Re: (ET) first mow



If I am not full field (as I suspect), would that have a large effect on
motor power? I've been reading up on electric motors (I dodged the electic
motor class in college - "I want to build computers, not motors!" - now 
it's
payback time) and am trying to better understand how these things work.
