Not sure what is under the rear end of my e-12m, but I see the same as
Larry's e-12 when I throw the e-12m in reverse while still moving
forward (noting bad).
In fact I used that method while pulling the 16 ft trailer on the
hayride.  I was rolling down a hill forward and used the reverse to stop
the forward motion.  I think it isn't the best for the unit but when you
have to stop and it is the only option for me, I had to use it.  That is
what I love about my e-12m after reading all the post over the years of
the e-15 smoke while doing the same operation.  

Man I need to find time to upgrade the brakes.....

     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 ?
