This assumes you will be using a Delco 10SI alternator and is already a 12 volt, negative ground system. Remove the regulator and generator. Keep track of where the BAT wire from the regulator goes. This is where you will connect the wire from the BAT terminal on the alternator. The GEN and F or FIELD wires to/from the generator and regulator will be completely removed. Tape them off if you wish. If your regulator has a L (lights) terminal, don't use this wire either. If this is your case, tie this wire to any hot battery connection - probably at the ammeter. Include all appropriate fuses. Otherwise, wire the alternator as described in the articles. Take BAT from the alternator (using heavy wire - AWG 10 if possible) and connect it to where your regulator BAT wire went. Connect pin 2 on to alternator to the BAT stud on the alternator. Connect alternator pin 1 to your ignition switch.. through the indicator light/diode/resistor - depending on how you wish to configure this exciter terminal. I didn't note if your tractor was a diesel - if it is, you can probably connect the alternator pin 1 wire directly to the ignition switch. I recommend wiring this through a 47 ohm, 2 watt resistor if you decide to eliminate the indicator light or diode - as a current limiter in case you develope a wire short or alternator problem As for pulley size, try to make the alternator pulley 1/3 the size of the drive pulley. If you can't find a pulley that small, do the best you can.
