Im sorry Mike, but for your PTO I meant a generator (I call them alternators). It may sound like a costly way to go, but someday you may want to power something bigger, or run your house, and then you will not have enough power. An air compressor, for example, needs about 10 KW to start. As far as the alternator is concerned, I suggest rewiring it to produce three phase. To do that, you need to pull apart the alternator (Ford alternators work the best for this)and remove the diodes, and the regulator. The wires going to the diodes are then routed outside, and become your HOT wires. The stator terminal on the back of the alternator becomes the Y common. In order to produce maximum power, you must measure the voltage on the field as it charges a battery, and then build a feedback circuit that will energize the field without burning up the alternator. A setup like this could produce 70 volts approximately, so you would need to buy a step up transformer. They are faily cheap (Square D, or Cuttler Hammer) and double the voltage. That is the only drawback, but it should produce 600- 1200 watts. You may not like this system, but I find it quite useful for the three phase it produces.
