Every once in awhile I see PTO-driven generators on CL. Is there any possibility that one of those could be modified (take the PTO shaft off and install a pulley) to run off of one of my GT's? Has anyone done that???

  I've read that most PTO driven genny's brgs don't like side loading w/ a pulley.

Paul, you could use a jack shaft for the belt drive and side thrust, just couple the jack shaft inline to the gen. shaft. It would work just fine as long as you got the pulley ratio correct to make the gen. turn 540 rpm's.

Thanks... I'm kind of envisioning some kind of Rube Goldberg setup that would possibly go on the back of my Cub 123. It has the 90-degree drive on it for the tiller. I bet I could fashion SOMETHING to make it run 540 RPM and also eliminate side load on the generator shaft. I really appreciate the input.

with the one we use around the farm you would need more hp to run it, but that also depends on what you run with it.

You can also buy conventional 2 pole 2 bearing generator heads from Northern Tool and probably other places. They run at 3600 so are a better match to the typical GT PTO. Getting a 3600rpm PTO back down to 540 is a big ratio to do in one set of pulleys. Considering the power you need to transmit the driving pulley would need to be a good size which would make a 6:1 + reduction impractical because of driven pulley size.

I have several original GT powered generators. I last used one 29 years ago. I keep them for plan "C" options. Plan "A" is just a regular stand alone generator. They come up on CL often for cheap. There was an 8kw on CL for $200 last week. It ran but stopped making power. This is usually easily fixed (fuse or energizing) but I didn't have room for it. The attachment generators usually are more expensive than the stand alone. I'd rather not put the hours on a tractor. Good Luck, Rick
