[AT] Farmall Super M, Stage II, question down in the weeds

[Dean Vinson]

Hi gang.  I've noticed something on my recently-acquired late Super M that I
can't quite figure out.  Cast into the left side of the chassis, right above
where the Lift-All ports would have been on an M or early Super M, there are
three small flat vertical faces, each one drilled and tapped for a machine
screw.  I assume they're mounting bosses for some type of attachment, but
can't figure out what it might have been.  Any of you folks know?

This evening at the Miami Valley Steam Threshers show in Plain City, Ohio, I
checked out several other Super Ms.  The Stage I Super Ms, from both Farmall
Works and Louisville, didn't have the mounting bosses.  The Stage IIs, from
both Farmall Works and Louisville, did have them, although they weren't
drilled and tapped like they are on my tractor.  Here's a photo of one of
the tractors from the show:

Anyway, I'm curious what they were used for.  There are no comparable
mounting points on the right side of the tractor.  The belt pulley drive is
on the right side of the tractor at about that same relative location, so I
thought maybe they were used to help secure something that attaches to the
pulley drive, like the Electrall generators.  But the Electralls didn't come
out until later, and the Super MTAs and 400s don't have these mounting
bosses. 

Anybody know the story?

Thanks much.
