3-Point Hitch John Deere 3-point hitch 10 KW PTO Generator

Here's some math:

One HP = 746 watts. That would mean that if you want to run 10KW:

10,000/746 = ~13.5 HP. You also have to figure efficiency because alternators aren't 100% efficient. It's best to figure about 75% efficiency so that would equate to:

746 x .75 = 560; 10,000 / 560 = ~17.85 PTO hp give or take.

I would not under power the generator (It's really an alternator by the way) because it could cause equipment problems and over heated motors. I would run the gen. to circuit breakers to protect it.

One more thing. While most of the new stuff coming out is brushless make sure the one you want is too. Also copper wire is rated for heat. That is you can get 150C (Celsius) or 200C for example. What that means is that the wire itself is capable of running at that temperature or near it. The higher the number the greater ability to withstand heat.

How did you size your generator?? I am looking at the Generac 17kw but am not sure if it is overkill. I have a 1000 gal lp tank.

I have a well, Geo-thermal heat, electric water heater, and electric stove. I think they would require more capacity than normal houses.

Generac Generac Power Systems - Residential generators and Kohler and others have some good online info including calculators to determine the size generator you will need and it all depends on what you want for emergency power in your home. I'd start off with bare essentials and see what minimal size generator is required. You can then add items for "nice to have" and see what maximum size is needed. This is easy to do with the online size calculators available at each manufacturer website. I think if I had it to do over I'd go with the whole house automatic transfer switch and go slightly bigger on the generator. I see Generac now has a 17 kw air cooled unit available with 200 amp transfer switch. This would have been a better solution for me but it was not available a few years ago. Like KennyD says, once you get into liquid cooled generators the prices spike up. I have a 500 gal LP tank but the generator is the only load on it. I think I calculated it would run the generator 24/7 for 20 some days at nominal power load. Having a 1000 gal LP tank, you are probably good for fuel depending on what else you have connected and how low you let the tank go prior to refilling.

Also, you can save a lot of money by shopping around on the internet after you determine which unit you want. Just search on standby generators.

Yeah, that new 17kw with the 200 amp TS is the cat's meow...plus it has an aluminum enclosure that will not rust like my 15kw is

I bought mine and a 7kw Generac from Norwall Power Systems. I highly recommend them.

Sunnyside,
I know you're running it for 20 days but that seems like a big fuel expense. Upstate NY the LPG rates are very high.

The 20 days is a conservative estimate. You can only fill an LP tank 80% full which is 400 gal in 500 gal tank. Just had my tank topped off last month at $1.19 per gal which isn't too bad. What are you paying in NY?
The longest time power has been off the past 10 yrs was 4 days during a big ice storm.

He He I would not call 20 gals a day conservative, what would you guys do in a civil war?


Just kidding you.

We only use LPG for cooking here and I just had my local dealer fill the tank. Residential LPG is $3.42 a gallon.
We lose power, I'd say, at least 4 to 5 times a year but we're right on the end of the line in a rural area so the folks closer to the village are probably less prone to a failure rate this high.
My solar will switch over automatically but I haven't done the math yet to see how long it will run without sun or wind. I'm still doing appliance evaluations with a P3.
Anyway it's not a bad idea to get a P3 (killawatt meter). They run about 25 bucks and you can move one from appliance to appliance over a several month period to get a good idea of what your power consumption is. This way you can size your gen set without guessing what you'll need.
Most of my neighbors have small diesel plants that switch over when the mains is down. They aren't that quiet though and I don't know how they sleep with it running.
Solar is great but it costs a lot and you have to know what you're doing. I'm an EE and I still had to call Outback to get information setting up their inverters, AC and DC power panels.
My goal is to run everything and some heating depending on how my stream does. Solar today is pretty neat stuff and dependable.

$3.42/gal - WOW! I get mine a little cheaper because I own the tank but $3.42 is off the chart. The small kilowatt meter is a good idea to get a feel for power drain on your system. Motors starting up add some but you can take a swag at that.
This morning I took a look at my electric bills for the past year and they avg about 600 kwhr per month which is 20 kwhrs per day. Comparing this to the generator running at half load (7.5 kw) for 30 days results in 5400 kwhrs so my 20 day run time estimate for a tank of LP gas (400 gal) is way way low. The Generac operator/owner manual only specifies fuel usage for half and full generator load. I've never really measured fuel consumption but thinking I will.
The solar and wind power systems seem like a good way to go but I've never checked it out.

What are they quoting for the 10 KW Deere PTO Generator. I have been looking at the Northern Tool 7.2 kw and 13 kw. $829 & $1300 respectively.

Plus add cost of drive shaft assembly.

Don't plan on mounting it solid on a concrete foundation. Remember it needs to be movable.

SPENCE

I paid $2300 for the Generator, Shaft and of course taxes..

I just have to wonder, how am I supposed to keep my wife outside in a hurricane on the seat of the tractor to keep my beer cold??

Is there an authorized and safe way to bypass the seat switch?

What tractor Bob? They are all different. My 4110 you just pull UP the seat switch, but the newer machines are different. The owners manual also tells you how...
