Shear maddness (from winching)

Folks,

I have greatly enjoyed the many helpfull comments
about winching and would like to add a bit on why not
bolts...

I have a winch on my M211 that I'm guessing a previous
owner left the PTO and the winch clutch engaged and
tried to drive off. I truly wish that a shear pin
would have given out but I'm guessing that there must
have been a bolt involved because the clutch dog kind
of exploded. being the resourceful types that they
were, they used a considerable amount of rod and
welded the winch drum straight to the shaft. After
all, that clutch thing is a pain anyway right?

I learned the same kind of lesson with a snow blower
personally after my field expedient bolt go painted
and forgotten. I wedged a rock and a shear pin let go
and all was well except that the shear pin that let go
was inside the center gear housing requiring a
complete tear down of the auger assembly.

Get the right pin, and a bunch of extras, and do it
right.
