Almost all generators have AVR. Automatic Voltage Regulator. Dropping in RPM should not effect voltage. Freq yes, but that doesn't much matter. That's why I monitor Freq. Not because it matters, but it tells me more about my loading then voltage.

Howdy,
You have made a good deal.
Because of the size, you get a lot of benefits which you might not be aware of. The genhead is a 4-pole head. That means the assembly spins at 1800rpm (+-200) It is known as commercial quality. The rotating mass will smooth out any power load applied, such as a large motor start, and then simple running load. Just because you have more generator than tractor does not mean a bad thing. You would be surprised later down the road that after your hooked up and running, how little power you really need. Every now and then you might see a spike with something turning on, and then a moment later, the load is small.
It just takes some good common sense when running under generator power.
Make sure your generator connection is up to the task to feed your panel, and dis-connect from the utility.

Small changes in frequency are not an issue, but running something designed to run at 60 hz at a frequency of 50 Hz instead can damage some equipment, motors will run 20% slower (and possibly overheat)

I'm guessing 50 HZ for a 60 HZ motor might be stretching it. And I don't know much about motors. I know there are better and poorer designs and higher and lower qualities. I would have no issue at all with 55 HZ. Or 65 HZ. I would however want to know why I am not holding frequency.
Usually with my small sets, the governor of the motor is simply not able to keep the motor at speed. Just like blowing snow. Heavy conditions, you lose RPM.

Howdy,
The best thing you want is a nice clean 240 volts, 60Hz.
Equipment likes these parameters.
You need to review what your wiring gauge is. The full power outlet from the Dayton PTO generator has a dedicated circuit breaker on it. It looks to be a 125 amp breaker. For full output connector #2 AWG welding cable is recommended, and you have the Anderson power pole connectors.

Back when I was a kid, we installed lots of electric heat. We figured 10 Watts per SF. That is 24KW for your heat if it all runs at the same time.
