I have a friend who used a B7500 on a 15KW genset. We would put the PTO in 1000RPM and run the tractor just off an idle. The tractor had a tendency to try to overheat so we put a regular 110V box fan in front of the radiator to keep up the air flow. It worked pretty well and was efficient on fuel. However I did not care for the idea because the cost per hour to operate a tractor is significantly higher than a stand alone generator. I have a stand alone 9 KW honda powered genset, it replaced a Tecumseh 7 KW unit that I wore out. I am at the end of the line and have gone over 10 days without power. It is common to spend 5+ days a year powerless, I would hate to put those sort of hours on a tractor. I just spent 2K to rebuild the engine on the Massey, I can buy 2 Honda powered gensets for that cost. When we are running the generator I put synthetic oil in it and give it an oil change every 48 hours to try to get more life out of it. If I need power in the field I put the genset in the loader bucket and carry it with me.
Another example of these 1/2 throttle on a 1000rpm tractor connected to a 540rpm generator is not a good idea. The advocated to such abhorrent behaviours never calculated the actual costs using accurate facts.
For reasons unknown some people think 1/2 throttle = 1/2 the fuel used ???
