Building a PTO generator

[Soundguy]

I see someone beat me to the punch on the chain drive / sprockets / carrier bearing idea...

http://surpluscenter.com they have surplus gen heads and all types of bearings,pto shafts and belt pulleys.
Also the exact rpm wont matter to much,most 60 cycle appliances work perfectly well on anywhere from50 to 70 cycle power.

I am thinking of a different route here. I have a flail mower that I re-built recently and it gave me the idea. The gearbox ( big) has a PTO shaft input, 4:1 reduction and a right angle drive output shaft with basically no side load on it that I think I could just Lovejoy couple to a generator. Also, the right angle positioning might allow me to see the meter on the side of the generator.
Unfortunately, I thought of all this after I did a nice job re-building the mower so I am looking for another gearbox /forums/images/graemlins/frown.gif
This is a little different home built approach, but it seems more like what the pro units have, anybody's thoughts are welcome.

Read my post, want to be technically correct - the gearbox has a 1:4 ratio, so it is technically not a reduction /forums/images/graemlins/tongue.gif
Bottom line is it would be a decent match for an 1800 rpm generator head without running the tractor hard.
