PTO Generators, been here before?

like I said.....'Things must be different in Norway'.....

5030,

Every tractor I've seen has a governor, and I'm not in Norway. Do your tractors work like a car going up a hill and you push the clutch in, and the rpms go sky high? I doubt it. If they do they're not working correctly.

All my JD tractors have a fast governor. I run a 50kW Winpower and the Kill-A-Watt meter doesn't lose 1 Hz when the A/C compressor kicks on. Current tractor is a 1070. I even run this same PTO genny off my F-935 lawnmower.

And I live in Michigan.

It's actually called torque rise in a diesel engine, the ability for an engine to mantain a pre-determined rpm at a particular throttle setting. What I'm inferring to is when you exceed the torque rise of an engine (when you apply a load greater than the specified torque rise) you have to adjust the throttle accordingly.

No matter, I've owned and operated a PTO driven unit and it's no picnic for the reasons I described in a previous post.

Soo can I run a big generator with a light load powered by a BX?

When the engine starts to loose rpm under load the governor adjusts the throttle to keep the rpm constant, all tractors and almost all industrial engines have this.

Possibly but do you want your tractor running continuously to power a generator? Would not a dedicated generator work better?
I ask because I have had to go four days without power in an ice storm.

Don't plan to run it continuously but I would like the ability to run most of the utilities during the majority of the day. Biggest concern is with a big family it's typical for me to have thousands of dollars worth of food in the freezers and the heat here can become severe quickly especially after a bad storm in the summer so I really want to be able to run the AC too...sense everything else in house was electric when we moved in I'm kind of stuck with a lot of stuff drawing electricity I'd rather have on LP.

Plan on needing roughly 2HP/KW.
You list 2 tractors, an 1860 and a 25D. The 25D might just manage it.
The advantages of a PTO generator is that there is no engine to maintain, you don't need to run it a bit for maintenance, they are relatively small and you can easily swap the engine.

Plus sometimes you can get them cheap. A few years ago I bought a 12KW Winco, barely used WITH a nice PTO shaft (also barely used) for $600. Looking at todays prices a 10KW Winco w/ PTO would be about $1700.

If you only need 8KW and you DON'T have a generator I'd recommend a dual or tri-fuel and run it off NG or LPG, or go big time and get a military surplus 10 to 15KW diesel genset on a trailer.

I'd love to have a surplus 10k, unfortunately it doesn't fit with my current job due to moves. Neither does a bigger tractor but work with me

Yes, I do it all the time with my Kubota B6200. IF I need bigger power out put, I put a bigger tractor on the gen set...

Personally, I REALLY like my 15kw Winco pto genset, it works perfectly and I don't mind putting a few hours on my tractor, that's what it's made to do! Why spend money on a tractor, then be afraid to use it??

Once I get a partial load on my genset, I set the throttle on my tractor and the governor takes care of any increases, and BTW, EVERY tractor I've ever owned has a governor to increase fuel to the engine under load.

And another thing, using a higher gear (speed) on the pto on a small tractor, takes it out of it's power band, that's NOT good on the tractor and makes for poor power out put, as the governor is slow to respond to loads.

That's news to me. I have 2 large frame Kubota's (much larger than most owners on here have) and neither have a 'governor' that maintains engine rpm during load fluctuations on the PTO. In order for any engine to maintain a specific RPM loaded and unloaded they must have a load sensing fuel pump. Tractors don't.

Maybe things are different in Norway.

Are you running your tractor at PTO RPM or are you using a higher pto gear and running the engine slower to get the correct pto speed?? ... If the former you have a warranty issue with your tractor. Some tractors hold rpm better than others as load changes, but at pto rated rpm there are none as bad as you describe unless they are malfunctioning.

I used a PTO set for years. Worked well, but I am glad those days are over.

Unless I am wrong, no tractor has a shut down system for temp or oil failure. Something to think about before leaving a tractor running wide open unattended.
