PTO Generators, been here before?

[buickanddeere]

I have a friend who used a B7500 on a 15KW genset. We would put the PTO in 1000RPM and run the tractor just off an idle. The tractor had a tendency to try to overheat so we put a regular 110V box fan in front of the radiator to keep up the air flow. It worked pretty well and was efficient on fuel. However I did not care for the idea because the cost per hour to operate a tractor is significantly higher than a stand alone generator. I have a stand alone 9 KW honda powered genset, it replaced a Tecumseh 7 KW unit that I wore out. I am at the end of the line and have gone over 10 days without power. It is common to spend 5+ days a year powerless, I would hate to put those sort of hours on a tractor. I just spent 2K to rebuild the engine on the Massey, I can buy 2 Honda powered gensets for that cost. When we are running the generator I put synthetic oil in it and give it an oil change every 48 hours to try to get more life out of it. If I need power in the field I put the genset in the loader bucket and carry it with me.

Another example of these 1/2 throttle on a 1000rpm tractor connected to a 540rpm generator is not a good idea. The advocated to such abhorrent behaviours never calculated the actual costs using accurate facts.
For reasons unknown some people think 1/2 throttle = 1/2 the fuel used ???

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.

That is a rather bizzare ration formulated from 1/2 truths .

You know, there IS something between wide open and part throttle... At least there is on all of MY tractors...

It's called "pto speed"...

Then let's say operate at pto speed. I happen to have a few tractors that pto speed just happens to be WOT as designed from the factory.

Here is one: Digital Photo Sensor Tachometer

Killawat meter thingmajigger from the hardware store works very well to
Indicate voltage and frequency from inside the house if you want.

It appears that some of you guys could figure out a way to get into an argument with the sales lady at Victoria's Secret.

The money saved on buying a Honda will some day be put to good use buying hearing aids.

People think that since Honda is a good name in the lawn and garden world, that it somehow represents top notch, power generating equipment. Yes, maybe better then Harbour Freight.

LOL....true. To be fair, it seems most forums have more arguments in the winter...especially on a tractor forum where there isn't much tractor work being done in most places.

BTW, nice post on your Sandy experience

I have a Northerntool Northstar 13 kw pto genset. I think it is great. Every set up has its pros and cons and you will here that here. I also have a small portable gas powered unit to supplement. Both are wired into my main panel with a main breaker interlock. I love the fact that i always have a few hundred gals of diesel on hand when needed. The worries over no safety shutdowns for low oil or overheating are overblown in my opinion. No gen should be left running unchecked. The idea of putting hours on my tractor are akso over blown since this is what I purchased it for. To be used in sny way it serves me. Power is one of the best services it could provide when the power goes out for 5 days. I also do not run it 24 hrs a day. Price was another factor. I purchased mine hardly used for 600$. Try finding a 13 kw portable genset for that money.

???? Have you ever heard a good Honda generator? Unless your tractor is battery powered the Honda is quieter. Honda isn't a good generator? Honda is the generator that the rest are compared to.
