hp needed for genny?

[JB4310]

RFB,
From the look of both the tiger power and the IMD sites, AVR is only available on the 10 and 15 kw's, then it jumps up to the 45kw. what is that 6420 cvt, some kind of shuttle shift or power reverser?

Frank,
Mine is definetly a 2 pole head, as far as the 3 pt carrier goes, like you said once its on, you know it's not going to move much out of sync with the tractor.
That tiger power site is the best I've seen and has a lot of helpful info there, I don't know how long you had the unit but when they just give you a new one off the shelf that's a big confidence booster.
I am also the neighborhood helpful hillbilly, which helps them tolerate me running my small contracting bussiness out of my back yard.
As far as getting a new forum, I've tried that on my diesel truck sites with no luck, I think it takes an act of Conress.

Well I've got my new hertz meters today, so I'm going out to do some more experimenting, hope I don't blow something up!!!
I'll take a bunch more pictures, if for nothing else, entertainments sake.

RonMar, I like that fly wheeler, are they really as nice sounding as they say? whats the max rpm's 600-800? or is it even less than that? I did a lot of reading on those so called third world engines, stories like villagers working on 30 year old motors with tools made out of animal bones.

Yes, they are very pleasant to listen to. With my pulley to flywheel size, the engine runs about 630 RPM for a 60HZ output. It only needs basic hand tools to work on and I can have it stripped down for a rebuild if necessary in about an hour(that is piston, cylinder and liner out on the workbench). The lister CS series after which these engines were based, were known for their longevity and years of trouble free operation. This clone isn't quite up to the original production standards, but with a carefull measured setup, they can run many thousands of hours between overhauls. If you go to youtube or google video and search "listeroid", you will find a bunch of running videos.

frankc,

Can you elaborate on the advantages/rational for the 4 pole versus 2 pole issue? Is it the general issue of rpm's (as a mechanical advantage) or is there also an electrical factor to the choice?

Also, your points correct are regarding the cart versus carry-all choice. I was looking for a method that would accomplish the stability and alignment that a 3 point provides, and the roll-out/hook-up ease of the cart style. My current mental iteration is a 3 point carry-all type platform with industrial grade casters attached to telescoping legs on four corners(sort of like a trailer tongue jack): attach the carry-all, lift and align, then set the wheel length.

JB4310,

IVT is Deere's version of a continuously variable transmission(CVT).

I spoke with Tiger Power today. The 20 and 30 are also AVR and will be available in the 4 pole 1800rpm, are outdoor weather-rated (drip proof, not immersion-proof), and a 5 year warranty.

Frank: my first Tiger Power unit was flickering the lights pretty good called the dist up and they sent me the new version of 10kw w/AVR, the first unit looked like the IMD but the second one looks like IMD 100kw a lot bigger but still labeled 10kw. I was told they are phasing out the old style. they replaced it no ? asked. GREAT customer service and pleasant to talk with!!!!!!!

RFB, in regards to 2-pole or 4-pole;

My little brain simply can't get past 1/2 the revolutions of the 4-pole should mean twice the life. Whether that pan's out or not I guess we'll see.

Also, when dealing with the concept of turning this thing from a 540rpm pto drive, I'd just guess that the HorsePower cost of multiplying mechanically a 3.3 ratio climb to get 1800rpms for the 4-pole costs Less than multiplying it by 6.6 to climb to 3600rpms for the 2-pole. Although, no one is ever going to confuse me with a mechanical engineer and I couldn't begin to justify those thoughts, lots of trying to put HP to the pavement experience says I can't be all wrong in my thinking.

Cam, Yeah the tiger-power guys really are easy to deal with! You actually get the feeling that there are still business people that want their customers to be happy!!!!!!! I think were both lucky though that we live so close to the source of the product. Couldn't tell you how well dealing thru a distributor would work out.

Wasn't aware that they've changed their lineup, my 30Kw has the AVR setup and the digital Frequency gauge as it will only be 2 years old this coming May. Actually my first gen head would be 2 years old this coming May, this one won't be TWO till Sept. How lucky was that that I bought this thing 4-5 weeks before actually needing it for 4 straight days???? I grew up within 1 mile of where I live now, (farms back then!) and in my whole life we never lost electric longer that 2 days. Usually 8-24 hrs at the most! What's really weird is I happened to pickup a used Jinma Chipper 3 days before the storm hit, and I used that chipper for 3 straight days cleaning up from the storm. Sometimes I scare myself!!!!!!!!!!!!

Mentioning that, obviously I have a great wife to put up with all my EXPERIMENTS and toys! Since that day, she doesn't ask why I need more than one machine, cause we were easily the most functional household within many miles. SO, my message to everyone who says buy a separate generator so you can use your tractor during an emergency is: BUY A PTO generator so you can justify to the wife why you need more than one tractor!!!

POWER GENERATION CATEGORY ----- Please??

Ron, thanks for the pic of your lister/ST setup. By looking at it I'd almost bet you've visited the UtterPower site.

A little food for thought for those thinking about building/buying a genset.

* Bearing capacity is relaetd to bearing speed. Slower speed means higher capacity or longer life for a given speed.

* KISS is a good guide to keep in mind when looking for things like a genset. When you really need that genset, reliability and easy of repair beats fancy smancy every time. Brushless designs are something you can't repair in short order.

* If you are building a pto genset and have to build your own drive, a 4 pole 1800 rpm gen head is lower cost to built than a 2 pole 3600 rpm gen head. Also in building a genset and drive, one can always include a flywheel to help overcome those large transient loads.

* The ST gen heads that have been mentioned are simple in design with only the oversized, std size, bearings and a set of long wearing brushes that possibly could fail. Many of the ST gennys come with a spare set of brushes. Brushes can be replaced in a few mins, 5-10. With these gennys coming from China, qlty can vary but some importers are buying these with higher qlty components.

Back with a little more real world testing with my 10 kw, put the new LED Hz/volt meter in and made some good observations, this is just the 2nd time fooling around with this type of whole building back feed repower set up, done in my small shop which is normally powered by a separate 100 amp service (not part of the houses system).
The shop is a good place for testing, since I have some moderately heavy loads to experiment with, a 5kw heater, 15 amp-5hp air compressor, 1kw work lights, bench grinders, drill press, etc etc.
First of all and maybe most importantly, the difference between the 1980 23 pto hp Ford 1700 and the 2003 25.5 pto hp JD 4310 is very noticeable, so different tractors are going to react differently even though they may be in the same hp class, The Ford could only handle about 3.5kw from no load before manual up throttle was needed to keep Hz at the 60 green light, the 5 kw heater was a little trickier, the Hz dropped to 58 or less and required more fuel, had maybe max 8 kw load total, the rpms stayed right at the 540 setting and the tractor seemed to handle it no problem once dialed in. the compressor would not start until I dropped pressure to about 25 psi.
shutting off the big loads is also a little nerve racking as the output really spikes.

The JD handled the challenge much much better, almost full recovery with 5 kw draw from no load and will start the compressor at a normal on cycle around 90 psi. the JD put the meter in the green at below the 540 setting on the tach and sounded very nice not loud at all.
I learned a simple trick, to set the no load volts as high as possible before the Hz goes over out of the green (see picture) by doing so, once the load is applied there is already a buffer there, I know this is not a brain storm, just a simple logical thing to do, but by doing this in unison with the JD's superior governor, there required very little additional human input.
I'll paste some pics,
