[AT] Allis D10s/D12s

[charlie hill]

Cecil,  the Series III DOES have live PTO. Or at least if it doesn't I am
badly fooled.  I'm not sure exactly how it works.  I've never dug into one
and haven't even looked at one up close in several years.

Ah,  I just looked in Swinford's book.  The later model ('62 and up) 10's
and 12's had a seperate PTO shaft run directly from the engine flywheel
through a hollow transmission input shaft.  He didn't explain how the PTO is
clutched but did state that they were all independant PTO.
