OOPS.  Yes, E12 (NOT S) E12 26AE12HA GR17 963.  Same control as E12M.  The 
S has the electronic controls.

I stand corrected.  Yep, THAT'S why it's robust.

     Is it within the realm of possibility that there exists some 
confusion 
between the E-12 S, which has a front mount mower and electronic controls, 
the E-12, which also has a front mount mower, but has a centrifugal switch 
on the traction motor, traction  motor reversal handled by contactors and 
the E-12 M, that has the same electrical configuration as the E-12, but 
has 
a mid mount mower ?
