REALLY small PTO generator
I've got a JD 4110 gear on order, and had a transfer switch installed when we added a garage, but no generator as yet. We lose power up on this Vermont hillside 4-5x a year, and have been without power the past 2 days, so my attention is on this problem!
My calculations show I'd need about 8KW peak if I was running everything in the house. When I laid out the transfer box, I was pretty careful to distribute the motors on different legs and different circuits, so I think that 8KW is very conservative -- obviously I don't need to run everything at once.
I'm wondering if anyone makes a PTO generator smaller than the 10k units JD sells (which seem to be the same as the much cheaper one in the Northern Tools catalog). Or is the 10K unit (which requires 24hp PTO to reach 10k) fine on the 4110 (17hp PTO) if I don't try to max out the wattage?

REALLY small PTO generator
Thanks to all for the followups!
Mark, how do you figure the math for the Deere being cheaper than the Northern? If that includes the Northern trailer, I was figuring on doing my own, since the Northern one is sized for a 60kw generator, and looks almost road-worthy with those tires! I was thinking of just getting a set of wheels and cutting a chunk of plywood...
Otherwise, it looks like $1000 from Northern or about 1700 from my JD dealer.

Tom, thanks for the extra cautions. The transfer box is pretty well balanced leg-to-leg and circuit to circuit, I was careful to get the motors and other big loads distributed evenly so we could be selective.
I'm lucky to have a pretty savvy wife (in fact, I could put commas between those words.  SHE was the one when we visited the dealer and were looking at upscale lawn tractors that said: "I want something with a bucket"!
So in the event she ends up hooking up the generator and hitting the transfer switches when I'm not here, she'll probably be more cautious than I would and just use what she really needs.
Judging from the feedback here, I now plan to go with the 10kw unit, and figure that at the PTO hp difference, 17/24x10kw will get me to about the 7500kw area, which would almost max out my transfer box, which was sized for everything running and allowing for simultaneous motor startup. So hopefully, I'm over-engineered here, but like I said, we're pretty cautious anyway.
Thanks again to everyone and to Dennis for such a great resource!
