John Deere 3-PT hitch generator

I have located a 25KW generator that is supposed to be 220V, single phase, 3-PT mounted and sold/made by John Deere. I have not seen it yet so don't have a model number or a physical description. Asking price is $1000. It is an older model but unused. I have a 2N Ford that I plan to mount it on in the event of a power failure. My power needs are about one half or less than the generators capacity. Is the price fair and is the Ford/J.D. match-up doable?

Thanks!
Scott

I am a new tractor owner and newly living the "country" life where power is - well sometimes isn't.

Can I run a generator of this type with Kubota BX2200 (22 h.p.) and if so where in the world do you find one of these??

Any help would be appreciated.

Thanks Ken

Scott: If the unit is functional, that's a very fair price. PTO generators in general are a good setup, as they don't require maintaining an extra engine for occasional use. Around here, (Northern NY), lots of farmers have them for emergency backups, as they can hook up whatever tractor is handy and be back up and running quickly. You'll probably want to hook up a transfer switch setup to your electrical system, so you can "plug and play" if the power goes out.

Your Ford has a Category "1" 3-point hitch. Be sure the generator is not set up for category "2" tractors. If it is, at the least, the pins will be too big to fit in the hitch holes on your "N". The generator will have a 1-3/8" PTO shaft, and the 'N will have a 1-1/8" shaft. Unless it has been changed over to a 1-3/8" shaft, you will need an adapter. You probably will have to use the "fragile" sleeve type adapter, as the other style that extends the PTO will probably extend the PTO too far back, and not leave enough room for the powershaft.

If it is in working order, and will fit your tractor, it will work just fine, powering a load within the tractor's horsepower abilities.

One other thing... your tractor is governed at 2200 RPM's, and develops it's maximum horsepower at that speed. To run the PTO at 540 RPM, to get the required 60 Hertz out of the generator, the tractor will have to be throttled down to just under 1500 RPM's. This will further limit the electrical load the outfit can power, but it should still be capable of putting out a cery usable amount of electricity. JUST BE SURE NOT TO JERK THE THROTTLE WIDE OPEN, or you're going to "fry" a bunch of your stuff!

I see used pto gen sets for about $7 or $800.00 (or less) every once in a while, (older ones on axles) that can be put on a tractor and checked out while you watch. Can you do that with this one???? I'd want to see it work with a "decent" load on it BEFORE i paid for it! If it works as it should, it's a fair price if you can use it.

I've had several portable gen sets over the years, but i like the pto gen set i have now, "best". I "know", that i will always have a tractor ready to go with out wondering if it will start or not, "unlike" a portable gen set that doesn't get used very often. I can run it with a small tractor for light power needs, or put a bigger tractor on it for more power if needed.

2 PTO hp per kw does work out right, BUT, also keep in mind for "extended" pto work, you should never use more than 80% of the available "max" hp. your tractor makes.

Hope this helps,

Robert

Unless you're on city water your well pump will probably be your biggest draw. Look on the motor tag and multiply amp rating by 3 to get start draw. If you have a submersible pump ask your well man for the info. Also remember that unless specially designed to do so most alternators don't prduce "clean" power so don't use a computer or other sensative device.

I have been told that a rule of thumb is 2 HP per KW. Your tractor may work OK for light loads. You can always use it as an excuse to get a second, bigger tractor.
Check the generator drive shaft - if it has a six spline coupler it was designed for a 540 PTO.
However if it has the 21 spline coupler it was designed for a 1000 RPM PTO. Deere made them both ways. The price sound reasonable or even on the low side.

It's PTO driven. Our emergency power requirements are far below the generators maximum output. I don't see us needing over a couple thousand. Just enough to keep the freezer from thawing and to cook dinner, run it a couple hours day until the power comes back on.

I am interested as to whether $1000 sounds reasonable and if anyone has any horror stories about PTO driven generators. I don't know anyone that has ever used one. The fellow who owned this one has died and his widow is selling it. Tomorrow, time allowing I'll go look at it.

Does it run off the PTO or does it have its own motor? I don't think your 2N will have enough PTO power to run a generator of that size. I would suggest you check more on how much power is needed to run the generator before making any moves.

The power requierment of the generator is dependent of the load of the generator. We have a PTO generator that is a 12,000/20,000 watt (that's 12,000 watt continuous and 20,000 watt surge) With a small load we can run it with a JD 40, but for a full load it is all that an Oliver 88 can handle.
