Re: (ET) Curtis controller mod

So ideally the field weakening should only be used occasionally, not when 
doing active things (mowing, etc.).

My understanding, and i think it is stated in the manual, is that field 
weakening is only to be used occasionally when torque is not required 
(working) as a short burst of speed. As weakening the field causes the 
motor to spin faster, use more power, loose torque, and generate more 
heat. It does say that "whenever possible the speed control should be 
maintained in the recommended DRIVE position for most efficient 
operation". Drive position is straight 36v, non weakened field. 

It is a extra feature, not something intended to be used as a normal 
operating mode.
