The math isn't correct. At the high pto speed the engine is running 1531 rpm.
I would not hesitate to run at this speed providing you limited the load to essential items, perhaps during night time to provide power for heat (not electric) lights, fridge & freezer.
During power outages fuel can be limited so being efficient by using the higher pto speed can be the difference between staying warm or freezing.
If more KW are needed during the day change to 540 rpm for full power.
Some have said they don't want to put the hours on their tractor, hello what did you buy it for?
A quality well maintained tractor will provide many thousands of hours of use. The time spent running a generator will not impact the life of your tractor providing you do not overload it.
Another point to consider is the tractor is always ready to run and for extended lengths of time.
Be aware that it takes hp to just spin the generator up to speed and energize it and this power requirement increases as the KW rating of the generator increases. This is before any load is applied.
I have a Generac pto 25kw generator with a surge of 50kw that I run with my ford 1720 23 pto hp. As I start to spin it up it free wheels until it energizes and then it puts a noticeable load on the engine, not much but noticeable.
When I bought it I did a load test and operated the entire house for 8 hours to test fuel consumption.
We have a deep well pump and my wife did laundry & used the dryer rated at 5500 watts along with TV & all the lights and it used 5 gallons in 8 hours.
Hope this helps.
