Generator pto generator / florida huricane

[Soundguy]

First.. a 'good luck' to my fellow floridians ( and that goes for you south georgia and carolina people as well ). Hope we don't get hammered too hard.

On a related topic. I think I've finally decided to purchase the 13000/12000 watt pto generator from northern tool. I see that it mentions an input shaft , 6 spline, 1 3/8"

I take that to mean that it has a standard male pto stub like our tractors do. Am I thinking correctly? If so, then i can get a 150$ 6 spline to 6 spline drive shaft from tractor supply locally, instead of ordering the 190$ + shipping $$ one northern sells. Anyone see a problem with this thinking?

Thanks!

Soundguy,

I can't help you with your question but have you checked on ebay for the PTO shaft? I've seen them on there for less than $100.00. I wouldn't have noticed them except for the recent thread where the guy tried to pull apart his stuck PTO shaft.

You are correct on the spline size.

Have you tried Agri-Supply.

Their prices are less than Northern Tool.

Taking a look there right now.

thnaks guys.

Soundguy,
Be sure and let us know how the generator turns out, I have been thinking of buying the same generator.

Good luck with Francine.

Thanks Chris, and it looks like I should bid you that double as the weather people here in Jax are now telling us that we will probably only be getting 40-50 mph winds starting Sat. and that further south will get it worse. I hope Ocala doesn't do any worse. Good luck with the generator. I will also be interested to know how it does as I am going to sell the RV and there goes my generator! John

Just remember that PTO shafts are rated for the amount of power they can transmit. For that generator @ 746 watts per hp with an 80% assumed efficiency you need about 21 pto hp to achieve rated output. Startup surges could be much higher. Good luck with the storm.

Kiotijohn and slowrev. As soon as I get the genny and get some use on it I'll post back about it.

Thanks for the thoughts.

Yep.. I agree. I had originally thought about a 150$ one from TSC as opposed to the 190$ one at northern, but I found out the TSC one was 36" and only rated for 24 hp.. I didn't feel too good about that, and moved up to a 50" one that was rated for 90hp, and that almost matches the specs line per line for the norhtern one.. so I felt much better about it. Still saved about 25$ over northerns cost.. so that was a good deal.

I also noticed that northern ran an unadvertised special on those 13/12kw gennies.. They are listed at 1099.00 in the catalog and the internet site.. but I got mine for 999.00?? Florida sympathy discount? Whatever.. I'll take it. That discount paid for half of the 'priority' shipping.. which i felt was a pretty reasonable rate for a truck freight item...

I just bought a 42" 40hp shaft from the local CaseNH dealer to use on my Bush Hog. Cost was just under $110.

I have had a PTO generator for 20 yrs. Takes a little while to hook up but works great. Mine is a 7KW but that was all I could drive with the B6100E Kubota I had. I will have to replace it soon as the electronics are beginning to fail and it is an orphan.

I live a stones throw from ocala... usually go there every day while working.

That 18kw genny was a bit big for an 8n. 8n is rated at 27.3 engine hp, and 23.3 pto hp.

My pto genny is going to be 13kw, and says it needs 24pto hp for full rated load.

I'll guess that genny would kick out 12.5-13kw if the 8n is in good order.

Definitely let us know how it works - I'm curious to see if the governor on the tractor can keep the voltage and frequency fairly constant when load changes.

You're really lucky that you have multiple tractors - relegating one of them to gen-duty during storms is the way to go.

 

[texbaylea]

You should get a 60Hz frequency meter to set the generator not a volt meter. I have a reed type that I picked up surplus many years ago. My test set that I built has the freq meter plus a volt meter in it. Seems like the voltage was always higher than expected. In the order of 125-135 v. A little hard on light bulbs but everything else generally was OK.

My dad lived in Ocala, in 'On-Top-of-the-World'. Really nice place. He moved to his 'last condo' as he called it about 11 years ago. Sure do miss him. Thanks for bringing up some fond memories. Hope all is well for the Florida friends......

The genny sopposedly needs 24 pto hp to run full load. I'll power it with my 33/34 hp 1954 NAA.. which has about 28/29 pto hp. If that won't keep up, I'll pull the Nh 7610s out and hook it up... with 90ish hp available.. I imagine it will be able to handle the load fine...

Yep.. and my wife actually agrees too.. It is nice leaving one hooked up to the mower.. one hooked to the box blade.. one for small mowing or pulling a cart.. etc.. one to pull a pasture drag.. etc... genny.. etc.

Heck.. For kicks I might let my old JD-B power it. It doesn't have a 3pt lift.. but does have a pto.. and it is inthe high 20's on hp as well... hearing that old pop-pop run would be great.

Yep.. I've got a freq counting vom.. should do the job.

And mrcaptbob.. great hearing from you.
ontop of the world is a nice place.

my pto generator has a built in frequency meter visible from the drivers seat so i can regulate it from there, i found if i set it at 1 to 1 1/2% over when i apply load it settles into a 60 hz without any difficulty. i have tried to overload it with cycvling the well, refridg, house stuff and it holds really steady after a second to stabilize. i run a 25 kw generac with a 19pto hp new holland, i dont get the full output on the generator, but the diesel sure has a whole lot of torque to keep the power steady during motor startup more than any gasoline genset i have ever had.

i also bought a dual voltage and freq. meter at radio shack, that just plugs into the generator or the 110 outlet, it also is pretty usefull.
