3 Pt PTO generators
Brian It should be a fairly easy conversion, you'll need to install a jackshaft with pulleys, so you can get the correct input speed. You'll need to find out what speed the generator needs to run at so it puts out the correct voltage, if the engine was a direct coupler that may be 3450RPM input to the generator, so you'd have to put pulleys on to go from 540RPM(PTO) to 3450RPM(input/generator).
Hope this helps alittle. Jerry

If you're going to build a generator yourself, be sure not only of the speed the generator should run, but also of the DIRECTION it is supposed to run, or you may get a nasty surprise.........

3450 RPM? Um, according to my generator manual, they want it to run at 3600 RPM to give correct 60hz AC. That's direct coupled. 3450 must be metric?  Regardless, that's quite a gear-up job for pulleys. That's why most PTO generators use a gear box I'd guess.

The one problem with gas generators is maintenance. If you have long periods between power outages and dont run the generator periodically then you could have a problem with stale fuel and gummed up carburators which will render the generator useless when the power goes out. Make sure you periodically start and let the generator run and keep fresh gas on hand.

Ran into a problem with a belt type drive a fellow had put together. What had happened in order to hit the RPM needed for the generator he had geared it so he didn't need to run the tractor at full RPM but ran into a problem with the tractor as he had no reserve to carry the load. Another words he set it up below the govenor's working range. What happened is that with load he couldn't maintain the RPM's to run in the proper frequency.

Brian,
Your idea is definitely do-able. How well it works will depend upon your level of design and planning. Naturally the first thing you'll need is some sort of 3pt mounted platform. Next, ya gotta get that 540 RPM PTO up to the gen's rated speed. Chances are, you'll need approximately a 1 to 4 gearbox. NOT a 4 to 1! YA gotta increase speed not reduce. Your best bet may be to use a pully drive system rather than a gear. If for no other reason than cost. Otherwise, you'll spend just as much if not more than buying new.
Only MO.

I need to know how to hook up a 120 / 240 switch the switch is numbered ,but I dont know what colored wire goes where?

Jackie: It's good you asked the question, but it also wouldn't be very responsible to do 'how to' direction over the web. I'm assuming this is a switch in an ordinary house lighting circuit. There are some good wiring made simple books and maybe some sites on the web. However, there are a number of possible approved connection methods and an assumption contained in any directions is that the existing circuit is wired correctly.
In general, the connections to a standard residential light switch are two wires--one white and the other black. Many switches have two terminals and are not polarized so the terminals can be used interchangeably. The bare ground wire in standard AC line connects to a ground lug in the receptacle box but does not go to the switch.
Some switches may be polarized, in which case they should have different coloured terminal screws and the terminals are not interchangeable. Other switches may have a ground terminal that should be coloured green, in which case it must be connected to the bare wire in the AC line. Three-way switch and power through switch box wiring uses black and red wiring rather than white and black.
Anyway, a complete set of rules for connecting the set could become very long--especially if tests for a miswired circuit are carried out. One thing to know though is that in standard 120V wiring, the black wire usually is hot while the white is common or neutral. However, that colour rule is reversed in the standard connection for lighting switches.
