Q: I have a old farmall 230 farm tractor will it drive this generator?
by Don Wackerle from Michigan on May 11, 2013

A: PTO generator sizing is based on the HP at the PTO and can be calculated using the following....

1000 watts for every 2 PTO HP.
by Jim, Product Expert

Q: Any problems using this exposed to the weather? Not all the time, just during power outages when it will probably be raining or snowing.
by Will from Kentucky on December 26, 2012

A: Per the owner's manual these units are not to be run in rain or snow.

Q: I have ordered the 12/15 Kw voltmaster pto generator from your online store, unfortunately the factory has a back order problem with parts so not sure when I will receive the generator, but would like to know what plug types I will need to hook up when I receive it.
Thanks, Joe

by Joe Croisant from Texas on August 11, 2012

A: The unit comes with the following outlets.....

Q: Bought a voltmaster pto15/12 generator with a 50 amp plug and a reliance transfer switch. The reliance switch came with a 50 plug with 3 prongs. It says it needs a CS6365 power cord plug type. Do you have cords to connect generator to plug in wall in garage.
by Bryan from Connecticut on April 05, 2012

A: The following cord has the correct connections to connect the generator to the Reliance Switch.

Gen-Tran 50A 25ft Cord

This cord has the following ends.....




by Jim, Product Expert

Q: Some of your generators say tractor horsepower and some say PTO HP which is it? I have a 35hp tractor with a 25hp PTO what is the biggest gen I could have hooked up to it?
by Rob Bridges from Illinois on January 31, 2011

A: The HP rating is based on the PTO HP and when looking at your PTO HP output the estimated generator size is based on the following: 1000 watts for every 2 PTO HP so for your 25HP PTO you can use a maximum 12,500 watt generator.

Jim's Recommendation

This PTO generator offers you a great value for 12kW of power. You can back up power to your farm or your house for the price of a portable generator.

As long as you have a tractor with a 24-HP engine you really can't go wrong with this value priced PTO generator.

Works Great

Mine works great, and the shipping was super freaky fast, as it was just over the state line. I had read the tachometer warning, and mine is slow. I got full power at 500 indicated. The unit starts my 6 HP compressor and after the first couple minutes even sounded quieter. I'll get back on this after 10-20 hours.

Good Generator For The Money

I bought this generator after a storm that knocked out power for 3 days. My welder/generator did just fine, but 1.5 gal of gas an hour was a bit much. I bought this pto generator, made a 3 pt hitch frame and bought a driveshaft at Tractor Supply, and tested it out and had no problems. Summer of 2012 we lost power in Maryland for 4 days. This generator ran about 102 hours continuously with no problems powered by a John Deere 1026r sitting beside a 300 gal diesel tank. PERFECT.

Great Pto Generator

I fabricated my own frame for this PTO generator when all I had was a 650 JD rated at 14 PTO hp. Although It was only good for producing 5 or 6 Kw with that tractor, it worked flawless. I did use a frequency meter to check against the pto setting on the tach and it is amazing, the tach is close enough. It's always 59 to 61 htz. Now with the 37 hp tractor it will play with this generator.

New Pto Generator

The unit arrived as promised and the carrier was great. Fortunately, I have not had to put the PTO Generator to full use, however, a test showed that the unit produced the correct current. I was able to set the my tractor to 2250 RPM to get 240 volts. This unit allows me to handle the house, barn, and shop without worrying about an overload.

Got the generator in good time from the order date. Several emails communicating how the order was processing. Ran the unit for an hour running the "whole house". Only thing i will add is a hz meter to dial it in since i am relying on the tractor governer to maintain speed.

My New Generator

We live in Northern California and have at least 2 or 3 two to four day power outages each winter, and several shorter ones.

I bought this generator to put behind my 45 h.p. tractor. It works and performs flawlessly as stated. I am very happy with it, and would recommend it to anyone who wants a PTO generator.

It took a couple days to build the stand for it, but it was well worth it. It runs smooth and puts out the proper voltage at 540 rpm's at the PTO unit.

Thank you for a good product, at a good price.

Awesome

I ordered this generator from EGD after Hurricane Sandy 2012. We had a similar event on the East Coast last year about the same time that left us without power for 5 days. Again in 2012, Sandy was another 5 days without power.

With the gas being the most common fuel for portable generators and the effect Sandy had on the East Coast, NJ and NY ran low on gasoline. I decided on this type of generator as I have a Cub Cadet 7 series Subcompact tractor that could run the PTO driven generator.

For the money you have all the power the average home will ever need, plus if you need to weld or w... more

The service and value of products from Electric Generators Direct is unbeatable. I researched extensively before my purchase and this was the best deal.

A Great Accessory For Our John Deere

We live in the country and depend on our own well. This model gives us enough power to run the pump and many other conveniences.

The wattage was right for us, the price was great (no need to pay for an engine), a great 3 year warranty, and it was made in the USA!

The available accessories made setup easy. We added furniture dollies to make the setup easy to move around when not attached to the tractor.

The quality of the three parts is top notch.

Now Satisfied

As stated in a previous review, I was having problems getting up to 60 Hz. Then I read an article from the Ontario Ministry of Ag on producing clean power from PTO generators, in which it was stated that tractor tachometers are notoriously inaccurate. So I tried the generator on my neighbor's tractor and all was fine: 60 Hz and 240 VAC.

I would recommend the article to anyone owning or considering purchasing a PTO generator. The website is: http://www.omafra.gov.on.ca/english/engineer/facts/00-059.htm

Not Yet Satisfied With This Product

I received my new PTO generator just in time for the East Coast storm. I made the concrete base for it according to the drawing furnished with the unit. I purchased a PTO shaft to attach to my more-than-adequate tractor for the generator.

At 540 RPM, the output was only 50 Hz and 77 Volts. Just below red lining the tractor, the output was only 55 Hz and 100 Volts. I will say that the folks who manufacture this unit (Winco) are responsive thus far, but to this point, there has yet to be a solution. Electric Generators Direct is just a middle-man, and all service questions are directed... more

35 Minutes Running...

First 35 Minutes of operation I noticed black dust coming out of the cooling exit duct. I noticed it because of the fresh paint on the metal frame I built. The generator was also abnormally loud in my opinion. Not quiet at all. There was plenty of airflow as I saw the grass below the frame moving in the breeze from the fan. I placed my hand near the vent and noticed shards of metal coming out as I could feel them on my hand. The generator shaft inside broke or it was not assembled properly. I haven't a clue. You can bet I will be returning it for a new one. All I had on it was my refrig... more

Voltmaster Pto/15/12 Generator

Got it installed on the 3 point hitch cart, and fired it up for the first time today. Really solid piece of equipment worked like a charm. A nice option for those who already own a diesel tractor with rear PTO. Took 3 months or so to receive it, but worth the wait.

Well I have attached it to my 57hp @ pto john deere tractor. Appears to be working fine. Except for oil leak around the gear box filler cap. Maybe new O ring will stop that. Also I have to run the rpm up to 2400 to get 220volts from the gen.
