===========================
Good points you brought up, Chris.

I have repaired several GE lift motors myself, and had several that were 
not 
repairable. I have now sold all my GE tractors, but still have a New Idea 
that 
I use. Most of you probably know that the New Idea lift motor is 
completely 
different from those on the GE's - it is not a window lift motor, but 
appears 
to be a heavier duty motor designed for this use. I have never had 
occasion to 
work on this motor, as it has never failed. I also heard on this newsgroup 
that some of the NI lift motors were actually rated at 36 volts, rather 
than 12 
volt/used on 18 like mine is.

Since the NI tractors were actually built by GE, (as I understand) how 
does 
it happen that the lift motor is different? Did New Idea demand a better 
motor, 
or did the later GE's also have this better motor?

Would someone out there with more knowledge than me enlighten us on this ?
