1980 mfg. Winpower 15/10 pto generator on Model TDM trailer. 540 pto. I bought this generator to use with a stick welder and wire welder when I built my corral. It worked fine for that and still does. The info. plate and decals are faded but this is what I can still read, 5 min. Event Rating 15 KVA, Continuous Rating 10 KVA. It has 1 240 volt & 1 duplex 120 volt outlet, a 50 amp main breaker & 150 volt gauge. Runs good and can be tested for your inspection.
