what happens when the tractor's pto hp is lower than the hp needed to power a generator to its full output? I have only 10 pto hp but want to buy a 7.5 kw generator. I know I cant power it to the top end but I should be able to use 5 or 6 kw right? I'm assuming the motor would stall if I try to power too many loads at once. Would a short surge of a bigger motor like a well pump coming on just kinda make the motor struggle momentarily or what? I just need some back up hot water and water pressure and a few lights and of course a tv. Not necessarily all loads at once. I'd rather not buy another motor to maintain if i can get away with it.

You need 14 HP to run that generator to full output, or approximately 2HP per KW.
At 10 HP PTO output, you can get about 5.1 KW, enough to power the things you mention.
Actually, starting a motor will be easier with the lower HP than if you were at full 14HP. So the water pump should be no problem.
You would be able to keep some lights on, watch tv, keep the fridge running and more.

I just gotta put in my 2 cents.
I thought for a long time that I wanted a PTO generator, then I thought about when we lose power: Winter, usually with wind and rain. Do I want to be out there wrestleing with a 3 pt. hitch to hook up a generator in the dark, in the wind & rain? And if there is snow, do I want to unhook the generator, then hook up my blade so I can clear the driveway, then hook up the generator again? Not really.
So I got a Briggs powered generator which sits in the garage, next to the panel. I get it all hooked up, ready to go, then open the door, roll it outside & hit the starter switch (electric start), step back inside & start flipping breakers on my transfer panel.
These generators are sold all over the place, which means you can get them on sale for a price that is close to the pto models.
Think about it.

Two comments:
I have used a 7.5 kW PTO generator on 12hp tractor just fine as long as I kept the load to the 5-6 kW range.
There is a substantial difference in the noise level between a well muffled tractor running at rated speed and one of the portable gasoline driven generators running at 3600 rpm. This from experience at dog shows where a lot of RV are in use. Those that have built in generators are well muffled are hardly noticed; those that use the portables are asked to park at the far end of the lot.

I know what you mean Pilot, and I am mulling it over. I can't seem to shake the idea of no motor though. Right now I have 4 cars, 1 tractor, 1 hydro walk behind, 1 trim mower, a snowblower, weed eaters, a chain saw that all need some kind of maintainance. Throw in the inlaw's 5 cars, 2 mowers, snowblower, the parent's 2 cars, mowers, tractor, snowblower,and you can see why anything that has no motor gets my attention.

Good point about all the equipment that needs maintenance.
And texbaylea is right about the noise. I understand that Honda engines are quieter, but haven't tried one. There is a muffler available for Briggs engines, but it is not cheap. In my case, the generator parks outside the garage, which is between the house and the noise, so it is loud enough to hear, but not loud enough to be annoying. But wear ear protection when starting or stopping the machine.
Fuel is another concern. If it gets cold where you are, you need to make sure you can start your tractor when it is cold. And if you go with the gas powered units, my Briggs engine says not to use gas with ethanol, which in our case means to stock up before the winter ethanol requirement goes into effect.

I would have to disagree. I have a standard gas genny right now that is 3 years old and is a major P.O.S. ! although it only has a few hours on it. I have to continually maintain the this thing in the summer even though my tractor is always in running order.
I would much rather just unhook my snowblower from the tractor and hook up a PTO Genny. Especially when i am at work. All the wife has to do is turn the key on the tractor and she is good to go.
The life span of a gas genny does not seem to be anywhere close to a pto genny either. Even though the price per KW sure is compareable. Go figure.

I have a couple 6kw gas gens, one being a back-up if one fails. Fortunately we dont have the problem of having to unhook to put on snowblower here. I am considering a pto genset since i have a smaller tractor to run a 15kw. Fuel management is a consideration (deisel vs gas) I wouldnt know for sure but have been told deisel has a longer shelf life than gas. The gen is only used here for a few days at a time after power outages after severe hurricane passage. The longest i have been out of power was 7 days straight and i consider myself lucky. I just built a new home (not in yet) and i will have it wired so as to disconnect from pwr company service and plug in gen power. My current intent is to manage power needs thru panel as noted above. In the past we havent run it 24/7 but for necessities such as food prep, showers and water for cattle until late evening when temps cooled enough to sleep. Yep, probably will get a pto genset.

Until last fall, I was the proud owner of a Miller Bobcat Welder with an 8KW generator on board. It got used just enough as a welder to keep it running during the months that I didn't need the generator. Ocassionally it would give me a little trouble from lack of use, as does any gas engine, but never anything more than a battery or one time a fuel problem. It gave dual useage so didn't sit nearly as much. I would hook it up during the hottest months and run the a/c to cool the house down to about 64 as a treat to my wife, who hates a hot house. Figured I needed to run it anyway, so why not make her happy to boot.
For the homes with a gas driven generator, fire it up and run the house at least twice a month. Keep the fuel topped off and run it long enough to use enough fuel to have changed the tank every couple of months.

That's where I favor the tractor... what's got a better chance to start? The 200$ brigs engine that gets run 5 minutes a year to check on it, or the 6000$ tractor engine that may get run weekly or daily, and is in all likelyhood, just a better and more robustly designed engine..
