Re: (ET) current ratings for contactors? 50A enough for PTO?

Probably because it has to dump extra energy when going open and effectively shorting out the mower deck motors. That's a lot of energy stopping very quickly.
100a is about right for blowing snow. I don't have a shunt on that line specifically, but 300+ amps would include the drive motor shoving the thing up hill.

  They were Prestolite contactors. I have the spec. sheet. The Normally 
Open contacts are rated at 100 amps and the Normally Closed at 150 amps.
  Doesn't seem right that the NO are lower than NC but the NC are Silver 
and the NO copper.

I just wish I could find some kind of GE document or other resource that
actually stated the current rating of these contactors.
