PTO Generator for YM 200BD

[scesnick]

I live in the middle of nowhere in the Md/Wv Mountians and my power always goes out. I have a 5,000 watt piece of junk generator that constantly surges with a load on it.
I have been looking at PTO generators. What is the biggest one that my YM 2000 will handle.
Also, Does anyone know of a good place on the web to find a deal on one? Thanks alot.

Northern Tool has a 13000 watt generator which needs 24 HP which your YM2000 is rated for. Their price is $ 1100. Here is the URL:

That generator is rated for 24 PTO hp. A YM 2000 has 20 hp at the PTO. I believe Northern has a smaller generator that would work.

"I have a 5,000 watt piece of junk generator that constantly surges with a load on it."

If choking makes your gen run better, a carb cleaning will probably fix it. Hunting/surging is usually fuel starvation, (lean), but could be governor problem if choke doesn't help.

If you are having to use a generator frequently, I would give this site a look see http://utterpower.com/ The fellow that runs this site specializes in low tech power solutions. I would give serious thought to one of the ST typ generators talked about but you would have to build a platform and the PTO drive but that shouldn't be too hard for a handyman. A decent ST gen head of 12kW should only run about $500 and you could build the rest including a pto shaft for another $200-$300. A 12kW ST gen head will weigh in at about 300 lbs. They are intended to run 24/7 for yrs on end.

20HP= 15kW but with losses I would limit the power to 12-13kW.

Mathmatical equivalents aside.. In practice, I've found most manufacturers want you to have about 2 pto hp per kw of generated electrical power.. I know there is 'fat' in there.. But just weight till the first really big 30-40-50 (inductive) motor load hits that "15kw" genny head with a 20 pto hp tractor powering it... I think you would be amazed at what would happen...

I was running about a 23pto hp tractor on the northern 12.5 kw genny, and hitting it with 20a inductive loads as well as some constant incandescent loads, and some 'test' electroninc loads, like a tv and radio.. looking for frequency and undervotlage distortion. While the genny did take a few minot rpm hits on large loads.. all stayed withing the 'green' zone indicated on the meter... If that had been a 20pto hp tractor.. I think I might have hit some out of range votlages / freq's. I'd prefer to have excess engine if I wanted to run at full rated watts, and also have surge capability. Course.. same can be said of the genny. If I had the money, I would much prefer to run a 12kw genny head at 8 kw, vs buying an 8kw head and running it at 8kw. It gives you so much excess surge power, pluss if your pto power source is ever upgraded, you are good to go. I know keep a 33 and 67 pto hp tractor ready for my pto gen if the lamps go out... I've no doubt the extra available hp will help stabilize governor movement during high load cut in's.. etc..

just my .02

Soundguy,
WoW !! You really confused me now.... I know as much about electricity as an amish farmer !! So are you saying I can run a 15 Kw or I need a smaller one??

15kw is probably a little more than your tractor can handle at full load, however I would get it anyway. You will not get the full 15 kw out put but you will have the reserve built in if you get a bigger tractor and you will not stress the generator head as much with surge current. Your tractor can probably run betewwn 12 and 13kw so 15kw is not that far off. You will just be gettin 12 or 13 kw out of the 15kw generator.

As has already been said, you can get a larger one but it will not deliver full power due to limit of your power source.

The ST gen heads I mentioned previously have a lot of rotating mass which helps with the transit loads and with one of these where you have to make your own drive you could easily include a flywheel to further help with transit loads. Oh, these gen head also only need to turn 1800 RPM for 60Hz.
