If you figured things correctly, along matched power to current demands - yes - you could adapt a 1000 RPM PTO to a 545 RPM generator and run the engine at a lower speed. But, that probably puts the tractor out of it's peak torque and efficiency curve.
It takes around 1 horse to make 500 watts of power. I've got a 15KW PTO rig I've hooked many times to my 32 horse IH tractor and it did fine. Also ran it on my little VAC Case. Can't say I ever used it at full capacity though. Ran my entire house on it, ran a 200 amp welder, etc. No problems.
A large PTO generator is never going to be efficient unless your're working the tractor in it's peak range. That's the curse of making your own power. Usally electric demands are intermittent so overall efficiency is low. A 3000 watt generator with a 5 horse gas engine will run a lot more efficiently at 3000 watts than a 30-50 horse diesel tractor hooked to a PTO generator - if only making 3000 watts.
The only way to get top efficiency when the demand is not steady is to use a battery bank and inverter. Run the bank until it gets low, then charge it up with a diesel generator sized properly to run at full efficiency to recharge the bank - and then shut down.
Another option - is to use a tractor hooked to a PTO DC generator and then through a large inverter. This way, you can run the tractor at any RPM and still get 60 cycle current.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
