pto backup generator

3600rpm two pole pto generators tend to be screamers .

I have a 12KW Baumalight trailer mount generator I've been using for 10 years now. For weather protection, I leave the generator in the barn with the tractor outside and close the overhead door so it just clears the driveshaft. Although the trailer mount takes up a bit more floor space, I find it quicker and easier to hook up than a 3pt mount.

I used to have a 8kw gas portable but getting up in the middle of the night to fuel it was a pain. Looked at the pto he set but finally settled on a Koehler 12kw fueled by propane. Our fuel supplier got tired of servicing the pigs and made me a deal. If I would dig a hole they would give me a 500 gallon tank. Works great and supplies my shop heater, space heater in my inlaw apt, stove in main house, and the generator. As noted in a previous note having your own well is great but you need a constant supply of power to get any water.

15000 watts divided by 746 watts per Horsepower is around 20 HP at the pto to run the gen set, would this be correct? Or do you need a little more for spikes in load? Just wondering what the rating are on those as the little tractor I have only has 21 or 22 pto HP if I remember correctly.

Your math assumes 100% efficiency which no generator is capable of producing. Allowing for losses, 21 pto hp is adequate for a 12 kw generator at 100% load. Of course you can use a larger generator but 21 hp will not allow 100% output. If you put too much load on an under powered generator, you run the risk of voltage drop which can damage electrical equipment.

I heard you should figure 2hp per kw....is that still a good figure?

I'd be concerned about getting a consistent 60Hz cycle out of a pto generator powering circuits in a house due to varying load, since the tractor throttle isn't governed.

A tractors throttle IS governed! Set the throttle under an average load and the tractors governor takes care of the spikes...

2hp per 1,000 watts will keep everything cool and allows for a long service life...

Tractors have been governed since the steam powered tractors.

Here is one powering a saw mill. Hear it pull hard when it starts cutting wood.

Good to know!

Ya. How else do they hold 540rpm or any consistent speed? You set it to the appropriate engine RPM with the hand throttle & go. It holds it until you surpass max torque the engine can generate, then it starts lugging.

I don't really notice the noise over the 45hp Yanmar Direct Injection engine at 2500rpm.

If you have the time to assemble your own PTO generator and carrier from parts, consider the folks at Central Georgia Generator and check out the rigs their customers have built:

I don't really notice it on my tractor with the pto at 540, at 2,000...

It's really no big deal, I can't even hear the tractor/generator running when I'm in the house...

For maintenance, my genset manual says, "change the armature bearings every 80,000 hours"...yes, eighty thousand!

I don't think I'll be running it 9 plus YEARS of continuous running over MY life time!!

Yeah Seriously, I've had mine over a year and only put 25 hours on it -- Most of them after the huge windstorm that knocked out power throughout the northeast last October. It sure came in handy tho! I ran it four days, about 5 hours per day, as needed to run the well pump and appliances.

2HP per Kw gives margin for motor starting and allows operation of the engine at less than full rated load . Fuel efficiency will suffer however with a 40HP engine driving a 20KW load vs a 30HP engine driving a 20KW load.

I just recently setup a generator for the house.

Wanted easiest setup for wife or anyone I needed to set it up when I am out of town.

It’s a champion power equipment model 100110 ( 9,200 running watts, 11,500 max watts). I have a interlock switch to prevent the main breaker and generator breaker from being able to be on at the same time.

I am currently keeping 28 gallons of fuel on hand with a full tank ( 7.7 gallons) in the portable generator. It is said to get 10 hours at 50% load on the 7.7 gallons. So I got just under 5 full tanks/ 50 hours of fuel available. I am looking into a 55 gallon drum to store more fuel.

Overall, it’s simple to setup and get on line, runs all but my stove, oven m, dryer and AC. I can run some of the stove but not all.

I don’t want to loose wattage output by converting to LP or NG. Happy with the setup overall. $3,500 at most invested.

And by cycling it, the fuel will last a lot longer. Your freezer will go over a day without power, the fridge about 5 hours. During a long outage, we take showers when the generator is running as we are on a well. Typically run it an hour every 5-6 hours. So 5 hours a day. Doing that your current fuel supply will last 7- 10 days. Ethanol free gas will last longer but is 35% more costly, so we use 10% ethanol with Seafoam added, but we only keep it for a year, then use it in the vehicles.

If you go with a 55 gallon drum, it needs to be vented. We have a 300 gallon tank with a hose and fill nozzle to make dispensing safe and easy. Our codes here call for it to be 50’ from a building. Before getting the tank, I had 10 5 gallon plastic gas cans stored in the garage but was always worried about how the insurance company would view that if I had a fire. The tank is safer and is handy for fueling the snowmobiles, lawn tractor and the other stuff we have.

I can get ethanol free also, but plan to do 10% or less. I am treating with PRI-G fuel treatment. Have seen videos and reviews that say it’s amazing.

Unless I know we are gonna be our for a really long time, we will probably keep it running most of the time for tv and all the other conveniences.

As for hooking it up, just back the tractor up to it, hook the pto shaft and start the pto..

Not too big a deal as far as I'm concerned, especially when you consider the money saved....

But, you do have to be there to do that.

We travel a lot. And, I would not expect my wife to do that while I'm at work. She can drive/operate the tractor, but I can't see her hooking up a 3pt implement. Especially if the backhoe happens to be on and needs to be detached first...

For me, a propane powered stand-by is well worth the money spent. The fuel never goes bad, there is always ample amount of fuel on hand, and the exercise cycle means that all systems are tested on a weekly basis.
