Oops - should have said max RPM not max speed.

big it was when I looked underneath the chassis. The ran a deck motor today
at 12V and was surprised at the torque - also more than I thought.

It's strange that there seems to be no 'official' GE data sheet on the 
motor
itself. But I guess if it was special built for Elec-trak there was no 
need.
Also I guess if they listed it as 5HP all the gas engine guys would scoff.

computed the continuous HP, my E12 is 4 or 5 HP.  The deck motors compute

about 1 HP by the same method.
