I'm not quite sure if I'm right but I thought I should mention this. Let's assume that you take a 20 hp motor with for example 2000 rpm maximum speed (I don't know the specs for your Farmall) and you are using gears or whatever in order to get the final rpm to the required 3600. Will the power in the end of the 3600 rpm shaft be that same 20 hp? I don't think so. What you gain in speed, you lose it in power. So you would have to use more powerful motor than the 20 hp. Again I have no idea about your tractors hp so it might be powerful enough for your purposes. But you should consider this.

Also, as the other reply said, it's critical to keep the speed of the engine constant so the voltage remains steady and even more importantly, the frequency of the current is kept constant. There should be some sort of device that is connected to the throttle of the tractor and alters its position according to the power needed by the generator (or is it called alternator?).
