraulics back. And the tractor get's picked up. Not specifically spelled out in the manual, but can require a change of underwear.

Or so I've been told.

Or on another thread about checking the 3pt position before you drop the implement on your foot.

I'm thinking it would be good to have a moderated thread primarily limited to links to "I did this and WHOOPS, this happened" elsewhere on TBN.
