Iron Horse,
Thanks for the input. I was not clear with the way I stated the original question, I did not mean to swap positions of the current pulleys, but rather to put a somewhat larger one on the gearbox end and a smaller one on the rotor end. Of course all of this would be to overcome and compensate for the fact that I only have a single speed
PTO. Trying to get the benefit of a higher speed without having to buy a new tractor.
