I have for sale a Pincor 4500 generator. It mounts on the front PTO of a John Deere 140, 318, 322, 332 or side mount on a 110 and others. Owners manual included. 110/220 single phase. I sold my 140 and 318 and was thinking about adding some gearing to run it off my 540 PTO but decided I don't have the time to mess.
worked well when I last ran it, but I don't have a tractor to demonstrate.
I woul conder trading for a 540 pto generator. If you have one we can talk.
